What are some of the side effects that you can get if you take opioids?

Like all medications, opioids have side effects:

Nausea: Very common with opioids. If nausea and vomiting are severe but your doctor feels that this is a good medication for you, you may be given an anti-nausea medication. For some people, the nausea goes away after a few doses.
Constipation: Very common as well and should be taken seriously. Be sure to drink plenty of fluids and increase your dietary fiber. You could ask your doctor about laxatives or stool softeners.
