What is promethazine hydrochloride ?

Promethazine hydrochloride is a prescription drug. It's available as an oral solution, a rectal suppository, and an oral tablet.

The rectal suppositories are available as the brand-named drugs Phenadoz, Phenergan, and Promethegan. They are also available as generic drugs. The oral solution and oral tablet are only available as generic drugs. Generic drugs usually cost less. In some cases, they may not be available in every strength or form as the brand-name version.

This drug may be used as part of a combination therapy. This means you may need to take it with other medications.

Application:
Promethazine is used to prevent and treat nausea and vomiting related to certain conditions (such as before/after surgery, motion sickness). It is also used to treat allergy symptoms such as rash, itching, and runny nose. It may be used to help you feel sleepy/relaxed before and after surgery or to help certain narcotic pain relievers work better. It may also be used for a short time to treat a runny nose due to the common cold.

Promethazine is an antihistamine and works by blocking a certain natural substance (histamine) that your body makes during an allergic reaction. Its other effects (such as anti-nausea, calming, pain relief) may work by affecting other natural substances (such as acetylcholine) and by acting directly on certain parts of the brain.
