Hereās the deal with genericsā¦ I am a certified pharmacy technician and have been told this by every pharmacist I worked with.
Generics have the exact same active medication as the brand name. The difference is that generics are allowed by the FDA to have 10% more, or 10% less, of that active medication. For example, a 100 mg tablet of brand name Seroquel is required to have exactly 100mg of Quetiapine in it. But a generic 100mg tablet of the same drug is only required to have 90mg of Quetiapine in it, or even up to 110mg.
Thatās why some people notice that certain generic manufacturers are better than others. For instance a lot of people who take Xanax generic say the Greenstone generics are best and thatās true because they contain more of the actual drug.
Normally I only take the brand names. I think there is no generic for my invega and my lexapro so Iām sort of safe there. Iāve never been told by a doctor to only take brand names, itās been my own pedantic self that has seen me only order the brand names.
However, when I first bought my seroquel I thought I had said I only want the brand name, but I ended up with the generic. Iāve never had the brand name before so I canāt speak on the difference, but I love the generic. I think it has been working. It helps me sleep and I think my recent flare up of āsymptomsā is dying down.
@Sooner88 I didnāt know about the 10% rule. Do they have to advertise the amount on the box or can they say it has the right amount but it really doesnāt?
When I was addicted to codeine I always bought brand name except from one chemist where the generic felt stronger. The generic at my regular chemist was way weaker and I couldnāt get high from it.
Oh wow! I didnāt know there was generic invega. Itās actually really hard to get in Australia. If you take your prescription to the chemist, they usually have to order it in for you. Chemists donāt keep it stocked. So I always get the brand ordered in.
Although in saying all that, my regular chemist keeps it in stock for me now.
āFACT: FDA requires generic drugs to have the same quality and performance as brand name drugs.ā
āThe generic drug manufacturer must prove its drug is the same as (bioequivalent) the brand name drug. For example, after the patient takes the generic drug, the amount of drug in the bloodstream is measured. If the levels of the drug in the bloodstream are the same as the levels found when the brand name product is used, the generic drug will work the same.ā
@Moonbeam I found this on the TGA (therapeutic goods Australia, the equivalent of the FDA) website:
Apart from containing the same active ingredient, generic brands also
have to be ābioequivalentā. That is, if you take the same dose of a
generic medicine as an existing medicine, the same amount of active
ingredient is absorbed by your body over the same period of time.
