There is no allergy medicine without side effects. All medications, even over-the-counter ones, can cause some side effects, even if they are mild. However, some allergy medicines are less likely to cause drowsiness or other common side effects.
Non-drowsy antihistamines, such as fexofenadine (Allegra Allergy), cetirizine HCl (Zyrtec), levocetirizine (Xyzal), and loratadine (Claritin), are good options if you are looking for an allergy medicine that won't make you feel sleepy. These medications work by blocking histamine, a chemical that is released by your body during an allergic reaction.
While these medications are generally well-tolerated, they can still cause side effects in some people. These may include:
- Dry mouth
- Headache
- Stomach upset
- Dizziness
If you are concerned about side effects, talk to your doctor or pharmacist. They can help you choose the best allergy medicine for your individual needs.
