While hallucinations are not a common side effect of Percocet (oxycodone and acetaminophen), they have been reported in rare cases. Hallucinations are perceptions of things that are not actually present, and they can be visual, auditory, or sensory.

Other possible side effects of Percocet include dizziness, drowsiness, nausea, vomiting, constipation, and headache. These side effects are generally temporary and may go away after a few days of treatment. However, if you experience hallucinations 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.
