Momenex – Mometasone Furoate Uses, Dose And Side Effects


Momenex 50micrograms/dose nasal spray, suspension Mometasone furoate as a monohydrate

What Momenex Is And What It Is Used For

Momenex spray contains mometasone furoate, which belongs to a group of medicines called corticosteroids.

When mometasone furoate is sprayed into the nose, it can help relieve 

  • Inflammation 
    • Swelling and irritation of the nose
  • Sneezing
  • Itching
  • Nasal congestion, or runny nose
  • Hay fever
  • Perennial rhinitis

Monex is used to treat the symptoms of hay fever (also called seasonal allergic rhinitis ) and inflammation of the nose caused by allergies (also called perennial rhinitis ) in adults and children 3 years and older.

Hay fever, which occurs at certain times of the year, is an allergic reaction caused by

  • Inhaling pollen from trees
  • Grass
  • Weeds
  • Mold
  • Fungal spores

Perennial rhinitis occurs throughout the year and the symptoms can be caused by a sensitivity to a variety of things. 

House dust mites

  • Animal hair
    • Skin deposits
  • Feathers
  • Certain foods

Monex reduces

  • Swelling and irritation in the nose and thus relieves
    • Sneezing
    • Itching
    • Nasal congestion
    • Runny nose caused by hay fever or perennial rhinitis

Nasal polyps

Monex is used to treat nasal polyps in adults 18 years and older.

Nasal polyps are small growths on the mucous membrane inside the nose and usually affect both nostrils. Monex reduces inflammation in the nose, which means that the polyps gradually shrink and thus reduces a stuffy feeling in the nose that can make it difficult to breathe through the nose.

How To Use Momenex

Momenex nasal spray dosage

Always use this medicine exactly as your doctor or pharmacist has told you. Ask your doctor or pharmacist if you are unsure. Do not use a larger dose or use the spray more often or for longer than your doctor prescribes.

How to prepare your nasal spray before use

Momenex spray has a plastic cover that protects the spout and keeps it clean. Remember to remove the plastic cover before using the spray and to put it back after use.

If you are using the spray for the first time, you must prepare the bottle by pumping the spray 7 times until a fine spray shower is obtained:

  1. Gently shake the bottle and remove the plastic cover.
  2. Place the index finger and middle finger on opposite sides of the spout and thumb under the bottle. Do not make holes in the spout.
  3. Turn the spout away from you and then press down with your fingers to pump the spray 7 times until a fine spray shower is obtained.

If you have not used the spray for seven days or longer, you should prepare the bottle again by pumping the spray twice.

Use of the Momenex nasal spray.

  1. Shake the nasal spray and remove the plastic cover.
  2. Cheat carefully.
  3. Hold one nostril and insert the spout into the other nostril. Bend your head slightly forward and hold the bottle upright.
  4. Inhale slowly and gently through your nose while pressing down ONCE with your fingers.
  5. Exhale through the mouth.
  6. Repeat steps 4 and 5 to inject a second spray into the same nostril, depending on the dose you have.
  7. Repeat steps 3-6 for the other nostril.
  8. After using the spray, wipe the pipe thoroughly with a clean handkerchief or soft paper and put the plastic cover back on.

Cleaning the nasal spray

It is important to clean your nasal spray regularly, otherwise, it may not work properly.

  • Clean the spout and plastic cover once a week with lukewarm water and allow to dry at room temperature.
  • Do not try to clean the spout by inserting a needle or other sharp object as the spout will be damaged, which means that you will not receive the correct Momenex nasal spray dosage.
  • Put the spout back on the bottle and put on the plastic cover.
  • The spray will need to be pushed back on with 2 sprays the first time it is used after cleaning.
