4 hours after taking a dose of Reactin, I still have no effect. Can I take a dose of Claritin?

Good evening!Have you just started taking Reactin? If so, you should know that the maximum effectiveness of the product can take from 3 to 5 days to be reached. That being said, taking Reactin and Claritin on the same day is not recommended, especially since Claritin can also take 3-5 days to reach its maximum effectiveness Whichever option you choose, please make sure you take it regularly every day to get the desired effects.As for your symptoms, there are a few options available to relieve them while you wait for your anti-histamine to take effect, in the form of a nasal spray, drops, and/or tablets I invite you to contact your pharmacist, who will be able to suggest a specific product for your symptoms, and which will be compatible with your health condition/medication, if applicable.Hope to see you soon!
