Asmanex Uses

Asmanex is a dry powder inhaler that’s used to prevent and manage asthma in adults and children 12 years of age. This medication is a long-acting inhaler, meaning it’s intended as a prophylactic treatment and is not indicated to stop the symptoms of asthma attacks at their onset. Proper use of this medication involves regular, long-term use in order to maintain the symptoms of asthma. Please note that Asmanex is not capable of curing asthma.

How does it work?

The active ingredient used in Asmanex is called Mometasone Furoate, which is a type of drug known as an inhaled corticosteroid (ICS). Corticosteroids are synthetic copies of hormones found naturally in the body. Steroids are used in the immune system to reduce inflammation by inhibiting the chemicals that cause the inflammation response.

The inflamed tissue is an important step in the body’s ability to heal itself from damage or illnesses, as it helps prompt healthy blood flow and increases the presence of white blood cells, which protect vulnerable tissues from viruses or bacterial infection.

Who Should Not Use This Medication?

Do not use this medication if you have a hypersensitivity to mometasone, lactose, or other milk proteins, you should not use this medication. The non-medical ingredient in Asmanex is called lactose anhydrous, which contains trace amounts of milk proteins. Severely lactose intolerant individuals may consider using a different medication under a doctor’s discretion. Call emergency medical services at once if you notice signs of an allergic reaction including skin rashes or hives, swelling of the face, tongue, and throat, and difficulty breathing or swallowing.

If you are suffering from an untreated infection, then you should not use this medication until after the infection is fully treated. This is because corticosteroids affect the immune system in a number of ways, including reducing the activity of white blood cells. Without the protection of white blood cells, the tissues in the area the corticosteroid was administered become more vulnerable to infections from attacking viruses or bacteria. Infections that complicate the use of this drug include bacterial, viral, fungal, or parasitic infections, tuberculosis, herpes simplex infections in the eye, and Upper Respiratory Tract Infections.

Do not, under any circumstance, attempt to stop onset bronchospasms or asthma attacks that cause hyperventilation and difficulty breathing with Asmanex. This medication is not capable of replacing your rescue inhaler. If you find yourself having breathlessness attacks and you do not have your rescue inhaler, you need to call for emergency medical services immediately.

Warnings & Precautions

Asmanex Withdrawal Symptoms
Corticosteroids such as mometasone can cause withdrawal if its use is suddenly stopped without proper medical guidance. Withdrawal symptoms for Asmanex include weakness, fatigue, and loss of appetite, weight loss, nausea, vomiting, diarrhea, abdominal pain, low blood pressure, dizziness, fainting spells, low blood sugar, and menstrual changes.

If you have been taking Asmanex and your rescue inhaler stops being as effective as it used to be for treating asthma attacks, then it may be necessary to stop taking this medication. Talk to your doctor for help gradually decreasing your dose.
