Is promethazine a narcotic or an opioid?

Is promethazine an opioid or a narcotic?

Promethazine is neither an opioid nor a narcotic. It is an antihistamine used for allergies and other conditions such as nausea and motion sickness. It does not produce opioid effects (like pain relief via opioid receptors) and is not classified as an opioid medicine.

Why do people sometimes think promethazine is a narcotic?

Some products combine promethazine with an opioid, such as codeine or other opioid pain medicines. In those combination products, the opioid component is the narcotic/opioid—not promethazine by itself. The confusion often comes from the combination drug name rather than promethazine alone.

What is promethazine classified as instead?

Promethazine is generally regulated and prescribed as an antihistamine (with antiemetic and sedating properties), not as a controlled opioid/narcotic.
