Glipizide

Diabetes

Also known as Glucotrol

Glipizide is a pill for type 2 diabetes. It works by telling your pancreas to release more insulin, which lowers your blood sugar. Because it actively pushes sugar down, it can push it too low — so the most important skill with this medicine is knowing the signs of low blood sugar and how to fix it fast.

How to take it

When

Usually taken about 30 minutes before breakfast, exactly as prescribed. Taking it before your first meal helps it match the food you're about to eat.

Food

Don't skip meals after you've taken it. The medicine keeps working whether you eat or not, and no food plus more insulin is how lows happen.

Avoid

Go easy on alcohol — it makes low blood sugar more likely and can hide the warning signs.

Know your lows

Shakiness, sweating, confusion, or a racing heart can mean low blood sugar. Have fast sugar right away — juice or glucose tabs — then a snack. Carrying medical ID is a smart move.

Missed a dose?

If you miss a dose, take it as soon as you remember — but if it's close to your next dose, just skip the missed one. Never double up to catch up.

Common side effects

Low blood sugar (shakiness, sweating, hunger)
Dizziness
Upset stomach or nausea
Headache
Mild weight gain over time
