I'm on a Flexeril prescription but my allergies are horrible and I'd like to take a Benadryl too. Is it okay to take these drugs together?
One of the best places to go for questions like this is to call your local pharmacist. They're often able to answer drug interaction questions more quickly than we can.
My research has revealed that these drugs have a moderate interaction with one another, which means that they can make one another more powerful. It may make drowsiness, dry mouth, and other side effects of both medications more pronounced. If you're taking a standard dose, however, you shouldn't experience anything negative.
