10 Side Effects of Antihistamines

Side Effect #7: Headaches
One of the most common side effects associated with antihistamines is the classic headache. It can be difficult to assess the real incidence of this side effect, because some of the pathologies which may lead a patient to use antihistamines, may cause a headache as well. That being said it is described to happen in 10 to 15% of patients.
The headache is usually not so intense, it shouldn’t interfere with your day to day activities and goes away fairly quickly (2 hours at most). If you are having constant headaches, you should seek medical attention for further evaluation and diagnosis.
