About jet lag and Melatonin

Melatonin 3mg tablets are licensed in the UK to treat and prevent jet lag. Melatonin helps regulate the body's day night rhythm - the body clock. If jet lag symptoms are not improving after 5 days, medical advice should be sought. Drinking alcohol can make jet lag worse.

How many tablets do I need?

A pack of 30 Melatonin 3mg tablets is sufficient to treat between three and six episodes of jet lag, depending whether one or two tablets is taken each day. Maximum of 16 treatments per year.

How to take Melatonin for jet lag

Adults only. At destination take one or two 3mg tablets daily at your usual bed-time. Take two tablets if one does not work. Not to be taken before 8pm or after 4am. Best taken with liquid (not alcohol) preferably on an empty stomach (no food for 2 hours before and after). Forgotten tablets can be taken late, but not after 4am. Do not take double doses.

Taking more than the recommended dose (overdose) is likely to cause drowsiness, headache, dizziness, and nausea. Seek medical advice.

Can anyone take Melatonin?
