Side effects: Jet lag tablets may cause mild side effects such as drowsiness, headache, dizziness, nausea, vivid dreams, or feeling less alert the next day.
Additional precautions: Avoid driving, operating machinery, or drinking alcohol if the tablets make you feel sleepy or less alert. Seek medical advice if you experience severe drowsiness, confusion, mood changes, allergic symptoms, or if your sleep problems continue after travel.
Risks caused by jet lag: Jet lag can happen when travelling across multiple time zones and your body clock becomes out of sync with the local time. Symptoms may include tiredness, poor sleep, difficulty concentrating, irritability, headache, and digestive upset.
