Weight gain is not a common side effect of Percocet (oxycodone and acetaminophen). However, opioid medications like Percocet can cause fluid retention, which may result in temporary weight gain. In addition, some people may experience increased appetite or decreased activity levels while taking Percocet, which can also contribute to weight gain.

If you experience weight gain or any other unusual symptoms while taking Percocet, it is important to talk to your healthcare provider. They may be able to adjust your dosage or recommend other treatment options that can help manage your symptoms.

It is also important to use Percocet only as directed by a healthcare provider, and to avoid taking more than the prescribed dose. Overdose is a serious risk associated with Percocet and other opioid medications, and can cause symptoms such as slow or shallow breathing, extreme drowsiness, confusion, and unconsciousness. If you or someone you know is experiencing symptoms of a Percocet overdose, it is important to seek emergency medical attention right away.
