Side effects of painkillers

Strong painkillers have three common side effects – drowsiness, sickness and constipation. The drowsiness usually wears off after a few days, so it should be possible for you to be free of pain and still be alert enough to do all that you want to do.

If you feel sick, anti-sickness pills can help, and the sickness usually settles gradually over a few days.

Constipation is such a common side effect that everyone taking strong painkillers should take a laxative regularly; many people need to take one which softens the stools and one which stimulates the bowel. Ask your doctor, nurse or pharmacist for advice. Don’t be afraid to vary the dose of your laxatives to keep your bowels moving easily.
