Information about taking metformin: Inside the pouch

Let’s delve inside the pouch to find out the facts about this popular Diabetes and PCOS medication.

Metformin is taken by thousands of people in the UK. It’s primary use is treating Diabetes, or preventing Diabetes for those in a high-risk group. Though not officially approved for PCOS (Polycystic Ovarian Syndrome), it’s often used in treating this condition.

How does metformin work?

Metformin is a useful medication for Diabetes because it helps regulate blood-sugar levels. It does this by reducing the amount of sugar your liver releases into your blood. It also makes your body respond better to insulin, which controls the level of sugar in your blood.

Can everybody take metformin?

Metformin is suitable for adults, and children aged over 10.

Metformin may not be suitable for you if you:

  • previously have had an allergic reaction to metformin or other medicines in the past
  • have uncontrolled diabetes
  • suffer with liver or kidney problems
  • have a severe infection
  • are being treated for heart failure or have recently had a heart attack
  • have severe problems with your circulation or breathing difficulties
  • drink a lot of alcohol

Let your doctor know about any of these issues before you start taking metformin. You should also tell your doctor if you are due to have surgery under general anaesthetic, or a scan than relies on injecting iodine into your blood.

Which pouch will my metformin be in?

This depends on which type of metformin you take. Metformin comes as 2 different types of tablet: standard-release and slow-release.

Standard-release tablets release metformin into your body quickly. So, you may have several daily doses. We will follow your doctor’s prescription instructions when organising metformin into your PillTime pouches. Each pouch is labelled with full details of your dose, so you’ll know exactly when to take your metformin.

Slow-release tablets dissolve slowly. This means that you do not have to take them as often. You will normally have one dose a day, in your evening pouch.

Metformin should be safe to take when pregnant. You can also take metformin whilst breastfeeding. Small amounts will pass into your milk, but not enough to affect your baby.

That said, you should always let your doctor know if you are trying to get pregnant, pregnant or breastfeeding. They will be able to advise you on your medication during this period.
