4head Stick is a solid 35% levomenthol roll-on applicator, used for the topical cooling relief of migraine, severe headache, tension headache, and neck ache in adults, older adults, and children aged six and over.
The pocket-sized 3.6g stick is rolled directly across the forehead, temples, or back of the neck to deliver an immediate cooling effect.
Supplied in the UK by Courier Pharmacy with pharmacist-led advice and discreet home delivery.
4head Headache Treatment Stick is a roll-on levomenthol applicator for cooling relief. It can help with migraine, severe headache, tension-type headache, and neck-related tension pain.
Each stick contains 3.6g of product. It comes in a small twist-up applicator. The formula feels like a smooth, wax-based balm.
How it works (and what it feels like)
Roll the stick over clean, dry skin on the forehead, temples, or the back of the neck. It leaves a thin layer of levomenthol on the skin. Then the balm softens with body heat. As a result, you get a fast cooling sensation.
Why people like the stick format
This is the original 4head format. Many long-term users know it well. It also fits easily into a handbag, glovebox, or desk drawer. So, it’s a practical option when you need cooling relief on the go.
Who makes it and how we supply it
Diomed Developments (part of the Dendron family of brands) makes 4head. It has been a UK headache-care staple since the late 1990s. We supply 4head Stick from our UK-registered pharmacy. Plus, a GPhC-registered pharmacist checks every order before dispatch.
When it can help most
If you want a non-tablet layer, this stick can be a good add-on. For example, you can use it when you’d rather not take extra oral painkillers. You can also use it alongside paracetamol, ibuprofen, codeine combinations, or a triptan.
However, it won’t stop a severe migraine on its own. Still, many people find it comforting. It can also help ease that tight, “band-like” tension feeling.

Five key takeaways
4head Stick is a solid levomenthol stick applied directly to the forehead, temples, or back of the neck for the relief of migraine, severe headache, tension headache, and neck ache.
Each stick contains levomenthol 35% w/w in a wax-based solid base that melts gently onto the skin and delivers cooling, counterirritant relief.
The 3.6g pack is the original 4head format, designed to be small enough to fit in a pocket or handbag and used as often as needed throughout the day.
Suitable for adults, older adults, and children aged six and over, including during pregnancy and breastfeeding (with usual cautions).
Courier Pharmacy supplies 4head Stick with full pharmacist oversight, personalised guidance, and free fortnightly community clinics in Derby.
Treatment dosage 4head Stick
Twist the base of the applicator to extend a small amount of the stick. Roll the stick gently across clean, dry skin on the forehead (the most common location), the back of the neck (for tension headaches that radiate from the upper neck), or the temples. A thin, almost invisible film of levomenthol is enough; you don’t need a visible coating. Replace the cap to keep the stick from drying out and discolouring.
4head Stick is not subject to the same dosing restrictions as oral painkillers. You can reapply as often as needed throughout the day, typically every 30 to 60 minutes if cooling has worn off, and you can use the stick alongside oral analgesics such as paracetamol, ibuprofen, naproxen, codeine combinations, or a triptan. If the skin becomes irritated, apply less often or use a smaller amount; if irritation becomes uncomfortable, stop using the stick and clean the area.
The stick works at room temperature and doesn’t need refrigeration, although some people find that storing it somewhere cool gives a slightly more intense initial cool. Keep the cap firmly closed between uses so the levomenthol doesn’t evaporate from the surface of the stick. Don’t apply to broken or irritated skin, and avoid the eyes, eyelids, nostrils, and mouth.

Headache and migraine are remarkably common. UK data suggests around a third of adults experience a migraine in any given year, and almost everyone has tension-type headaches occasionally. For mild-to-moderate headaches, oral painkillers like paracetamol or ibuprofen are the first line. For people whose stomachs don’t tolerate NSAIDs, who are pregnant, who want to limit their tablet intake, or who simply prefer non-drug options where possible, topical cooling treatments fill a useful gap.
4head Stick’s mechanism is straightforward. The high-concentration levomenthol in the wax stick melts gently onto the skin on application, triggering cooling-sensitive nerve fibres in the skin (TRPM8 receptors) and producing the characteristic chill sensation almost immediately. That cooling and counterirritant effect helps relax tense head and neck muscles, soothes throbbing temples, and gives the nervous system something to focus on that isn’t the underlying pain. It’s the same physiological pathway that makes rubbing a knock or holding a cold compress against an injury feel better.
It’s worth being honest about what 4head Stick isn’t. It’s not a treatment for the underlying cause of recurrent headaches or migraines. It’s not a substitute for a triptan or other prescription migraine treatment if those are what your migraine pattern needs. It also isn’t going to fully abort a severe migraine on its own; it’s an adjunct that takes the edge off and adds comfort. For some people that’s all they need; for others, layering it with oral medication delivers better overall control.
The stick format earns its keep in a specific way: portability. The QuickStrip hydrogel patch is excellent for sitting at a desk or lying down for a few hours, but it’s not always practical when you’re on the move. The 3.6g stick lives in a coat pocket, slips into a handbag, and can be applied in seconds in a meeting, on a train, or in the school car park without anyone noticing. For people whose headaches build through the day and need topping up rather than treated in one go, that pocket format is genuinely useful.
Many of our patients arrive after years of being told their headaches are tension or stress, with no plan beyond “try paracetamol”. We don’t subscribe to that framing for clear migraine patterns or for headaches that significantly interfere with daily life. Whether you’re managing chronic migraine, hormonal migraine, fibromyalgia overlap, MCAS care, or chronic fatigue care that fits your life, the goal is to find a regimen that respects your body’s signals rather than overriding them. 4head Stick sits comfortably in many of those plans, alongside other approaches.
The bigger picture for any recurring headache pattern involves trigger identification, sleep, hydration, regular meals, screen-time management, and where appropriate, prescriber-supervised preventive treatment. Topical sticks like 4head are a useful tool, not the whole toolkit. Our community work in Derby is one way we try to live up to that.
Why choose Courier Pharmacy for 4head Headache Stick
We started Courier Pharmacy because too many people were being handed prescriptions like takeaway flyers, with no conversation, no follow-up, and no sense that anyone had actually listened. Even for a simple consumer product like 4head Headache Stick, that ethos matters. Personalisation means looking at your wider headache or migraine picture and helping you decide whether the strip is a useful addition to your toolkit or whether you’d benefit from something else entirely.
Guidance carries through after the order goes out. Our GPhC-registered pharmacists are reachable for the smaller questions that often go unasked: why isn’t my headache responding to anything? Should I be tracking my headache pattern? Is it time to ask my GP about triptans or a preventer? Our medical lead, the figure behind much of our clinical thinking, is Dr Ada Jex-Cori, an evidence-led, community-rooted clinician who built her practice on the belief that people with chronic pain conditions deserve to be heard before they’re prescribed.
Trust is the part that has to be earned, not claimed. We’re a UK-regulated pharmacy, we publish our processes, we tell you when a product probably isn’t enough for what you’re describing, and we’d rather point you to your GP than sell you something that won’t help. Whether you’re navigating chronic migraine, hormonal migraine, fibromyalgia support, MCAS care, or chronic fatigue care that fits your life, we’ll meet you where you are.

Active ingredient in the 4head Headache Stick
The main active ingredient is levomenthol at 35% weight-for-weight, contained within a solid wax-based stick. Levomenthol (also called L-menthol or natural menthol) is a familiar cooling agent that activates TRPM8 (transient receptor potential melastatin 8) channels on cold-sensing nerve endings in the skin. This triggers a cooling sensation even at body temperature, which is the central pain-modifying mechanism of the stick.
The 35% concentration is notably higher than that found in most consumer menthol products, which is why 4head Stick produces such a strong, immediate cool with even a thin film. The wax base melts at skin temperature, releasing the levomenthol onto the upper skin layers in a controlled way. As the menthol slowly evaporates from the skin, the cooling sensation gradually fades over 30 to 60 minutes, at which point a fresh application can be made.
What is the 4head Headache Stick used for?
4head Stick is for the cooling and topical pain-relief of migraine, severe headache, tension-type headache, and tension-related neck ache. It can be used on its own for milder headaches or as an adjunct to oral painkillers and migraine-specific medications during a more significant attack.
It's particularly useful when oral painkillers aren't an option or aren't enough on their own. People who are pregnant or breastfeeding, who have stomach problems that limit NSAID use, who are sensitive to caffeine in combination products, or who simply prefer a non-drug option where possible all find topical cooling sticks useful. It's also handy as a layer on top of usual treatment for migraine flares where every comfort measure counts.
A note on chronic illness contexts. People with fibromyalgia, CFS/ME, or MCAS often look for non-drug options when their tolerance for additional medication is limited. 4head Stick is a low-risk addition to most regimens; the main thing to check is menthol sensitivity, since some people with MCAS react to menthol-based products. We'll explore your specific pattern during the consultation, including a patch-test recommendation if you have known fragrance or menthol reactivity.
How does the 4head Headache Stick work?
Pain perception isn't a one-way signal travelling from the painful site to the brain. It's a busy two-way conversation, and the brain constantly weighs pain signals against other sensory input. When you stub your toe and rub it, the rubbing doesn't make the toe physically less injured; it just gives the nervous system competing input that softens the pain signal. This is the gate control theory of pain, and it's a big part of why topical cooling and counterirritant treatments work.
4head Stick works through a single dominant mechanism: chemical cooling via levomenthol. At 35% concentration, the menthol delivered by even a thin film of the stick activates TRPM8 cold receptors in the upper skin layers within seconds. These receptors fire as if the skin were genuinely cold, sending cooling signals through the trigeminal nerve (the main nerve serving the forehead, temples, and front of the scalp) and back into the brain's sensory cortex.
That trigeminal activation matters because it shares neural pathways with migraine and tension headache pain itself. Activating cooling-sensitive trigeminal fibres dampens the perception of pain-carrying trigeminal signals at the same time, which is partly why menthol products can feel disproportionately helpful for forehead and temple pain specifically.
Many migraines also involve a tension component in the muscles of the back of the neck and across the forehead. The cooling effect of the stick helps these muscles relax slightly, and the small ritual of stopping, applying, and pausing for a moment encourages overall muscle relaxation. For some people that's where the stick earns its keep most clearly: not by chemically blocking pain, but by triggering a cascade of small comforts.
Onset is essentially immediate; you feel the cool within seconds of applying the stick. Peak effect is reached within 5 to 10 minutes. Duration per application is typically 30 to 60 minutes, after which the stick can be reapplied as often as needed. The stick's lower per-application duration compared with the QuickStrip patch is the trade-off for its portability and ease of reapplication.
How to use the 4head Headache Stick
Make sure the skin is clean and dry before applying. Avoid moisturisers, sunscreen, or makeup at the application site, since these can interfere with how the stick glides on and how the cooling sensation feels. Twist the base of the applicator to extend a small amount of the stick, remove the cap, and gently roll the stick across the skin.
Apply to the forehead (the most common location), the temples (in a small circular motion), or the back of the neck (for tension headaches that radiate from the upper neck). You only need a thin, almost invisible film of product. A heavier application doesn't intensify the cooling and increases the risk of skin irritation. Replace the cap firmly after use.
Practical tips from our pharmacists: try the stick on a small patch of skin first if you've not used a menthol product before, particularly if you have sensitive skin or known fragrance reactivity; pausing for a few minutes with the cool film on the forehead intensifies the relaxation effect; avoid applying immediately before a hot shower or in a sauna, since the cooling will feel uncomfortable in that contrast; and apply somewhere below the hairline to avoid menthol vapour drifting into the eyes. Reapply whenever the cooling sensation has worn off and the headache is still bothering you.
Warnings and precautions for the 4head Headache Stick
4head Stick is well-tolerated by most people, but a few cautions apply. Don't use the stick on broken, cut, grazed, sunburnt, or actively inflamed skin (such as eczema flares), because absorption is unpredictable and irritation is more likely. Don't use it in cases of known hypersensitivity to levomenthol or to any component of the stick. Keep the stick away from the eyes, eyelids, nostrils, mouth, and other sensitive mucous membranes.
Children aged six and over can use 4head Stick with adult supervision. For children, apply the stick yourself rather than letting them apply it, to make sure they don't accidentally rub their eyes or apply too much. Children under six should not use the stick. The pocket size makes the product easy to misplace, so store sticks out of reach of younger children, especially if there are older siblings who use them.
During pregnancy and breastfeeding, 4head Stick is generally considered safe to use because systemic absorption of menthol from a small skin patch is minimal. The manufacturer notes that products of this type have been in widespread use without significant adverse reports, although formal safety trials have not been conducted. If you have frequent or severe headaches during pregnancy, mention this to your midwife or doctor, since severe headaches can occasionally indicate raised blood pressure or other conditions that need assessment.
Faint skin redness is a common and harmless effect at the application site. In rare cases the initial cooling can feel quite intense; if uncomfortable, gently wipe the area with a tissue and clean with cool water. The stick is mildly volatile and gives off a small amount of menthol vapour, which can cause temporary, mild watering of the eyes in some people, particularly if applied close to the hairline. This usually settles within a few minutes.
Allergic reactions to menthol are uncommon but possible. Symptoms of an allergic reaction include itching, swelling, persistent redness, or hives at the application site. Wipe off the stick film, wash the area gently with cool water, and don't use the stick again if a reaction develops. Seek medical advice if symptoms are widespread or severe.
Side effects with the 4head Headache Stick
4head Stick has a strong safety record. The most common reported effects are local: faint skin redness at the application site, which usually settles within minutes, and a strong initial cooling sensation that some people find intense for the first few seconds. Both are generally part of the expected effect rather than signs of intolerance.
Less common effects include temporary, mild watering of the eyes (because the menthol vapour is mildly volatile and can drift towards the eyes), and a slight tingling or numbness at the application site. These resolve quickly. People with very sensitive skin may notice more pronounced redness or mild itching, which can usually be reduced by using a smaller amount or applying less often.
Rare reactions include skin allergy with persistent redness, itching, swelling, or a more pronounced rash. Stop using the stick, wash the area, and avoid further use if this happens. Very rare hypersensitivity reactions including more widespread symptoms can occur and warrant medical attention.
If something feels wrong, trust that signal. Stop using the stick if you experience symptoms suggesting a serious reaction, including widespread rash, breathing difficulty, facial swelling, or any systemic symptoms, and seek medical attention. Most issues with 4head Stick are minor and local, but allergic reactions are always worth taking seriously.
Suspected side effects can and should be reported to the MHRA via the Yellow Card scheme at yellowcard.mhra.gov.uk. Reporting helps build the safety picture for everyone, including for established products.
Drug interactions with the 4head Headache Stick
Because 4head Stick is applied topically and has minimal systemic absorption, the formal drug interaction list is essentially empty. There are no known clinically significant interactions between 4head Stick and oral medications, prescription painkillers, antihypertensives, antidepressants, or anticoagulants.
This means 4head Stick is a useful adjunct to many treatment regimens. It can be used alongside paracetamol, ibuprofen, naproxen, codeine-containing combinations, or migraine-specific medications like triptans, without dose-stacking risk. People taking warfarin or DOACs can use the stick without affecting their anticoagulation. People on SSRIs or other antidepressants can use it without serotonin syndrome concerns.
The only sensible caveat is to avoid using multiple topical menthol products on the same area of skin at the same time. If you're already using a forehead-applied product (such as Tiger Balm, a peppermint oil roll-on, or 4head QuickStrip), don't layer 4head Stick on the same spot. Choose one and stick with it for that session, or alternate locations on the head.
Topical NSAIDs like ibuprofen gel or diclofenac gel applied to the forehead or temples are generally not recommended; the area isn't a typical NSAID application site, and combining topicals on the same skin increases the risk of irritation. Stick to one approach per session.
Frequently asked questions about 4head Stick
What is 4head Stick used for?
4head Stick is for the cooling relief of migraine, severe headache, tension-type headache, and neck ache. It can be used alone for milder headaches or alongside oral painkillers and migraine medications as a non-drug layer of relief. It's not a treatment for the underlying cause of recurrent headaches.
How quickly does 4head Stick work?
The cooling sensation begins within seconds of applying the stick. Peak effect is reached within 5 to 10 minutes. The cooling effect typically lasts 30 to 60 minutes per application, after which the stick can be reapplied as often as needed.
What's the difference between 4head Stick and 4head QuickStrip?
The stick is a solid roll-on levomenthol applicator that provides a quick, intense, shorter-lasting cool (30 to 60 minutes) and is easy to carry and reapply. The QuickStrip is a hydrogel adhesive patch that delivers gentler cooling for up to 6 hours from a single application. Many people use both: the strip when they can sit or lie down for a while, the stick when they're on the move.
Can I use 4head Stick with paracetamol or ibuprofen?
Yes. 4head Stick has minimal systemic absorption and doesn't interact with oral painkillers. Many people use the stick alongside their usual paracetamol or ibuprofen for a layered approach to migraine or headache relief.
Can I use 4head Stick with triptans for migraine?
Yes. Triptans like sumatriptan work systemically through serotonin receptors; 4head Stick works topically through cooling. There are no known interactions. Using the stick alongside a triptan during a migraine attack can add a comforting cooling layer.
Is 4head Stick safe in pregnancy?
Generally yes. Topical menthol is poorly absorbed, and products of this type have been used widely during pregnancy without significant adverse reports. The manufacturer notes that formal safety trials haven't been conducted, so use sensibly. If you have frequent or severe headaches in pregnancy, mention this to your midwife or doctor, since severe headache can indicate other conditions that need assessment.
Can children use 4head Stick?
4head Stick is suitable for children aged six and over, with adult supervision. For younger children, apply the stick yourself rather than letting them apply it. Children under six should not use the stick. The stick is generally a more child-friendly format than the QuickStrip patch because it doesn't need to stay in place on the skin.
How often can I reapply 4head Stick?
As often as needed. There's no fixed limit. Most people reapply every 30 to 60 minutes if the cooling has worn off and the headache is still bothering them. If skin irritation develops, apply less often or use a smaller amount.
How long does a 3.6g stick last?
This depends on how often you use it, but most people find a 3.6g stick lasts several months of intermittent use. The stick can last considerably longer if you only use it during occasional headaches or migraine attacks. Keep the cap firmly closed between uses to prevent the levomenthol evaporating from the surface.
Will 4head Stick interact with my prescription medicines?
No. Because 4head Stick has minimal systemic absorption, there are no known clinically significant interactions with prescription medicines, including antihypertensives, antidepressants, anticoagulants, anticonvulsants, or pain medications. It's a safe addition to most treatment regimens.
Can I use 4head Stick for tension headaches as well as migraines?
Yes. The stick is intended for migraine, severe headache, tension-type headache, and neck ache. Many people find the stick particularly useful for the tense-shoulder-and-neck pattern of tension headaches, applied at the back of the neck rather than the forehead.
Why does 4head Stick make my eyes water?
The menthol in the stick is mildly volatile, meaning it gives off a small amount of vapour. This can drift towards the eyes if applied close to the hairline, causing temporary mild watering. The effect is harmless and settles within a few minutes. Applying the stick slightly lower on the forehead usually solves the issue.
Can I store 4head Stick in the fridge for extra coolness?
You can. The stick works without refrigeration, but some people prefer the more intense initial cool of a refrigerated stick. Don't freeze it, as that can crack the wax matrix. Keep the cap firmly closed in the fridge to prevent the levomenthol from absorbing fridge odours.
Will 4head Stick stain my skin or hair?
No. 4head Stick leaves only a very thin, almost invisible film on the skin that doesn't stain skin, hair, or fabric. The stick does have a strong menthol smell which can linger for a while after use, but it dissipates within an hour or two.
Can people with MCAS use 4head Stick?
Some people with MCAS tolerate menthol well; others react to it. We always recommend a patch test on a small area of skin (such as the inner forearm) for 24 hours before using a menthol product if you have known fragrance or essential oil sensitivities. Tell us about MCAS during your consultation so we can give you specific advice.
Is 4head Stick vegan and vegetarian-friendly?
Yes. 4head Stick doesn't contain any animal-derived ingredients and is not tested on animals. The levomenthol and wax base are all plant or synthetic in origin.
How is 4head Stick stored?
Store at room temperature, out of direct sunlight, with the cap firmly closed between uses. The stick has a long shelf life when stored correctly. If the stick has dried out, lost its smell, or stopped producing a cooling sensation, replace it.
Can 4head Stick be applied near the eyes?
No. Keep the stick away from the eyes, eyelids, and the area immediately around them. Menthol on the eye surface can cause significant irritation, and even the vapour close to the eyes can cause watering. Apply to the central forehead, temples (carefully), or the back of the neck.
Will 4head Stick stop my migraine?
On its own, 4head Stick is unlikely to fully stop a severe migraine, but it can ease symptoms and add a comforting cooling layer. For people whose migraines are frequent or severe, oral painkillers, triptans, or preventive treatment may be more effective. The stick works best as part of a wider plan rather than as a standalone treatment.
When should I see a doctor about my headaches?
See your GP if headaches are frequent (more than twice a month), severe, changing pattern, accompanied by other symptoms (vision changes, weakness, fever, stiff neck), or affecting daily life significantly. Sudden "thunderclap" headache, headache after head injury, or any headache with neurological symptoms warrants urgent assessment.
