I had taken Benadryl Allergy medicine for years and was looking for a less expensive option. I relied heavily on the sleep-inducing properties of Benadryl and was hoping for the same effect from Equate Allergy & Sinus Relief Tablets. I was sadly disappointed. During a sever allergy attack, I took two of these tablets and did not experience any relief. Several hours later, according to the instructions, I took two more tablets but did not notice a reduction in my symptoms. I suffer from seasonal allergies as well as some specific ones, including hay fever, animal dander and pollen. I wish that the Equate brand would have worked for me since it is a much less expensive option. I guess you get what you pay for. Effectiveness Did not relieve my allergies or help me sleep. I was still just as congested as before. Ease of Use Directions are clear and easy to follow. Immediacy I never experienced any relief with the Equate brand of allergy medicine.
