Each 340mg tablet (also known as "Jet-Ease" tablets) contains five homeopathic remedies effective in countering the effects of jet lag. Each pack contains enough tablets for an average round-the-world itinerary (50 hours of flying).
Because of the very small concentration of ingredients in Jet Ease it is safe to use while pregnant when flying.
Directions:
Adults and children over 12 years: One tablet of No Jet Lag should be taken at the time of each take-off, another every two hours in flight, and another after each landing (including at intermediate stops).
During long flights, the two-hour intervals may be extended if the user is sleeping.
Children 2-12 years: One tablet every four hours.  Not recommended for children under 2 years except under medical advice.
