Complete Phenergan Usage and Safety Checklist
Pre-Treatment Checklist
Before starting Phenergan 25mg tablets or elixir, ensure you've completed these essential checks. Verify you're not allergic to promethazine or phenothiazines. Check current medications for potential interactions, particularly with other sedating drugs, alcohol, or MAO inhibitors. Confirm you don't have contraindicated conditions such as severe heart problems, breathing difficulties, or enlarged prostate issues.
Dosage and Administration Guide
For allergic conditions, adults typically take 25mg at bedtime or 10-20mg two to three times daily. When using for sleep difficulties, take 25-50mg at bedtime for short-term use only. For motion sickness prevention, take 25mg the evening before travel, followed by 25mg on the morning of departure. EverydayMeds stocks both Phenergan 25mg tablets (56-tablet pack) and Phenergan elixir 5mg/5ml solution (100ml bottle) to suit different preferences.
Safety and Monitoring Checklist
Always take with food to reduce stomach upset. Avoid alcohol whilst using promethazine as this increases drowsiness and can be dangerous. Don't drive or operate machinery for at least 8 hours after taking, as sedation can persist. Monitor for common side effects including drowsiness, dry mouth, blurred vision, and constipation. Contact your healthcare provider if you experience severe side effects such as muscle stiffness, tremors, or breathing difficulties.
Storage and Usage Guidelines
Store Phenergan tablets and elixir below 25°C in original packaging, away from children. Check expiry dates before use and dispose of expired medication safely. For liquid formulations, shake well before measuring doses. Use the measuring spoon provided with elixir rather than household teaspoons for accuracy. Don't exceed recommended doses or use for longer than advised without medical supervision.
