I used this antihistamine syrup under my doctor’s guidance to help manage allergy-related discomfort. It helped ease my symptoms and made me feel more relaxed at night. I appreciated that it worked gently, but I was also careful about the drowsiness it caused. Overall, it was helpful for short-term relief when used exactly as prescribed by my healthcare provider.
