Promethegan is used to relieve the symptoms of allergic reactions such as allergic rhinitis (runny nose and watery eyes caused by allergy to pollen, mold or dust), allergic conjunctivitis (red, watery eyes caused by allergies), allergic skin reactions, and allergic reactions to blood or plasma products. Promethegan is used with other medications to treat anaphylaxis (sudden, severe allergic reactions). Promethegan is also used to relax and sedate patients before and after surgery, during labor, and at other times. Promethegan is also used to prevent and control upset stomach and vomiting that may occur after surgery, and to help relieve pain after surgery. Promethegan is also used to prevent and treat motion sickness. Promethegan is in a class of medications called phenothiazines. It works by blocking the action of a certain natural substance in the body.
Promethegan comes as a tablet and syrup (liquid) to take by mouth and as a suppository to use rectally.When Promethegan is used to treat allergies, it is usually taken one to four times daily, before meals and/or at bedtime. When Promethegan is used to treat motion sickness, it is taken 30–60 minutes before travel and again after 8–12 hours if needed. On longer trips, Promethegan is usually taken in the morning and before the evening meal on each day of travel. When Promethegan is used to treat or prevent upset stomach and vomiting it is usually taken every 4-6 hours as needed. Promethegan may also be taken at bedtime the night before surgery to relieve anxiety and produce quiet sleep. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take Promethegan exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor. Promethegan suppositories are for rectal use only.
