Before taking nimodipine
Before taking nimodipine make sure your doctor or pharmacist knows:
- If you are pregnant or breast-feeding.
- If you have kidney or liver problems.
- If you have porphyria (a rare blood disorder).
- If you have angina and have chest pain when you are resting as well as during any exercise.

How to take nimodipine
- Before beginning treatment, read the manufacturer's printed information leaflet from inside the pack.
- Take nimodipine exactly as your doctor has told you.
- The usual dose of nimodipine is two tablets every four hours with a drink of water. A course of treatment usually lasts up to 21 days.
- You may take your doses before or after food.
- Do not drink grapefruit juice while you are on nimodipine. This is because grapefruit juice increases the levels of nimodipine in your blood.
