Phenergan, while effective, can cause side effects. Drowsiness is common; avoid driving or operating machinery until you know how it affects you.
Managing Drowsiness and Other Common Side Effects
- Drowsiness: Take Phenergan at bedtime if possible. Avoid alcohol. Dry mouth: Sip water frequently. Sugar-free gum or candy may help. Constipation: Increase fiber intake and drink plenty of fluids. Consider a stool softener if needed, but consult your doctor or pharmacist. Blurred vision: Avoid tasks requiring sharp vision until the effect subsides. Report persistent blurry vision to your doctor.
Less common, but still possible, side effects include dizziness and low blood pressure. If you experience these, sit or lie down until they pass. Report any concerning side effects to your healthcare provider immediately.
