Although your over-the-counter antihistamine medicine may work and help you fall asleep faster, it could cause adverse effects. The McMaster University article noted that antihistamines can affect cognitive functions, such as school or work performance, and an overdose can even lead to death. According to the Baylor College of Medicine, “Antihistamines have side effects that include altered mental status, urinary retention, and dry mouth. While these side effects are generally mild and well tolerated in young patients with no other medical problems, they can pose a risk. , especially for the elderly. “
Also, the antihistamines you are taking to improve your sleep can ultimately have the opposite effect. “The use of antihistamines can lead to sleepwalking and other parasomnias. That can definitely happen with Benadryl as with other hypnotic agents like Ambien,” assistant professor of medicine Phillip alapat, MD, said in an article on the Baylor College of Medicine website. Although antihistamines can help you fall asleep, the overall quality of sleep is often not very good, and the medication has its limits. “Using Benadryl or any antihistamine for sleep has no long-term benefit,” Alapat continued. “Most people develop tolerance very quickly.” And to make sure you’re safe, if you’re taking Tylenol with this, your liver is in danger, experts say.
