Fentanyl side effects
Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat. Stop using fentanyl and call your doctor at once if you have any of these serious side effects:
weak, shallow breathing;
severe weakness, drowsiness, or confusion;
cold, clammy skin; or
feeling light-headed or fainting.
Less serious fentanyl side effects may include:
nausea, vomiting, stomach pain, constipation;
dizziness, drowsiness, headache;
pain or mouth sores where the tablet was placed.
This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.
The odd story for me is that my only side effect is gas. All the time, and lots of it! Every time I change position, when I am walking across the room, standing up, sitting down- all during water aerobics. It started with my patch,from the second day on. My nickname here at home now is Farty Mcfarts.
