Dehydration would certainly only happen if such a medication gotten rid of too much fluid from the body. Speak to your doctor if you"re concerned.

Medications the dry you out—antihistamines—cause that side effect due to the fact that they block a certain neurotransmitter in the brain, Jennings says. 

Many patients endure drying next effects since they are taking too plenty of antihistamines. "For example, if someone is acquisition a everyday antihistamine for allergy symptoms and currently suffering from cold/flu symptoms, they might (not always knowingly) take a multi-symptoms product that outcomes in a duplication the antihistamine," Jennings says.

Jennings offers the example of someone acquisition a day-to-day antihistamine to fight seasonal allergies that then comes down with the common cold. 

If they proceed to take their everyday allergy medication and also introduce a product like NyQuil for overnight cold relief, they space doubling increase on antihistamines and are an ext likely to experience too much dryness. <6> plenty of consumers aren"t aware of what"s in their medications or just how their medications may interact, Jennings adds.
