To treat high blood sugar, metformin HCL 500mg is taken along with a healthy diet, an exercise routine, and maybe other drugs. Those with type 2 diabetes use it. Keeping blood sugar levels under control helps prevent kidney damage, blindness, nerve damage, limb loss, and issues with sexual function. Your chance of having a heart attack or stroke may be reduced if your diabetes is well controlled. The way that metformin works is by assisting in restoring your body's appropriate reaction to the insulin that you naturally make. Also, it reduces how much sugar your liver produces and how much sugar your stomach and intestines absorb.
Before starting to take metformin and each time you get a refill, read the Patient Information Booklet if it is available from your pharmacist. You should speak with your doctor or pharmacist if you have any questions.
If prescribed by your doctor, take this medication by mouth with meals as often as once to three times daily. If your doctor has not instructed you otherwise, make sure to drink lots of water while taking this medication.
