What is Claritin?

Claritin is an antihistamine used to treat allergy symptoms. It helps with sneezing, itching, and a runny nose. It’s a popular choice since it has a non-drowsy formula. Unlike other antihistamines, it doesn’t make you sleepy or tired.

But this doesn’t mean Claritin can’t cause insomnia. Insomnia is when you struggle to fall asleep or stay asleep. It’s less common than drowsiness, but it still happens to some users.

If you have insomnia after taking Claritin, it’s essential to speak to your healthcare provider. They’ll assess the situation and tell you if it’s okay to keep taking the medication or switch to a different one.
