For adults, Phenergan dosage depends heavily on the reason for use and individual factors. Always follow your doctor’s instructions.
Nausea and Vomiting
- Oral: The typical starting dose is 12.5 to 25 mg every 4 to 6 hours, as needed. The maximum daily dose is usually 75 mg. Your doctor might adjust this based on your response. Rectal: A single rectal suppository of 25 mg may be used. Repeat doses are possible, but follow your physician’s guidance. Intramuscular or intravenous: These routes are primarily used in hospital settings and should only be administered by a healthcare professional. Dosages vary depending on the situation.
Sleep Aid
- Oral: A typical dose ranges from 25 to 50 mg at bedtime. This is not a first-line treatment for insomnia; discuss other options with your doctor.
Allergic Reactions
- Phenergan’s role in treating allergic reactions is less common now. Your doctor might prescribe it in specific circumstances, usually in combination with other medications. Dosage will be tailored to your individual need.
