It’s quite common to find a bottle of Benadryl tucked away in many medicine cabinets. This popular over-the-counter (OTC) antihistamine features diphenhydramine as its active ingredient, effectively alleviating itchiness, seasonal allergies, and minor allergic reactions. While it serves as a handy solution for quick relief, health experts have indicated that prolonged use may lead to some undesirable long-term consequences, including a potential rise in dementia risk.

Investigating the Connection Between OTC Medications and Cognitive Decline

While you might recognize the brand name Benadryl, it actually falls within a broader category known as anticholinergic medications. These drugs work by inhibiting acetylcholine, a crucial neurotransmitter in the body according to the Cleveland Clinic.

Some medications in this category are prescribed for serious health issues such as Parkinson’s disease, overactive bladder, and asthma due to their ability to modulate the nervous system. However, because Benadryl and similar OTC products cause drowsiness, many individuals may resort to them as sleep aids on occasion.

Unfortunately, frequent reliance on medications like Benadryl can heighten risks to long-term cognitive health. A study published in the journal JAMA Internal Medicine analyzed data from over 3,500 older adults, particularly those aged 65 and above. Participants were part of an extensive research initiative called Adult Changes in Thought (ACT), which provided access to their prescription and OTC medication histories over a decade.

Follow-up observations took place for approximately seven years, during which around 800 participants were diagnosed with dementia, according to Harvard Health Press. The findings revealed that those who used anticholinergic medications like Benadryl were at a greater likelihood of experiencing cognitive decline. This risk was particularly pronounced in those consuming these drugs on a regular basis, with evidence suggesting that individuals who used them for three years or longer were 54 percent more likely to develop dementia compared to those with shorter usage of three months or less.

Seniors Face Increased Risks from Anticholinergic Drugs

Apart from the long-term implications for brain health, older adults may also encounter significant short-term risks. According to research from Harvard Health Press, as we age, the production of acetylcholine diminishes. This means that a standard dose can have a more pronounced impact on seniors compared to younger individuals.

Additional physiological changes can further complicate matters. As vital organs function more slowly in older adults, the levels of medication in their system can persist longer. Furthermore, with many older adults taking multiple prescription drugs, there is an increased chance of interactions between those medications and OTC options, as noted by Harvard.

How to Avoid Excessive Usage of Benadryl

The issue of overusing or misusing anticholinergic medications often stems from underlying problems. This is why consulting with a healthcare provider is critical, especially for ongoing issues such as trouble sleeping, as emphasized by Philip Alapat, MD, an assistant professor at Baylor School of Medicine. He shared insights on the school’s website.

“Insomnia for many individuals is usually temporary, often triggered by stress or family challenges. In such cases, it may be reasonable to consider medication to assist with sleep, but it’s vital to consult a doctor to find the most appropriate option,” he advised.

Conclusion

Evidence suggests that anticholinergic medications like Benadryl may raise the risk of developing dementia. A study highlighted that among 3,500 individuals, those who frequently utilized these drugs had a higher likelihood of experiencing cognitive impairments.

To address issues like insomnia without the risks associated with antihistamines, healthcare professionals recommend seeking proper medical guidance.
