Common Side Effects of Morphine Sulfate ER
Interestingly, these common
morphine side effects usually occur less frequently and less severely in people with severe pain. People who have little or no pain are more likely to experience severe
morphine sulfate ER side effects.
For most people, drowsiness and nausea significantly improve after taking
morphine sulfate ER 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 morphine sulfate ER.
