Consult your doctor before using Promethazine, especially if you have asthma, glaucoma, or enlarged prostate. This isn’t a substitute for professional medical advice.
Uses of Promethazine
Promethazine primarily acts as an antihistamine, effectively reducing allergy symptoms like sneezing and itching. It also possesses sedative and antiemetic properties, meaning it can help with nausea and vomiting, and promote sleep. Doctors often prescribe it for pre-operative sedation or to manage post-operative nausea.
- Allergic Reactions: Relieves symptoms of allergies, including urticaria (hives).
- Nausea and Vomiting: Controls nausea and vomiting associated with surgery, chemotherapy, or other causes.
- Sedation: Used as a sedative before medical procedures or to aid sleep.
Potential Risks and Side Effects
While Promethazine offers benefits, it’s crucial to be aware of potential side effects. Drowsiness is common, so avoid driving or operating machinery after taking it. Other possible side effects include dry mouth, constipation, and blurred vision. Serious, though rare, reactions might include breathing difficulties or allergic reactions.
- Drowsiness: Expect significant drowsiness; avoid tasks requiring alertness.
- Dry Mouth and Constipation: Increase fluid intake and consider fiber supplements.
- Allergic Reactions: Seek immediate medical attention if you experience hives, swelling, or difficulty breathing.
Drug Interactions
Promethazine interacts with numerous medications, including alcohol and other sedatives. Always inform your doctor of all medications, supplements, and herbal remedies you are taking to avoid dangerous interactions. This includes over-the-counter drugs.
Dosage and Administration
Always follow your doctor’s prescribed dosage and instructions. Never exceed the recommended dose, and never share your medication with others. Improper use can lead to serious health consequences. Dosage varies depending on the specific condition being treated and the patient’s individual needs.

Dosage, Administration, and Patient Considerations
Promethazine dosage varies depending on the indication and patient factors. Always follow your doctor’s instructions. For adults, oral doses typically range from 12.5 to 50 mg every 4 to 6 hours as needed, not to exceed 300 mg daily. Rectal administration may use similar dosages. Children’s dosages are significantly lower and strictly determined by weight and age; consult a pediatrician for precise guidelines.
Administer Promethazine orally with food or milk to minimize stomach upset. Rectal administration requires careful insertion of the suppository according to the provided instructions. Intramuscular or intravenous routes should only be administered by a healthcare professional.
Patients should avoid alcohol and other sedatives while taking Promethazine due to the additive sedative effects. Driving or operating machinery should be avoided as Promethazine can cause drowsiness. Stay hydrated to mitigate potential dry mouth. Report any unusual symptoms, such as allergic reactions (rash, itching, swelling), difficulty breathing, or unusual drowsiness to your doctor immediately. Pregnancy and breastfeeding should be discussed with your doctor before initiating Promethazine treatment. Be aware that Promethazine may interact with other medications, so inform your doctor or pharmacist of all medications you are currently taking, including over-the-counter drugs and herbal supplements. Closely monitor elderly patients for adverse reactions due to increased sensitivity to the drug’s effects.
