Patient leaflet - Trolactin 200 mg prolonged-release hard capsules

1. What Trolactin is and what it is used for

Trolactin contains the active substance dipyridamole. This belongs to a group of medicines called ‘anti-thrombotic agents’, which are used to stop blood clots forming.

Trolactin is used:

  • To reduce the risk of having another stroke in people who have had a stroke caused by a blood clot in the brain.

2. What you need to know before you take Trolactin

Do not take Trolactin:

  • if you are allergic to dipyridamole or any of the other ingredients of this medicine (listed in section 6).

Warnings and precautions

Talk to your doctor or pharmacist before taking Trolactin:

  • If you have angina or other heart diseases or have had a recent heart attack
  • If you have myasthenia gravis (muscle weakness)
  • If you have any bleeding problems.

If you are having heart tests

Trolactin contains dipyridamole. Dipyridamole is also sometimes given as an injection during tests to see if the heart is working properly (also called ‘myocardial imaging’). This means that the test and your medicine may contain the same substance. If you are going to have an injection of dipyridamole, tell the doctor that you are taking Trolactin.

Children and adolescents

Trolactin should not be given to children since the safety and efficacy has not been established.

Other medicines and Trolactin

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. This includes herbal medicines. This is because Trolactin can affect the way some other medicines work. Also some other medicines can affect the way Trolactin works.

In particular, tell your doctor or pharmacist if you are taking any of the following medicines:

  • Medicines for high blood pressure
  • Medicines for muscle weakness (myasthenia gravis), called a ‘cholinesterase inhibitor’
  • Adenosine, used for heart problems or tests on the heart
  • Warfarin, acetylsalicylic acid or other medicines to stop blood clots forming
  • Theophylline (a medicine for respiratory problems).

Pregnancy and breast-feeding

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor for advice before taking this medicine.

Trolactin should generally not be used in pregnancy.

Trolactin should only be used during breast-feeding if your doctor considers it essential, since dipyridamole is excreted in breastmilk.

Driving and using machines

You may feel dizzy while taking Trolactin. If this happens do not drive or use any tools or machines.
