Benadryl: Alleviating Cold and Flu Symptoms – Does It Really Work?

When it comes to alleviating cold and flu symptoms, many people turn to over-the-counter medications for relief. One such medication is Benadryl, a popular antihistamine known for its effectiveness in treating allergy symptoms. But does Benadryl really work for cold and flu symptoms? Let’s delve into this topic to provide a comprehensive answer.

What is Benadryl?

Benadryl, also known by its generic name diphenhydramine, is an antihistamine that is commonly used to relieve symptoms of allergies, hay fever, and the common cold. These symptoms may include rash, itching, watery eyes, itchy eyes/nose/throat, cough, runny nose, and sneezing. It works by blocking a certain natural substance (histamine) that your body makes during an allergic reaction. Its drying effects on such symptoms as watery eyes and runny nose are caused by blocking another natural substance made by your body (acetylcholine).

Can Benadryl Alleviate Cold and Flu Symptoms?

While Benadryl is effective in treating allergy symptoms, its efficacy in treating cold and flu symptoms is a subject of debate. This is primarily because cold and flu symptoms are caused by viruses, not histamines. Therefore, while Benadryl may help alleviate some symptoms such as runny nose and sneezing, it may not be effective in treating other symptoms such as body aches, fever, and cough.

What Does the Research Say?

Research on the effectiveness of antihistamines like Benadryl for cold and flu symptoms is mixed. Some studies suggest that antihistamines can provide some relief from cold symptoms, particularly in the early stages of a cold. However, other studies have found no significant benefits. It’s also important to note that antihistamines can cause side effects such as drowsiness and dry mouth, which may not be desirable for some people.

What Do Health Professionals Say?

Many health professionals advise against the use of antihistamines like Benadryl for cold and flu symptoms. They argue that these medications only mask the symptoms and do not treat the underlying cause of the symptoms, which is the virus. Instead, they recommend rest, hydration, and the use of other over-the-counter medications specifically designed to treat cold and flu symptoms.

Conclusion

In conclusion, while Benadryl may provide some relief from certain cold and flu symptoms, it is not a cure-all solution. It’s always best to consult with a healthcare professional before starting any new medication, including over-the-counter drugs like Benadryl. They can provide guidance based on your specific symptoms and overall health condition.
