Glucophage (metformin)
Glucophage is usually the first drug I recommend for
type 2 patients who need medicines to get their blood sugars back to normal.
This medicine has been used in Europe for decades and has been available
in the United States for about five years. It works by helping the insulin
that your body is still making work better. It also has a side effect which
is very beneficial for most people with type 2 diabetes—it makes you lose
a little bit of weight by decreasing appetite. Another good side effect
for some people is that it tends to lower triglycerides
(certain fats in the blood), which is great if you tend to have high triglycerides.
The big plus if you take it by itself without any other diabetes medicines
is that it never causes low blood sugar by working too much.
Glucophage is available in three dosage forms: 500, 850
and 1,000 milligrams. When I start my patients on Glucophage, I usually
give them 500 milligrams once a day with food. After a week, if they are
not having any gastrointestinal problems, I tell them to go up to two pills
a day. Most people need the full dose to have an effect. The highest dose
that seems to be effective is 1,000 milligrams twice a day. Alternately,
you could take 850 milligrams three times a day, but since it is hard to
take a pill three times a day, I usually try to have people take the 1,000
milligrams dose twice a day.
