If you suffer from seasonal allergies, you’ve probably got a love/hate relationship with spring. It’s tough to go outside and smell the roses when you’re snuffy and sneezy. The birds might be singing, but your sinuses are screaming for relief.
Oftentimes, people reach for over-the-counter antihistamines to lessen the severity of their allergic symptoms and they can be effective. These drugs block the chemical histamine which the immune system produces when a person is exposed to an allergen. The production of histamine can cause runny nose, watery eyes, itching, swelling, and other symptoms. While it would make sense to lean on antihistamines to relieve the sniffles, medicines like these can also have negative side effects such as drowsiness, fatigue, headache, and nausea.
