Nasonex is a brand name version of the prescription drug mometasone furoate. Mometasone furoate is a type of corticosteroid that can be used in the treatment of a variety of conditions. In its inhaled form, mometasone is used to combat the effects of seasonal allergies, pet allergies, and others. The side effects of Nasonex mometasone include throat irritation, headache, nausea, and vomiting.
Nasonex is a nasal spray which is typically used once per day with two sprays per nostril. According to the National Health Service of the UK, inhaled mometasone helps to ease inflammation of the nasal passages. It can help to relieve such allergy symptoms as congestion, runny nose, and sneezing. Relief is not instant as it takes days for the medication to begin to take its effect and weeks before it goes into full gear. Nasonex can also be used to treat nasal polyps.
The National Institutes of Health report that the most common side effects of Nasonex mometasone include headache, nausea, vomiting, sore throat, and a cough. In some cases, additional side effects of Nasonex can include irritation of the nasal passages, aches or pain in the joints and muscles, diarrhea, and changes in sense of smell or taste.
Certain side effects of Nasonex are more concerning than others as they may indicate an adverse reaction and in rare cases an allergic reaction. The Mayo Clinic reports that serious side effects include nosebleeds, blood in mucus, fever, chills, chest pain, and listlessness. Symptoms like hives, skin rash, itching, swelling, and difficulty breathing are signs of an allergic reaction. If any of these symptoms develop, seek medical attention immediately. Nasonex has few known interactions with other drugs or supplements, but tell your doctor about any other medications you are taking before using Nasonex.
Additionally, people with certain medical conditions may be given different usage instructions or an alternate treatment altogether. According to the Mayo Clinic, before using Nasonex, the doctor should be made aware of any of the following medical conditions: cataracts, glaucoma, herpes of the eye, any nasal injury or surgery, kidney or liver conditions, tuberculosis, and any type of infection, especially chickenpox or shingles.
