Phenergan Products Available
EverydayMeds stocks both Phenergan 25mg tablets (56 tablets) and Phenergan Elixir 5mg/5ml oral solution (100ml). Tablets are convenient for adults requiring sleep support or allergy management, whilst the liquid formulation offers flexible dosing options. Both formulations contain promethazine hydrochloride, a sedating antihistamine that may help with sleep difficulties and allergic reactions.
Understanding Promethazine for Sleep
Promethazine belongs to the first-generation antihistamine class, meaning it crosses the blood-brain barrier and can cause drowsiness. This sedating effect makes it potentially useful for short-term sleep problems. The medication blocks histamine H1 receptors, which naturally promotes sleepiness. For sleep purposes, promethazine is typically taken 30-60 minutes before bedtime.
Dosage Guidelines and Safety
Adult dosing for sleep typically ranges from 25-50mg taken at bedtime. For allergic conditions, doses of 10-25mg may be taken 2-3 times daily or as a single evening dose. Always follow your prescriber's specific instructions. Promethazine should only be used short-term for sleep problems, typically no longer than 7-14 days without medical review.
Who Can Use Promethazine
Promethazine may be suitable for adults experiencing short-term sleep difficulties or those with allergic conditions like hay fever or urticaria. It's particularly helpful when allergies are disrupting sleep patterns. However, it's not suitable for everyone, especially those with certain heart conditions, breathing problems, or those taking specific medications. Our consultation process identifies any contraindications.
Potential Side Effects
Common side effects include drowsiness (which may persist into the next day), dry mouth, blurred vision, and constipation. Some people experience dizziness or confusion. These effects are usually mild and temporary. If you experience severe side effects or signs of allergic reaction, seek immediate medical attention.

Once approved, your promethazine will be dispensed by our registered pharmacy and dispatched using tracked delivery.

Alternative Sleep and Allergy Treatments
EverydayMeds also offers other sleep aids and allergy treatments through our online consultation service.

We provide comprehensive treatment options for both sleep disorders and allergic conditions, ensuring you receive appropriate care.
