Yes, Tavist, which contains the antihistamine clemastine, can cause drowsiness as a side effect. It is commonly used to relieve allergy symptoms, but like many first-generation antihistamines, it can also lead to sedation. It's important to be cautious when taking Tavist, especially if you need to drive or operate heavy machinery.
