Clemastine is a first-generation antihistamine first used in the 1960s. It is intended to treat allergies. Patients who are sixty years old and older may have an increased risk of side effects with this medicine. Breastfeeding women should not take it. Patients who take linezolid or methylene blue should check with their doctor first. This will help them make sure that this antihistamine is safe.

Individuals who have used certain medications within the last two weeks also need to talk to their doctor. Examples include certain Parkinson's disease and depression medications, such as isocarboxazid and selegiline. Taking these medicines together could cause dangerous increases in blood pressure. Side effects of this antihistamine include stomach pain, dizziness, and sleepiness. Patients who notice changes in their balance should let their doctor know right away. Individuals should not use alcohol while taking clemastine.
