Mometasone (Nasal)

Patients that suffer from both seasonal and year-round allergies like hay fever often find relief with the use of the drug mometasone, a prescription-strength nasal spray; this medication is also used to treat adult patients who suffer from nasal polyps.


The drug mometasone is a prescription-strength medication used in the treatment of rhinitis. It is effective in minimizing the symptoms associated with both allergic rhinitis (or hay fever) and seasonal allergies. Mometasone can also be used by adults who suffer from nasal polyps.

This corticosteroid helps the patient's system suppress the release of the substances that can lead to allergic reactions.

Patients who use mometasone for an extended period of time may develop further issues with their noses and should maintain regular visits with the prescribing physician.

Any patient who experiences an allergic reaction from taking mometasone should stop taking the medication immediately and contact their doctor right away.

The spray bottle that contains the mometasone must be kept as clean as possible, and patients are advised to thoroughly wipe the spray tip after each dosage administration.

Patients, especially children, who are taking mometasone should avoid contact or any interaction with people who are suffering from chicken pox or measles. If contact is made with someone with either of these two ailments, contact the prescribing physician right away.

Parents whose children are taking this medication should be aware of the possibility that it may slow growth in developing children and may also cause problems with the adrenal glands. Any concerns about the possible risks that are associated with their child taking this medication should be thoroughly discussed prior to the start of the course of treatment.

Do not alter the way in which mometasone is taken without first discussing with the doctor.

Side Effects

As with many prescription drugs and other medications, mometasone can cause unwanted side effects in addition to the desired outcome of the treatment. Patients are encouraged to understand the different types of side effects and familiarize themselves with those that may require further medical attention. Some symptoms may dissipate on their own and are likely caused by the introduction of mometasone into the patient's system. It is always best practice to confer with one's medical practitioner if any symptoms linger for more than a few days or become worse.

As the body adjusts to the introduction of mometasone into the system, certain side effects may occur that will likely dissipate on their own.

The dosage guidelines that are outlined below represent the typical course of treatment for patients who are using mometasone. Patients are reminded to always follow the prescription instructions provided by their doctors, even if they differ from what follows below.

Mometasone is a prescription medication and even though it comes in a nasal spray format, the dosage guidelines must still be followed. Do not use more than the prescribed amount of mometasone as the absorption of excess medication through the sinus passages can lead to further nondesired symptoms.

Patients are advised to avoid their eye area when using mometasone at it can cause serious harm. If any of this medication comes into contact with the eyes, conduct a thorough eye-rinse and then notify your doctor or pharmacist for further medical advice.

It is not advisable for patients to stop taking this medication without first discussing the changes with their doctors. It is important to continue taking mometasone even if it feels like the rhinitis symptoms have lessened. Some patients report relief in as little as a couple of days, but it does take up to two or more weeks for the medication to work as fully intended. Patients are advised to take the medication for the entire course of treatment as prescribed and not change the way in which they take mometasone without first discussing any alterations with their prescribing physician.

This medication is not advised, nor effective, for the treatment of other nasal issues such as fungal infections, viral, or bacterial infections.

Proper use:

Prior to every dosage administration, it is important to give the bottle a thorough shake in order to prepare the medication for use.

The nasal spray bottle must be primed prior to every first use. Simply continue pumping the spray bottle until a fine mist is emitted; this may take up to 10 pumps. Once the bottle has been primed it is ready for regular use.

If the bottle containing the medication goes unused for a period of a week or longer it will need to be re-primed. This is accomplished by pumping the bottle until two puffs of mist are released.

Prior to administering the mometasone dosage, patients are advised to blow their noses in order to the clear the nasal passageways as much as possible.

Standing or sitting upright, patients will bend their heads forward at a very slight angle, insert the tip of the spray bottle into their nostril without touching the sides of the nose and spray the mometasone mist directly into that nostril. Breath in gently through the nose and then exhale via the mouth.

Repeat the same directions for the other nostril.

Following the administration of the mometasone dosage, patients should next gently but thoroughly wipe the bottle tip with a clean cloth or tissue prior to reapplying the cap of the spray bottle.

Patients are reminded to always follow the dosage instructions that are provided by their physicians in their prescription instructions. Do not change the way that this medication is taken without first consulting with the prescribing physician.

Use in the treatment of seasonal rhinitis and hay fever symptoms:

Children who are at least 12 will likely be prescribed the same dosage amount as that given to adults: two sprays per nostril one time, every day.

In children aged two to 11, one spray per nostril one time, every day.

Any child under the age of two who has been prescribed mometasone will receive their dosage advice from their doctor on a case by case basis.

Taken as a prevention of temporary rhinitis (seasonal allergies):

Children aged 12 and older and adults are typically prescribed a dose of two sprays per nostril one time, every day.

For this ailment, children under the age of 12 will be provided dosage advice by their doctor or pediatrician on a case by case basis.

Dosage amounts for adults treated for nasal polyps:

The typical dosage amount for the treatment of nasal polyps is two sprays in each nostril taken one or two times each day, as directed by their prescribing physician.

Mometasone is not typically prescribed for use in children for the treatment of nasal polyps. Any child who is prescribed this drug will receive their dosage information from their doctor or pediatrician on a case by case basis.

Patients who inadvertently skip a dose should take the missed dose immediately upon the realization that it was missed. However, if it is close in time to the next scheduled dose, the missed dose should be skipped altogether. Patients who have missed a dose and are unsure about what to do should contact their pharmacist or prescribing physician for further instruction.

Major Drug Interactions:

Like many other prescription and non-prescription medications, mometasone is contraindicated for use with certain drugs. The list below highlights the medications for which the potential for significant and potentially harmful side effects is high, and is in no way comprehensive. Patients are reminded to inform their doctors of all medications that they are currently using or have recently stopped using. This includes both prescription and non-prescription drugs, all herbal remedies, and vitamin and mineral supplements.

Patients who are currently taking any of the medications that are contraindicated for use with mometasone may have the drugs switched for another, or the way in which they take one or both of the medications may be changed. Further medical attention may be warranted in instances where there are severe side effects or reactions when the patient begins taking mometasone.

  • Bemiparin
  • Nadroparin
  • Pixantrone

There is an increased likelihood of patients who are currently taking the drug listed below when they begin their course of treatment with mometasone. The way in which they are prescribed to take one or both of the medications may be changed in order to minimize the occurrence of certain unwanted side effects:

  • Ketoconazole

Any patients who regularly consume alcoholic beverages or use tobacco products are encouraged to notify their physicians of such lifestyle habits as they may alter the way that mometasone affects their system. Similarly, prescribing physicians should be informed of all allergies, including reactions to other medications, food, cleaning products, and other solutions, as these allergic reactions can affect the way that mometasone affects the patient.

Patients who are currently being treated for one or more of the medical conditions listed below may experience a negative reaction when treated with mometasone. This drug may worsen the condition or cause other unwanted changes:


Patients who are taking mometasone for an extended period of time may need to undergo regular diagnostic testing such as blood and urine tests. Such testing will allow their doctors to detect any potential issues and manage the effectiveness of the medication. It is advised that all patients keep follow-up appointments and undergo all diagnostic testing as directed by their doctors.

Mometasone has been known to cause an unpleasant and uncomfortable fungal infection known as thrush that can affect both the mouth and the throat. Any white patches that appear in the patient's throat or mouth should be reported to their doctor. Likewise, any difficulty or pain that is experienced when swallowing or eating.

Using the medication mometasone can also increase the likelihood of the patient experiencing nasal issues. The occurrence of nosebleeds without physical injury, bloody mucus, or open sores within the interior of the nostrils should be reported to the prescribing physician immediately.

Allergic reactions can occur in patients who are using mometasone. Potential harmful reactions typically manifest in the occurrence of breathing difficulties, wheezing, and other reactions that resemble an allergy may be a sign of a more serious problem. Patients should stop taking the drug immediately and notify their doctors right away.

When taking mometasone it is important to avoid, as much as possible, any interaction with people who are suffering from either measles or chickenpox. This rule is especially imperative for children who are taking mometasone to follow. Notify the prescribing physician immediately should any interaction occur.

Overuse of mometasone can cause a heightened risk of issues with the adrenal glands. Symptoms of adrenal gland issues include:

  • Darkening of the skin
  • Skin rash
  • Dizziness
  • Mental depression
  • Loss of appetite
  • Unexplained or excessive weight loss
  • Nausea
  • Fainting
  • Unexplained tiredness or weakness
  • Diarrhea

There have been reported incidences where mometasone has caused slower growth in developing children; a concern that should be discussed with the physician or pediatrician prior to beginning the mometasone course of treatment.

Patients who do not experience an improvement in their symptoms after a reasonable number of doses of mometasone should contact their doctor. It is not advisable to change the amount or the way that mometasone is taken without medical approval.

While taking mometasone patients should not begin treatment with another medication without first consulting their physician.


It is always best practice to store all medications in the original packaging. Mometasone should be stored at room temperature in a low-moisture environment. Do not expose the medication to excessive heat or cold. Do not allow this medication to freeze.

Like all medications, mometasone should be stored out of the reach of small children and pets.

Patients who have any unused, excess, or expired medication at the conclusion of their course of treatment should dispose of it in a safe and appropriate manner.

This medication must be disposed of after 120 doses (sprays) have been dispensed. Keep a record of the number of sprays that are administered and discard the spray bottle after 120. This remains the procedure even in the event that there is medication remaining.
