Diphenhydramine is an antihistamine that works by blocking the action of histamine, a chemical in the body that causes allergic symptoms such as sneezing, runny nose, and itchy, watery eyes. In addition to treating allergies, diphenhydramine is also used to relieve symptoms of the common cold, such as sneezing, runny nose, and cough.

Diphenhydramine is available in several different forms, including tablets, capsules, and liquids. It's recommended to take it before bedtime as it may cause drowsiness. Depending on what you're using it for, the usual diphenhydramine dose for adults is 25-50 mg every four to six hours. It's important to follow the dosing instructions on the package and not to exceed the recommended dose. Taking more than the recommended dose of diphenhydramine can cause worsening of side effects such as drowsiness, dizziness, and dry mouth.

It's also important to note that diphenhydramine shouldn't be used as a treatment for allergy or sleep problems. If you have ongoing allergies, it's important to identify your allergy triggers and modify your lifestyle. Similarly, if you have ongoing sleep issues, it's important to practice good sleep hygiene.

Diphenhydramine shouldn't be used for chronic sleep problems. If you struggle with persistent sleep issues, speak with your doctor before using sleep aids. Diphenhydramine can be an ideal product for:

  • Jet lag or traveling

  • Sleep disturbances from cold symptoms

  • Occasional sleepless nights or middle of the night awakenings
