Does Cetirizine Cause Drowsiness?


Cetirizine is a second-generation antihistamine commonly used to relieve symptoms of allergies, such as hay fever, hives, and allergic rhinitis. One of the advantages of second-generation antihistamines like cetirizine is that they are generally less sedating compared to first-generation antihistamines.

However, while cetirizine is considered non-sedating for many people, it can still cause drowsiness in some individuals. The degree of drowsiness can vary from person to person, and factors such as individual sensitivity, dosage, and interactions with other medications can play a role.

It’s recommended to take cetirizine at bedtime initially to assess its effects on drowsiness. If you find that cetirizine makes you drowsy or affects your ability to perform certain tasks, you may want to avoid activities that require alertness, such as driving or operating heavy machinery, until you understand how the medication affects you.

If you have concerns about the side effects or interactions of cetirizine with other medications you may be taking, it’s always advisable to consult with your healthcare provider. They can provide personalized advice based on your medical history and individual circumstances.
