Mucinex and Benadryl are both popular over-the-counter medications used to treat the symptoms of allergies. While they are similar in that they each offer relief from sneezing, runny nose, itchy eyes, and general congestion, they have some key differences.

Read on to learn more about these two medicines and when to take them for optimal results.

Mucinex

Mucinex is one of the most popular over-the-counter medications for treating allergies. It is a combination allergy medicine that contains both an antihistamine and a decongestant.

The active ingredients in Mucinex are guaifenesin and pseudoephedrine, which help relieve symptoms like a runny nose, sneezing, watery eyes, and coughing.

Guaifenesin is an expectorant that thins the mucus in your lungs, making it easier to cough up, so you can breathe easier. Pseudoephedrine is a type of decongestant that shrinks swollen blood vessels and increases blood flow to the sinuses, helping to relieve pressure and clear up congestion.

Like other allergy medicines, Mucinex comes in several forms: tablets, capsules, syrup, and a liquid.

The recommended daily dosage of Mucinex varies depending on which type of medication you choose: 10-12 mg guaifenesin per tablet/capsule, 15-20 mg guaifenesin per teaspoon of syrup, and 5 mg per tablespoon of liquid.

Benadryl

Benadryl is an antihistamine that is used to treat the symptoms of seasonal allergies and other types of allergies. Benadryl works by blocking certain natural substances produced by the body that can cause allergy symptoms, such as itching, runny nose, watery eyes, sneezing, and trouble sleeping. Benadryl can also be used for other medical conditions such as motion sickness, sleep disorders, and certain types of headaches.

However, the dosage may be different for children depending on their age. It is important to always follow your doctor’s instructions on how to properly take Benadryl.

Difference Between Mucinex and Benadryl

While both Mucinex and Benadryl are used to treat allergies, they work in different ways. Mucinex is a combination allergy medicine that contains both an antihistamine and a decongestant.

Benadryl is an antihistamine that blocks the body’s natural substances that cause allergy symptoms such as itching, runny nose, and sneezing.

Mucinex works by opening inflamed nasal passages and relieving sinus pressure, while Benadryl works by blocking the natural substances that cause allergy symptoms. Both Mucinex and Benadryl are generally safe to take together, but you should always consult your doctor first.

Depending on the condition being treated, your doctor may prescribe an alternative treatment to Mucinex or Benadryl.

When to Take Mucinex

Mucinex is a go-to remedy for many seasonal allergies. It’s also commonly used to treat colds and sore throats. You can use Mucinex as a preventive measure for seasonal allergies, or you can also use it to relieve symptoms that have already started.

  • To prevent seasonal allergies, take 2-3 mg of the guaifenesin component of Mucinex per day from mid-April through mid-September. You can also take a 5 mg dose of pseudoephedrine for one week before allergy season begins.
  • If your allergies are causing a stuffy nose, sneezing, watery eyes, and/or cough, take the recommended doses of guaifenesin and pseudoephedrine in Mucinex to relieve symptoms.
  • If you’ve been diagnosed with a sinus infection, your doctor may prescribe antibiotics. In this case, you should take Mucinex while taking antibiotics to relieve sinus pressure and help thin out the mucus in your nose.
