Opiate withdrawal occurs when a person who has become dependent on opiates suddenly stops taking them or significantly reduces their dosage. Opiate withdrawal can be a very uncomfortable and distressing process, as the body tries to adjust to functioning without the drug.

Opiate withdrawal symptoms typically include:

Anxiety and irritability
Insomnia
Sweating
Nausea and vomiting
Muscle aches and pains
Dilated pupils
Runny nose and teary eyes
Diarrhea
Cravings for the drug

The severity of withdrawal symptoms can vary depending on the type of opiate used, the amount of the drug taken, and the length of time the person has been using opiates. In some cases, withdrawal symptoms can be so severe that medical supervision is necessary to manage symptoms and prevent complications.
