Buy Lunox Sleep Aid Tablets

Lunox Sleep Aid Tablets contain diphenhydramine hydrochloride, an antihistamine with sedative properties intended to help you fall asleep. This medicine is only for the relief of temporary insomnia (difficulty sleeping) in adults and adolescents over the age of 16 years old. 


How Lunox Sleep Aid Tablets work 

The active ingredient in Lunox Sleep Aid Tablets is diphenhydramine hydrochloride, an antihistamine which induces drowsiness or sedation, working by reducing the time it should take you to fall asleep and increasing the depth and quality of your sleep. 



Always take this medicine exactly as described in the patient information leaflet or as your doctor or pharmacist has told you. Adults and adolescents over the age of 16 should take two tablets 20 minutes before going to bed. Do not continue to take this medicine for longer than 2 weeks without consulting your doctor. Do not exceed the recommended dose.
