FAQs

Yes, diphenhydramine is a type of drowsy antihistamine, but it’s not just used to treat allergies such as hay fever. It’s also used for short-term sleep problems, cough and cold symptoms, in addition to eczema, hives and insect bites and stings.


Like all medicines, diphenhydramine may cause side effects in some people, but these won’t affect everybody. Side effects may include:


  • Drowsiness

  • Dry mouth

  • Dizziness

  • Trouble concentrating

It’s important that you don’t drink alcohol while you’re taking diphenhydramine. This is because the combination of alcohol and diphenhydramine can make you sleep very deeply. This may cause you not to be able to breathe properly and you may have difficulty waking up.

If you’re taking diphenhydramine for short-term insomnia, your tablets will either be 25mg or 50mg in strength. You should take a tablet 20 minutes before you go to bed.
