As others have pointed out, you really need the advice of your Doctor.
However, here is another thing you might want to check on with the pharmacist (presumably you get your PRESC. filled at the same pharmacy consistently?)
If not, all bets are off.
Anyhow, have you been getting brand name or generic version of the drug?
Although by law, generics are required to have the exact same amount of the ACTIVE therapeutic ingredient, there are also what’s known as “binding agents ” or other fillers.
Supposedly these are totally inert. In practice, however, they can sometimes affect how it is dispersed in the body.
You should check with your pharmacist to ask him whether the manufacturing company is the same or different. Changes from one company to the next happens routinely since generics are totally price based for most pharmacies and they order based upon price fluctuations regardless of manufacturer.
Obviously this doesn’t happen with original brand name drugs so its presumably a consistent product from one time to the next.
But that’s not so with generics and something as seemingly minor as a different binding agent from a different company can effect SOME people differently.
Talk to your pharmacist and then your Doctor.
