Your medicine

The name of your medicine is Duromine. Duromine capsules contain the active ingredient, phentermine. Phentermine is combined with a resin which slowly releases the phentermine so the effect of Duromine lasts all day.

What Duromine is used for

Duromine is used to reduce body weight in obese or overweight patients. Your doctor will determine if you are overweight enough to use Duromine. Duromine works by directly affecting the area of the brain that controls your appetite making you feel less hungry.
Duromine should be used as a part of an overall weight management plan which should include a medically controlled diet and exercise program.
Duromine is only available with a doctor’s prescription. It has been prescribed for you only.  Do not give it to anyone else even if their condition is the same as yours. Your doctor may prescribe Duromine for another purpose. If you are not sure why you are taking this medicine ask your doctor.
Note: Duromine is a controlled drug C5. It should be kept in a secure place and under no circumtances should it be given to anyone else.

Using Duromine

How to take Duromine

  • In adults and children over 12 years, the usual dose of Duromine is one capsule every day. However, your doctor will prescribe the right dose for you.
  • Take Duromine first thing in the morning, at breakfast time so that it does not keep you awake at night.
  • Swallow Duromine capsules with plenty of water. Do not chew or open the capsules.
  • Follow your doctor’s instructions exactly and never change the dose yourself. Increasing the dose may not necessarily make you lose more weight or make you lose weight faster. However you will most likely experience more side effects. Your doctor will tell you how long you are to take Duromine for.

Duromine is not recommended for elderly patients or for children younger than twelve years.

While you are using Duromine

  • You should regularly visit your doctor for a medical check up.
  • Tell your doctor immediately if you experience sudden or rapid weight loss, difficulty breathing, chest pain, fainting, swelling of the lower limbs and if you can not exercise as much as you usually can.
  • Be careful driving or operating machinery until you know how Duromine affects you.
  • DO NOT drink alcohol whilst taking Duromine.
  • Check with your doctor or pharmacist before you start to take any cough or cold medication.

If you forget to take Duromine

If you forget to take your Duromine dose at breakfast take it no later than lunchtime. Alternatively, skip the dose you missed and take your next dose at the normal time on the next day. If you take Duromine any later than lunch-time you may have trouble sleeping at night.
Never take a double dose to make up for a dose you have missed. If you have trouble remembering when to take your medicine, ask your pharmacist for some hints.
