Generic vs brand prescriptions – why brand is always best

23rd August 2018

There are often different variations of anti-epileptic drugs (AED), this is because different brands may have slight bioavailability variations.

Branded medication

Once a new medication is developed, only the company that developed it are allowed to produce it, this is known as being ‘on patent’. After the patent runs out (10 years) other companies are free to create their own brand of the medication. These companies will then  brand the medication with their own name, such as Tegretol, which is a brand name of the AED, carbamazepine.

Generic medication

Generic medications are labelled by the main active ingredient, this is the part of the medication that treats the condition. Often, these medications are referred to by their generic name. This means that a person could be prescribed a generic version rather than the branded one they’re used to.

What can happen if you switch drugs between brands?

Although the differently branded medications will contain the same active ingredient, the dosage and other ingredients may vary. Even the smallest variations can have some effect and lead to breakthrough seizures, anxiety and other side effects. Ensuring that you are always prescribed the same brand of a medication will mean you always get the same version. Consistency is key to effectively managing seizures and if you have found an AED that works for you it’s crucial it isn’t changed unless recommended by a healthcare professional.

What can I do to ensure I receive the right prescription?

If you’re worried about getting a generic version of your AED prescription, rather than the specific branded version, there are a few things you can do:

Make sure you’re familiar with your medication

Many people don’t even realise they have been given a different version of their AED prescription. Make sure you know the generic name and brand name of the medication you’re used to. You should also make a note of the shape, colour and size of your AEDs. This way you can prevent being given a generic version.

Speak to your neurologist

If you have concerns you can speak to your neurologist, if they agree that it’s crucial for you to always receive the same version of your AED they should give your GP instructions to always prescribe the same medication.

Speak to your GP

It’s likely that your GP will be responsible for your prescription. You can ask them to write the brand name, rather than the generic name, on your prescription to prevent being given the generic medication.

Speak to your pharmacist

If you regularly use the same pharmacist, you could ask them to make a note of the brand name and ask to ensure you always receive the same brand. That way if they don’t have your usual brand version in stock, you can choose to take your prescription to another pharmacist who does.
