Migraine medication from chemist is different

[Tarrarra]

I went to collect my migraine medication yesterday I’m on sumatriptan. I noticed that they gave me two different boxes which initially I thought it was okay because different generic medication looks different. However, I then realised that I’ve had an issue with some medication working better than others which shouldn’t be the case if they’re all the same formula. So I checked the product number and they were different unpaid tablets one is playing sumatriptan and one is a sumatriptan succinate. I asked the pharmacist and she said no they’re both the same and work the same but I don’t think this is true does anyone have any knowledge on this? I find that the sumatriptan succinate works slower and leaves me queasy. Am I within my rights to take it back and ask them to swap it for the plane sumatriptan? After all I’m not prescribed sumatriptan succinate.

Sorry just noticed my auto correct fails.. plain not playing and plain not plane. I blame the migraine...

AFAIK sumatriptan succinate in the generic name. Sometimes how quickly you take it from the onset of the migraine affects how quickly it works as your digestive systems starts shutting down. It's far more likely to be coincidental rather than a causal connection. That said, if you're worried the medication isn't right for you talk to your GP. A different triptan might be better for you.

I have tried other trip times this is the one that normally works best for me

Triptans not trip times!

As I stated, when you take sumatriptan when you have a migraine can affect how fast acting it is. Speak to your GP about your concerns.

Are you sure that both aren’t sumatriptan succinate? As far as I know all the tablets are this salt form? Which brands are they?

I seem to get different brands every time these have different product codes and are different sized tablets. This time One is Accord sumatriptan succinate pl 20075/0371 and the other is Teva Sumatriptan pl00289/0588

They are the same - migraine is weird and everyone's migraines are different.

Teva sumatriptan also contains sumatriptan in the succinate form so they are exactly the same just labelled differently. This is the medical information sheet

I take amitriptyline for migraine prophylaxis and have found that one brand do not give me the same effect as another. I only realised on the second time I was given this particular brand rather than the regular one. I was getting increasing migraines by the end of both months. I spoke to the pharmacist who said this can be a thing, and does affect some people. He put a note on my record to only give me the Teva ones in future.
I did a bit of searching online and there are several published articles about this subject where people swapped from one brand to another have a relapse. Apparently it’s to do with bioavailability, the other ingredients in the tablet, amongst other things. Surprisingly the testing that a company does to check its drug has the equivalent effect of the original one is very small scale, with a minimum of Only 12 participants.
Let your pharmacist know for future prescriptions that you don’t want that particular brand again.
