12 Common Over-the-Counter Meds with Surprising Side Effects

2. Antihistamines: More Than Just Allergy Relief

Antihistamines are a go-to solution for allergy sufferers, providing relief from symptoms such as sneezing, itching, and runny nose. However, these medications can also produce a range of side effects that may catch users off guard. One of the most common side effects of antihistamines is drowsiness, which can impair your ability to perform tasks that require alertness, such as driving. In addition to drowsiness, antihistamines can also cause dry mouth, blurred vision, and urinary retention. These side effects result from the medication's ability to block certain neurotransmitters in the body, affecting various physiological functions. While newer, non-sedating antihistamines have been developed to minimize drowsiness, they are not entirely free of side effects. Understanding the potential risks associated with antihistamines can help you make informed decisions about managing your allergy symptoms.
