I have been taking 500MG Metformin 2X a day. My old pills had ANDRX 674 on one side and 500 on the other. My latest bottle has Z one one side and 70 on the other. Are the new ones still 500MG? Thank you.

This is to answer Clifton,yes those are the same type of medication.Different companies manafacture Metformin.Generic medications(such as your metformin) must meet the same requirements as it's branded counterpars

Rebeca,like I said to Clifton many companies make Metformin and so there will be many imprints for each indavidual company.

My pharmacy changed their source for Metformin 1000mg from a pill # GP 128 to pill # M 244. Since then, about 2.5 weeks, my numbers have risen from 50 to 100 pts. One pill has the surphur odor, the GP128, and the new one doesn't. Can anyone explain?

The Imprints on the pills will vary greatly from manufacturer to manufacturer.

There are many generic manufacturers and each one of them will make a pill that looks different. There are no rules saying that pills with the same ingredient have to look the same! The size, color, shape and imprint will all vary from manufacturer to manufacturer.

The only relevant regulations from the FDA state that they must have unique imprints for identification purposes, but these will even differ by manufacturer and strength of the med.

And as to John's comments about them having to meet the same requirements as their name brand counterparts, well that just ain't necessarily so!

The FDA allows generic manufacturers to make pills that differ as much as plus or minus 20% from the name brands, so if a company has poor quality control, you can end up with some pills that have too much or not enough of the active drug!

Generic drugs must also only be BIOEQUIVELENT, meaning a drug can act in the same way, but does not have to be identical to the name brand's ingredients. And the inactive ingredients, binders/fillers do not have to be the same at all, which can effect how some people react to some drugs.

Here's the information page for it:


This one is manufactured by Caracoa, there really haven't been any reported problems with the reliability and efficacy of their drugs.

i take Metformin with a Z on one side and a 70 on the other and since the pharmacy switched me to this manufacturer ,I have had nothing but problems. I have been dizzy, spaced out, and can't get a true focus . I have headaches constantly and trouble expelling my urine. My doctor is on an extended vacation. Not sure about going to someone new. Anyone else experiencing any of my symptoms?

if it is oval with a 93 on one sie and a 48 on the other side stop taking it now. My husband ended up in the hospital after taking only one of these. He was previously taking the round ones. Our pharmacist said he had at least one other woman call in complaining that her sugar went up to 300 when she switched to the new manufacturer. Our doctor has also had a couple of other patients who are having problems with this manufacturer's metforman 500mg the manufacturer's name is on the bottle as Teva,

Recently I switched pharmacies to save money and found my metformin was from Sandoz and now is from Heri. My blood sugar keeps rising. Then my doctor put me on low dose, 20 mg. pravachol, and after 1 pill my blood sugar dropped 30 points! I am also having greater night sweats...uggghhh.
