Can Benadryl Be Used for Anxiety?

Can you use Benadryl for anxiety? That might be a question you have if you are living with anxiety and don't like traditional medications or have not yet visited your doctor. Beyond Benadryl, there are also other over-the-counter (OTC) medications that you might consider using for anxiety.

But the question is—are they safe? Do they work? What are the pros and cons? And, can you use them to supplement other treatments you might receive? Let's consider each of these questions below to help you sort through your options in terms of over-the-counter medication for anxiety.

OTC Medications for Anxiety

First things first—you're probably wondering if over-the-counter medications even work for anxiety? In order to consider this question, first, let's consider the different over-the-counter medications that you might use for anxiety, because Benadryl is only one of many.

Antihistamines and Other Sedatives

Antihistamines such as Benadryl are used to manage allergic reactions, but they can also cause sedation as a side effect. Some people take Benadryl for anxiety because of the calming and sleep-inducing effects that it can have. However, these effects are less than you would see for prescription sedatives such as benzodiazepines.

Benadryl takes about 15 to 30 minutes to start working and its peak effect happens around 2 to 4 hours. An adult dose to obtain sedating effects is between 25 and 50 milligrams.

In addition to the sedating effects of antihistamines, other over-the-counter drugs can induce sedation and drowsiness, most notably those marketed as muscle relaxers or sleep medications.

Herbal Remedies

Herbal remedies, such as kava kava, l-theanine, 5-hydroxy-tryptophan (5-HTP), passionflower, valerian, lavender, lemon balm, skullcap, and chamomile, are generally found in the form of teas, sprays, pills, oils, or tinctures. Herbal remedies can also have calming effects, but these are generally mild.

These remedies are not strong enough to effectively treat acute anxiety symptoms. Herbal remedies are best used to help you calm down or fall asleep, rather than as a first-line defense for intense anxiety.

Cough and Cold Medicines and Painkillers

Various painkillers may act on parts of the brain involved in the experience of emotional pain. In fact, one study from the University of British Columbia concluded that over-the-counter medication such as Tylenol had an impact on emotional distress and anxiety triggers.

Vitamins and Minerals

Most people know that vitamins and minerals are important for physical health, but can taking them reduce anxiety? Unfortunately, unless you have a deficiency in a particular vitamin or mineral (determined by your doctor), it's unlikely that taking vitamin or mineral supplements will reduce anxiety. That being said, there is no harm in taking a daily multivitamin to support your overall health.

Safety of Over-the-Counter Medicines

The safety of over-the-counter medications for anxiety generally depends on what you are purchasing. Most over-the-counter medications that you might take for anxiety, such as antihistamines, while approved by the Food and Drug Administration (FDA) as safe, have not been approved for alleviating symptoms of anxiety. They aren't meant to be taken long term, they carry risks for side effects and there is potential for abuse.

Herbal supplements are not regulated in the same way as medications and long-term studies on efficacy and safety are lacking. However, most supplements are safe to use as their effects are mild.

For some supplements, such as kava kava, there is concern over serious side effects such as liver damage. It is important to be aware of potential side effects of herbal supplements and to contact your doctor if you experience any of these. Always tell your doctor what supplements you are taking, as there is always a risk of interaction among supplements or with other medicines you might be taking.

Pros and Cons of OTC Medicines for Anxiety

  • Risk of dependence and withdrawal is less than for prescription sedatives

  • May aid sleep and relaxation

  • Easy and inexpensive to obtain

  • Potentially useful for short-term episodes of anxiety

  • Potentially useful if you are against taking traditional medications for anxiety

  • May be helpful to supplement other treatments such as psychotherapy

  • Potential to cause drowsiness during the day

  • Not effective for severe anxiety

  • Not approved by FDA for treating anxiety, or not regulated by FDA

  • Not meant for long-term use for anxiety

  • Potential side effects

OTCs to Supplement Other Anxiety Treatments

Other types of treatments you might be receiving for anxiety might include talk therapy (e.g., cognitive-behavioral therapy, mindfulness, and acceptance-based therapy) and prescription medications (e.g., benzodiazepines or selective serotonin reuptake inhibitors (SSRIs).

You can theoretically use over-the-counter medications for anxiety while receiving other treatments. But first, ask yourself why you want to do so. Perhaps you are receiving therapy but wary of taking a prescription medication. Or you are taking a prescription medication, but are waiting for it to take effect and want short-term relief.

Maybe you are using an alternative treatment and want to add in an over-the-counter medication. In all these cases, it's likely that you will be better off consulting with your doctor. They can help you determine the best course of treatment for you. If you are only receiving talk therapy and want a short-term solution to mild anxiety that bothers you mostly at night, then an over-the-counter solution might be helpful.

Never combine an over-the-counter medication with prescription medication for anxiety without the advice of your doctor, as there is the possibility of medication interaction.

Who Should Use Over-the-Counter Medications?

A study of 690 German pharmacists determined that people seeking over-the-counter treatments for anxiety and depression:

  • Were more likely to be younger
  • Had a shorter duration of illness
  • Had less severe symptoms
  • Were skeptical about psychopharmacology

However, the study wondered whether this was a logical or cost-effective solution to these problems. Most people purchasing over-the-counter treatments for anxiety would probably benefit from professional help and talk therapy or prescribed medication. The exception might be for cases of very mild anxiety that seem to be helped by herbal remedies that offer relaxation at bedtime.

A Word From Verywell

While it may seem easy or fast to run to the drugstore and pick up an antihistamine or painkiller to knock yourself out every time your anxiety takes hold, there are many risks associated with this practice. The outcome is not likely to be as good as if you received proper help.
