Benadryl: Questions you may have

Here are some common questions about Benadryl and brief answers to them. If you’d like to know more about these topics, ask your doctor.

Does Benadryl come in a nondrowsy form?

No, Benadryl doesn’t come in a nondrowsy form. In fact, drowsiness is a very common side effect of the drug.

Benadryl belongs to a class of drugs called antihistamines. Certain other antihistamines typically cause less drowsiness than Benadryl does. Examples include loratadine (Claritin) and fexofenadine (Allegra).

If you have bothersome drowsiness with Benadryl, talk with your doctor. They’ll advise whether a different antihistamine can be used to ease the symptoms of your condition. If so, your doctor can suggest which antihistamine you should use.

Will Benadryl make me sleepy?

It’s possible. Sleepiness is a very common side effect of Benadryl.

Benadryl belongs to a class of drugs called antihistamines. Antihistamines typically fall into one of three categories: first-generation, second-generation, or third-generation antihistamines.

Of these, first-generation antihistamines typically cause the most sleepiness. And Benadryl is a first-generation antihistamine.

If you have sleepiness with Benadryl that’s extreme or bothersome, talk with your doctor. They can recommend whether an antihistamine other than Benadryl may ease the symptoms of your condition. Your doctor can advise which antihistamine may be right for you.

Can Benadryl be used for nausea, cough, bee sting, or migraine?

Benadryl isn’t typically used for nausea, cough, or migraine. Your doctor can suggest the best ways to manage these conditions.

However, Benadryl may be used for bee stings. Doctors typically recommend Benadryl to ease symptoms such as pain and itching. These symptoms are possible with a mild reaction to a bee sting. If you have these symptoms with a bee sting, your doctor may suggest you use Benadryl to ease them.

Does Benadryl treat anxiety?

No, Benadryl isn’t used to treat anxiety.

However, a different antihistamine called hydroxyzine (Vistaril) is approved to treat anxiety. (Benadryl is also an antihistamine.)

If you have anxiety, talk with your doctor. They can advise whether hydroxyzine or a different treatment could be used for your condition.

Will I have long-term side effects from Benadryl?

Yes, certain side effects are possible after using Benadryl long term.

For example, long-term use of Benadryl may cause:

  • an increased risk of dementia
  • withdrawal symptoms after the drug is stopped*

However, keep in mind that doctors typically don’t recommend taking Benadryl as a long-term treatment. Instead, they usually advise taking it for a short time to ease symptoms of certain conditions.

If you find you need to take Benadryl often, talk with your doctor. They may suggest other treatments for your condition.

* For details, see “Does stopping Benadryl cause withdrawal symptoms?” directly below.

Does stopping Benadryl cause withdrawal symptoms?

Possibly, but it isn’t known for sure.

There has been at least one report of withdrawal symptoms after long-term use of Benadryl. (Withdrawal symptoms are side effects that can happen after you suddenly stop taking a drug your body has become dependent on.)

Below are a few withdrawal symptoms that were reported after stopping Benadryl:

Keep in mind that doctors typically don’t recommend taking Benadryl as a long-term treatment. Instead, they usually advise taking it for a short time to ease symptoms of certain conditions. Withdrawal symptoms aren’t likely to happen with short-term use of Benadryl.

If you’re taking Benadryl long term, talk with your doctor. They can suggest other treatments for your condition.
