Doctors Weigh In: The Effects of Taking Benadryl Nightly
Many people turn to Benadryl as a quick solution to sleepless nights, thanks to its active ingredient, diphenhydramine, which induces drowsiness. While this over-the-counter antihistamine is commonly used to alleviate allergies and cold symptoms, its sedative effects make it an attractive option for those struggling with insomnia. However, medical experts are cautioning against the habitual use of Benadryl for sleep, as it could lead to several concerning health issues.
One of the most immediate effects of taking Benadryl nightly is daytime drowsiness. “Significant sedation and drowsiness” can persist into the following day, according to James Walker, MD, a physician and medical advisor for Welzo. This lingering sedation can impair normal functioning, making activities like driving or operating machinery particularly dangerous. Poison Control experts warn that Benadryl can “impair your hand-eye coordination and reaction time due to sleepiness,” increasing the likelihood of serious accidents.
Another alarming risk associated with regular Benadryl use is the potential for cognitive decline. Dr. Walker notes that the drug can “impair cognitive function, including memory and attention,” making it difficult to concentrate or perform tasks that require mental alertness. A 2015 study published in JAMA Internal Medicine found that individuals using Benadryl or similar anticholinergic medications for three years or more had a 54% higher risk of developing dementia compared to those who used the medication for less than three months.
The risk of falls also increases with nightly Benadryl use. Dr. Walker explains that the drug can “affect balance and coordination,” which is particularly concerning for older adults. Harvard Medical School has identified Benadryl as one of the medications most likely to raise fall risk, as it suppresses the central nervous system, reducing alertness and slowing reactions. This risk is compounded when Benadryl is combined with other sedatives, such as alcohol.
Additionally, long-term Benadryl use can lead to bladder issues, such as urinary retention. This side effect can be particularly troublesome for individuals with pre-existing urinary problems or prostate enlargement, as noted by Dr. Walker.
For those seeking alternatives to Benadryl for sleep, consulting a healthcare professional is crucial. Dr. Walker advises that the use of any medication for sleep aid should be “temporary and under the guidance of a healthcare professional.” Chronic insomnia should be evaluated to identify underlying causes, and doctors may recommend natural remedies like magnesium or melatonin, or lifestyle changes such as increased physical activity and dietary improvements.
Ultimately, while Benadryl might offer a short-term fix for sleep difficulties, its long-term use carries significant risks. It’s important to explore safer alternatives and address the root causes of insomnia with the help of a healthcare provider.
