Explanation

Diphenhydramine, a common ingredient in over-the-counter sleep aids, can help people fall asleep. However, using it regularly might not be safe. Research shows that while it can be effective for short-term use, it may cause side effects like dry mouth, dizziness, and confusion, especially in older adults.

Potential Risks

  • Next-Day Drowsiness: After using diphenhydramine at night, some people may feel sleepy or less alert the next day.
  • Side Effects: Regular use can lead to unwanted effects such as dry mouth, dizziness, and confusion.

Recommendations

It's best to use these sleep aids only occasionally and not as a regular solution for sleep problems. If you have ongoing trouble sleeping, talking to a healthcare provider is a good idea. They can help find a safer and more effective way to improve your sleep.
