Key Takeaways

  • Magic mouthwash treats painful, inflamed mouth sores and oral mucositis.
  • It combines several prescription ingredients that ease discomfort and promote healing.
  • There’s no standard set of ingredients. Instead, a doctor or pharmacist recommends a formulation based on the specific symptoms and their severity.
  • Magic mouthwash may be less effective than other mouth rinses. 

What is Magic Mouthwash?

Magic mouthwash is a type of oral rinse. It can relieve the symptoms of mouth sores and soft tissue trauma, such as burns. Doctors commonly prescribe it to help with oral mucositis, a painful side effect of head and neck cancer treatments.1

It’s a prescription mouthwash, and each formulation is different. But it typically contains a combination of active ingredients, including steroids, antihistamines, pain relievers, and antifungals.

It has other names, including Mary’s and Duke’s magic mouthwash.

What’s in Magic Mouthwash?

Magic mouthwash contains various medications and active ingredients in different ratios. If someone has mouth sores, their doctor prescribes a specific ‘secret sauce’ or ‘recipe.’ A pharmacist then custom-makes (compounds) it.

Magic mouthwash usually contains:1

  • Nystatin — a medication that stops fungal growth and treats oral thrush (candidiasis).
  • Steroids — hydrocortisone or dexamethasone, which ease irritation, pain, and inflammation.
  • Diphenhydramine (Benadryl) — an antihistamine that reduces swelling and dries out mouth sores.

Other ingredients may include:

  • Lidocaine — an anesthetic with a numbing effect to relieve pain.
  • Chlorhexidine gluconate — an antiseptic that kills bacteria and reduces inflammation.
  • Antacid — this helps the mouthwash coat the oral cavity. Examples include aluminum hydroxide and magnesium hydroxide.

How to Use Magic Mouthwash

Here are the steps for using magic mouthwash:

  1. Rinse your mouth with water and spit it out.
  2. Pour the prescribed dose of magic mouthwash into a sterile spoon or measuring cup.
  3. Place the mouthwash in your mouth.
  4. Swish the liquid around the mouth for 1 to 2 minutes.
  5. Spit it out, as swallowing can upset the stomach.
  6. Avoid eating or drinking for at least 30 minutes to allow the mouthwash to work.


A doctor will prescribe a specific dosage of magic mouthwash. Your dose may depend on the type of mouthwash and the severity of your pain and mouth sores.

For example, in one specific magic mouthwash formula, a 240ml bottle contains:2

  • 30 milliliters (ml) of nystatin suspension at 100,000 units per ml
  • 60 milligrams hydrocortisone
  • Diphenhydramine HCL syrup to bring the total volume up to 240 ml

You may receive your mouthwash in small, individual dose containers or one large bottle containing multiple doses. The typical dose is around 30 ml.3

Frequency of Use

How frequently you should use the magic mouthwash depends on your doctor’s recommendation. You can use magic mouthwash up to six times daily, usually after meals and before bedtime.4

Depending on how well the mouthwash controls your symptoms, you may need to use it more or less often.

Potential Side Effects

Magic mouthwash is safe for most people. However, it can cause side effects, including:4

  • Dry mouth
  • Irritation
  • Pain
  • Upset stomach
  • Diarrhea
  • Nausea

As with any medication, it can also cause allergic reactions. Report any side effects to your doctor. They can change the dose or recommend another treatment.

Magic Mouthwash Cost and Where to Buy

Magic mouthwash costs depend on several factors, including your location, the pharmacy, and the product’s ingredients. 

On average, expect to pay around $30 to $70 for magic mouthwash. In some cases, you may pay less with health insurance. But check with your insurance provider to check if it’s covered.

Magic mouthwash is prescription-level and is only available at compounding pharmacies, where pharmacists accommodate individuals with specific medication needs. Not all pharmacies compound medications, so ask your healthcare team to recommend a local pharmacy. 

Over-the-Counter (OTC) mouthwash

In some cases, over-the-counter (OTC) mouthwashes may help with a sore mouth. If you’re considering an OTC product, talk to your pharmacist. They will let you know if it’s safe to use with any other medications you’re taking.

How Effective is Magic Mouthwash?

Almost everyone who has radiation for head and neck cancer and 1 in 4 people who have chemotherapy develop oral mucositis. Many people must stop cancer treatment because their mouth problems are so severe.6

This is why there is a desperate need for treatments that relieve pain and inflammation from oral mucositis. Using magic mouthwash is one approach, but the research about its effectiveness is conflicting.

A 2016 randomized, double-blind study compared three types of mouthwash: magic mouthwash, doxepin, and a placebo. Researchers found that magic mouthwash and doxepin reduced radiation-induced oral mucositis pain compared to the placebo. In addition, the participants tolerated the mouthwash well.7

A 2011 study evaluated if two types of mouthwash could prevent oral mucositis in people having head and neck radiation. The first was magic mouthwash plus sucralfate, a medication that treats and prevents intestinal ulcers. The second was benzydamine hydrochloride. The authors reported no differences between the two oral rinses.8

Overall, there isn’t enough evidence to confirm the effectiveness of magic mouthwash. But most people tolerate it well, which may help reduce some symptoms.

Alternative Treatments for Mouth Sores

There are other treatments that doctors may prescribe for mouth sores. They include:9

  • Pink lady —  a combination of magic mouthwash ingredients plus an antacid (Maalox) and lidocaine.
  • Noll’s solution contains diphenhydramine, nystatin, a steroid, and a tetracycline antibiotic.

If you have painful mouth sores, there are other things you can do to ease discomfort. These include:

Furthermore, you can try rinsing your mouth with a saline solution. You can make a saltwater mouth rinse by combining the following:

  • 8 ounces of water
  • 1 teaspoon of salt
  • 2 teaspoons of baking soda

According to some experts, this saltwater rinse can be as effective as magic mouthwash in treating oral mucositis.5

How to Make Magic Mouthwash At Home

Unless your doctor says otherwise, attempting to make magic mouthwash at home isn’t recommended. Your doctor must prescribe magic mouthwash, so you’ll have trouble getting the right ingredients in the proper proportions. The wrong combination of ingredients could do more harm than good. 

Your doctor or dentist may suggest making a non-prescription version called “magic mouthwash lite.” It only includes OTC ingredients, such as diphenhydramine and antacids. Only try this if a healthcare professional provides specific instructions.5
