What is Omacor courierpharmacy.co.uk

Overview: Omacor (Omega-3-Acid) 1000mg 100 Capsules

  • Prescription-only omega-3 for high triglycerides and heart health
  • Contains purified EPA and DHA, the “good” omega-3s
  • Clinically proven to lower blood fats and support recovery after a heart attack
  • Easy to take capsules, usually with meals

Omacor (Omega-3-Acid) 1000mg 100 Capsules is a trusted option for adults with high triglycerides, especially when lifestyle changes alone haven’t done the trick [1]. The key ingredients—EPA and DHA—are the same omega-3s you’ll find in oily fish, but at a much higher, prescription-strength dose [2]. These fatty acids are essential for heart health and can help reduce the risk of further heart problems after a heart attack [3].

Unlike standard supplements, Omacor is made to strict pharmaceutical standards. That means you get a consistent dose and reliable results every time. It’s also been shown to reduce inflammation, support blood vessel health, and even help with certain types of high cholesterol when prescribed by your doctor [1].

Why prescription grade omega 3 fish oils matter courierpharmacy.co.uk

Most people take Omacor as part of a wider plan to improve their heart health. This usually includes a healthy diet, regular exercise, and sometimes other medicines to control cholesterol or blood pressure [3]. Your healthcare team will tailor your treatment to your needs, and regular check-ups will help make sure you’re on track.

If you’re considering Omacor, or your doctor has recommended it, this guide will help you understand what to expect and how to get the best results. Read on for a deep dive into how Omacor works, how to use it safely, and answers to the most common patient questions.

As always, if you have concerns about your heart health or cholesterol, speak to your GP or pharmacist for personalised advice [1].

Omacor for heart protection after a heart attack courierpharmacy.co.uk

Active ingredient: Omacor (Omega-3-Acid) 1000mg 100 Capsules

The active ingredient in Omacor is omega-3-acid ethyl esters, which is a highly purified blend of two essential fatty acids: EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) [2].

These are the "good" fats found in oily fish, but Omacor provides them in a concentrated, pharmaceutical-grade form for maximum benefit. Each capsule contains 1000mg of omega-3-acid ethyl esters, with at least 84% being EPA and DHA combined [1].

EPA and DHA help reduce triglycerides, support heart health, and may reduce inflammation in the body [3]. Unlike many over-the-counter fish oil supplements, Omacor is carefully purified to remove impurities and contaminants, making it a safe and reliable choice for patients who need prescription-strength omega-3s [2].

What is it for? Omacor (Omega-3-Acid) 1000mg 100 Capsules

Omacor (Omega-3-Acid) 1000mg 100 Capsules is used to treat adults with high levels of triglycerides (a type of fat found in your blood) when lifestyle changes alone haven’t been enough [3]. High triglycerides can increase your risk of heart disease, stroke, and pancreatitis, so keeping them under control is vital for long-term health [1].

 

This medicine is also prescribed to people who have had a heart attack, to help protect the heart and reduce the risk of further problems [2]. It’s usually part of a broader plan that includes diet, exercise, and sometimes other medicines to manage cholesterol and blood pressure.

Omacor is not a general supplement and should only be used under the supervision of a healthcare professional. It’s designed for people who have specific medical reasons for needing a high dose of omega-3s, rather than those looking for a basic fish oil supplement [3].

EPA and DHA what they do in the body courierpharmacy.co.uk

How does it work? Omacor (Omega-3-Acid) 1000mg 100 Capsules

The main way Omacor works is by lowering the amount of triglycerides in your blood. Triglycerides are a type of fat, and high levels can lead to a build-up in your arteries (atherosclerosis), which increases your risk of heart attack and stroke [1].

Omacor’s active ingredients, EPA and DHA, help to reduce the production of triglycerides in the liver and increase the breakdown of fats, resulting in lower levels in your bloodstream [3].

Beyond lowering triglycerides, Omacor has been shown to have anti-inflammatory effects, which may benefit the heart and blood vessels [2]. Some studies suggest it can also improve the health of the lining of your blood vessels, making them more flexible and less likely to develop dangerous plaques.

For people who have already had a heart attack, Omacor can help reduce the risk of another event by making the blood less likely to clot and by protecting the heart’s cells from further damage [1].

It’s not a cure-all, but it’s a valuable tool in the fight against heart disease when used as part of a wider treatment plan.

It’s important to remember that Omacor isn’t a quick fix. It works best when combined with healthy lifestyle changes, such as eating a balanced diet, staying active, and not smoking [3]. Your healthcare team will guide you on how to get the most benefit from your treatment.

If you’re unsure about how Omacor works or whether it’s right for you, don’t hesitate to ask your doctor or pharmacist for more information [2].

How to use it? Omacor (Omega-3-Acid) 1000mg 100 Capsules

Always take Omacor exactly as prescribed by your doctor. The standard dose is 2 capsules daily, but your doctor may increase this to 4 capsules per day if needed [2].

Take the capsules with meals to help reduce stomach upset and swallow them whole with a glass of water—do not chew or open them.

Try to take your capsules at the same time each day to help you remember. If you forget a dose, just take the next one as usual; don’t double up to make up for a missed dose [1].

If you have any questions about how to take Omacor, or if you experience any problems, speak to your healthcare provider for advice tailored to your needs [3].

Warnings and precautions: Omacor (Omega-3-Acid) 1000mg 100 Capsules

Before starting Omacor, tell your doctor if you have any allergies, liver problems, or bleeding disorders, or if you’re taking medicines to thin your blood (like warfarin or aspirin) [2]. You may need extra monitoring or dose adjustments in these cases.

Recent advice from the MHRA warns that high doses of omega-3-acid ethyl esters (like Omacor) may increase the risk of atrial fibrillation in people with cardiovascular disease or risk factors, especially at 4g daily.

If you develop symptoms like palpitations, chest pain, or breathlessness, seek medical help and speak to your doctor about whether to continue treatment [3].

Always tell your healthcare team about all the medicines and supplements you’re taking to avoid potential interactions [2].
