Phenergan
Phenergan
Phenergan (/fɛnərɡæn/), also known as Promethazine, is a type of antihistamine that is often used to treat allergies, insomnia, and nausea.
Etymology
The term "Phenergan" is a brand name derived from its generic name, Promethazine. The generic name "Promethazine" is derived from the Greek words "pro-", meaning "before", and "methazo", meaning "to transfer". This refers to the drug's ability to block the effects of naturally occurring chemicals in the body.
Usage
Phenergan is primarily used to treat allergy symptoms such as itching, runny nose, sneezing, itchy or watery eyes, hives, and itchy skin rashes. It is also used to prevent and control nausea and vomiting during and after surgery. It can also be used to help people relax and fall asleep before and after surgery, during labor, or with certain medical procedures.

Side Effects
Like all medications, Phenergan can cause side effects. These may include drowsiness, dizziness, dry mouth, blurred vision, or constipation. If these effects persist or worsen, medical attention should be sought. Serious side effects, though rare, should be reported immediately. These may include slow heartbeat, severe dizziness, fainting, or seizures.
