Warning!
Do not use this medicine for longer than seven days without seeking medical advice from your doctor.
This medicine may cause drowsiness that can last up to 12 hours. If affected you should not perform potentially hazardous tasks such as driving or operating machinery. You should avoid drinking alcohol when taking this medicine.
This medicine may interfere with some pregnancy tests, causing false negative or false positive results.
If you are due to have any skin prick tests to diagnose allergies you should stop taking this medicine at least 72 hours before the tests. This is because antihistamines can prevent or lessen the skin reactions that indicate an allergy, and so can make the test results unreliable.
