from£99.99
Nalcrom (sodium cromoglycate) 100mg capsules help prevent allergic reactions to foods by stabilising mast cells and stopping the release of allergy-triggering chemicals. They’re usually taken before meals and can be used by adults and children.
Nalcrom (sodium cromoglycate) 100mg capsules are a prescription-only anti-allergy medicine designed to help prevent the symptoms:
of food allergies
mastocytosis
mast cell activation syndrome (MCAS)
It’s beneficial for people who struggle to avoid all food triggers or who react to trace amounts.
Sodium cromoglycate works by stabilising mast cells in the body. These are the cells that release histamine and other chemicals during an allergic reaction. By stopping this release, Nalcrom can prevent swelling, itching, tummy pain, and other allergy symptoms before they start [1][2].
Nalcrom capsules are typically used alongside a careful diet. They’re not a substitute for avoiding trigger foods, but they can make accidental exposures less severe and help people live more confidently.
Nalcrom is suitable for adults and children, with doses tailored to age and weight. It’s available as capsules or, for those who struggle with tablets, as an oral liquid [1].

Overview
Nalcrom (sodium cromoglycate) 100mg capsules are a mainstay in the management of food allergies and mast cell disorders. They work by stabilising mast cells, which are responsible for releasing histamine and other chemicals during an allergic reaction [1].
For many people, avoiding all food triggers is nearly impossible. Nalcrom provides an extra layer of protection, reducing the likelihood and severity of reactions if you’re accidentally exposed to an allergen. It’s especially useful for children, who may find strict avoidance more challenging.
Nalcrom is not a cure for food allergies and does not treat acute reactions (like anaphylaxis). Always follow your allergy action plan and carry emergency medication if prescribed [2].
Active ingredient: Nalcrom (sodium cromoglycate) 100mg capsules
Each Nalcrom capsule contains 100mg of sodium cromoglycate. This is a mast cell stabiliser, meaning it helps stop allergic reactions before they begin by preventing mast cells from releasing histamine and other chemicals [1].
What are Nalcrom (sodium cromoglycate) 100mg capsules for?
Nalcrom is used to help prevent the symptoms of food allergies, which can range from mild itching and stomach pain to more severe reactions like swelling or breathing difficulties.
It’s also sometimes used for certain rare gut disorders involving mast cells, such as mastocytosis, mast cell activation syndrome (MCAS) and for people who react to multiple foods or who can’t avoid all triggers [1][2].
How does Nalcrom (sodium cromoglycate) 100mg capsules work?
When you eat a food you’re allergic to, your immune system reacts by activating mast cells. These cells release histamine and other chemicals, causing allergy symptoms.
Nalcrom (sodium cromoglycate) stabilises mast cells, making them less likely to release these chemicals—even if you’re exposed to an allergen.
By taking Nalcrom regularly before meals, you can reduce the risk and severity of allergic reactions. It’s a preventative medicine, not a treatment for acute attacks [1][2].
How to use Nalcrom (sodium cromoglycate) 100mg capsules
Take your Nalcrom capsules exactly as prescribed, usually four times a day before meals.
Swallow the capsules whole with water, or open and mix the contents with a little hot (then cooled) water if preferred.
Try to take each dose 30–60 minutes before eating. For the oral liquid, follow the manufacturer’s instructions (typically 15 minutes before meals).
If you forget a dose, take it as soon as you remember, unless it’s nearly time for the next one. Don’t take two doses together.
