Sominex – A Simple Guide to Temporary Sleep Problems
A good night’s sleep is essential for your energy, concentration and routine during the day. But sometimes stress, disruptions to routine, travel or other temporary problems can make it difficult to fall asleep or stay asleep. Sominex contains promethazine hydrochloride, an antihistamine with sedative properties, and is a sleep aid for nighttime use. Sominex tablets contain promethazine hydrochloride 20 mg in the UK.
What Is Sominex?
Sominex is a drug for temporary disturbances of sleep. It can help a person who has trouble sleeping or staying asleep because of a change in their normal routine. Promethazine is a sedating medication and can make you sleepy.
Sominex, therefore, is intended for short-term rather than long-term treatment of chronic insomnia. If sleep problems do not improve or get worse after seven days, speak to a doctor, the patient leaflet says.
How Sominex Works ?
Sominex contains promethazine hydrochloride, which belongs to a group of medicines called antihistamines. Antihistamines are a common treatment for allergies, but some can cause drowsiness as well. Sominex is a sedative that makes you sleep at nite.
So it could be useful for those who have occasional trouble getting to sleep. Do not use Sominex unless it is directed on the product label or by your healthcare professional.
How to use Sominex
The current UK patient information recommends that adults, older people and children over 16 should take one tablet at nite. When sleep is difficult to obtain it can be taken up to 1 hour after going to bed. Do not take Sominex for more than 7 days unless directed by a health care professional.
Do not go beyond the recommended dose. Too much of it can cause severe symptoms, such as seizures, a loss of consciousness, an irregular heartbeat or trouble breathing.
