Difference Between Zyrtec and Zyrtec-D
Zyrtec vs Zyrtec-D
Sometimes, medications are being experimented on and combined together to perform numerous effects in just one tablet. These 2-in-1 or 3-in-1 tablets are useful to prevent drug-drug interactions with other medications and to prevent taking a lot of medications. So by just taking one pill, different symptoms are being treated. Isn’t that cool?
Sometimes when we have allergies, we do not just manifest one symptom. Sometimes it becomes multiple symptoms. So in order for us to counteract these symptoms, we take an antihistamine and another drug for other symptoms. Isn’t that costly and time consuming finding and taking another drug for such symptoms?
