> Does it differ between Metformin Regular & Metformin > XR? Yes.
2000 mg is max for the extended release (XR aka ER)
2550 mg is max for the regular
These maximum numbers are for healthy kidneys and close monitoring of serum creatinine.
May GOD continue to heal our hearts with HIS living water so that we can love others a little bit more, dear neighbor whom I love unconditionally.

Chrome - 02 Dec 2006 12:40 GMT > What's the maximum dosage per day of Metformin > which doctors prescribe? > > Does it differ between Metformin Regular & Metformin > XR? This is the generally accepted rule: Metformin HCI
The usual starting dose is one 500-milligram tablet twice a day, taken with morning and evening meals. Your doctor may increase your daily dose by 500 milligrams at weekly intervals, based on your response up to a total of 2,000 milligrams.
An alternative starting dose is one 850-milligram tablet a day, taken with the morning meal. Your doctor may increase this by 850 milligrams at 14-day intervals, to a maximum of 2,550 milligrams a day.
The usual maintenance dose ranges from 1,500 to 2,550 milligrams daily. If you take more than 2,000 milligrams a day, your doctor may recommend that metformin be divided into three doses, taken with each meal.
Metformin XR
The usual starting dose is one 500-milligram tablet once daily with the evening meal. Your doctor may increase your dose by 500 milligrams at weekly intervals, up to a maximum dosage of 2,000 milligrams a day. If a single 2,000-milligram dose fails to control your blood sugar, you may be asked to take 1,000-milligram doses twice a day. If you need more than 2,000 milligrams a day, the doctor will switch you to regular metformin.

Susan - 02 Dec 2006 23:01 GMT > So why would the max daily dose differ between XR & Regular? I dunno, perhaps because it isn't processed/excreted as quickly, a littler dab'll do ya. :-)

I know that when I was first put on it my doctor and the Diabetes Teaching Centre said that 2500mg. was the max.

Larry - 04 Dec 2006 19:14 GMT Cloudbrains: 3 grams/day?? Well this drug is more for obesity/lipid control more than anything else at that dose.!! The drug company responsible ( which one??) really need to start addressing the pharmacologic aspects of this drug. IMHO it is primarily to deal with obesity/T2 ! Very few reports suggest the contary.

: Larry I don't believe tha tMetformin is used primarily as a product fo rdealing with obesity. It may result in an average weight loss of about 8 lbs! Not a great deal if one is obese. It deals with the release of glucagon from the liver, giving you less glucose running around in the bloodstream, as well as helping with insulin resistance, not pirimarily fo rweight loss at all. It doesn't tend to cause you to gain weight as inculin or actos and avandia can.

Cloudedbrains" <donna_williamson"@ - 04 Dec 2006 22:26 GMT Metformin is used in people likely to have a level of insulin resistance! Its one of the primary drugs used in t2's IK as its proven to work extremely well! I only take 1000mg a day as dont tolerate more even on the slow release!

Very few reports suggest the contary. Actually, it's not a weight loss or lipid lowering drug at all.
It improves insulin sensitivity and, to some degree, inhibits glucose release from the liver.
