Product information
Sominex Tablets help short-term sleeplessness. Each tablet contains 20 mg promethazine, a sedating antihistamine that makes you drowsy so you fall asleep and stay asleep. Use for up to 7 nights only. Adults and those aged 16 years and over.
How to use
Take one tablet at bedtime. You can take it up to one hour after going to bed if sleep is difficult. Do not take more than one tablet in 24 hours. Do not use for more than 7 consecutive nights. The drowsiness can last into the next day, so do not drive or operate machinery and avoid alcohol. Not for those under 16 unless a doctor advises. If sleep problems persist, speak to a clinician.
Main ingredients
Each tablet contains promethazine hydrochloride 20 mg. Excipients include lactose, maize starch, croscarmellose sodium and magnesium stearate.
Side effects and cautions
You may feel morning drowsiness, dry mouth, dizziness, headache, blurred vision or digestive upset. Difficulty passing urine, restlessness, palpitations and low blood pressure can occur. Rarely, rash, photosensitivity or jaundice are reported. Do not use if you are allergic to promethazine or other phenothiazines. Speak to a pharmacist before use if you have asthma, bronchitis, epilepsy, glaucoma, enlarged prostate, heart, liver or kidney problems, or if you take MAOIs or medicines with anticholinergic effects such as tricyclic antidepressants. Avoid alcohol. Stop and seek advice if you get unusual symptoms or persistent next-day sedation.

Frequently Asked Questions
Everything you need to know about ordering from Medicosmetic.
Absolutely. Medicosmetic is a registered, pharmacist-led store. All of our health treatments, medicines, and premium beauty products are sourced directly from verified manufacturers and regulated UK wholesalers. You are getting the exact same genuine products you would find in a high-street pharmacy or premium clinic.
While our premium skincare and General Sales List (GSL) items can be added straight to your cart, certain treatments are classed as Pharmacy-only medicines. To ensure these are safe and appropriate for you, our pharmacists require a quick, confidential online consultation before approving your order.
Yes. We understand that your health and beauty concerns are private. All orders are shipped in plain, unbranded packaging with no indication of the contents or the pharmacy name on the outside of the box.
We offer two fully tracked and secure delivery options. Standard Shipping is £4.99, and Express Shipping is £7.99. Regardless of the delivery speed, all orders are carefully packed and dispatched in plain, discreet packaging to completely protect your privacy.
For safety and hygiene reasons, and in compliance with UK pharmacy regulations, we cannot accept returns on any dispensed medicines (including Pharmacy-only treatments), even if they are unopened. However, unopened and unused beauty and skincare products can be returned within 14 days.
We don't just sell products; we provide care. If you are unsure how to layer a new skincare serum or need advice on taking a medication, our expert pharmacy team is just a message away.
