An Introduction to Kadian Side Effects

As with any medicine, Kadian^® (morphine sulfate ER) can cause side effects. However, not everyone who takes the medication will have problems. In fact, most people tolerate it quite well. If side effects do occur, in most cases, they are minor and either require no treatment or can easily be treated by you or your healthcare provider.

(This article covers many, but not all, of the possible side effects with Kadian. Your healthcare provider can discuss a more complete list of Kadian side effects with you.)

Common Side Effects of Kadian

Kadian has been studied thoroughly in clinical trials. In these studies, the most common side effects of Kadian included:

Drowsiness -- in up to 9 percent of people
Constipation -- up to 9 percent (see Kadian and Constipation)
Nausea -- up to 7 percent
Dizziness -- up to 6 percent
Anxiety -- up to 6 percent.

For most people, drowsiness and nausea will significantly improve after taking Kadian for a week or so. If nausea is severe, your healthcare provider may recommend an anti-nausea medication for a few days, until your body becomes accustomed to Kadian.
