Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Diabetes: When mometasone is used over large areas of the body for prolonged periods or under dressings that don't breathe it is possible that enough medication will absorb into the bloodstream to affect blood sugar levels. If you have diabetes, your doctor should closely monitor your condition while you are using mometasone, as it may affect blood sugar control.
Eyes: Use this medication with care on lesions close to the eye. Getting the medication in the eye can increase the risk of increased eye pressure, glaucoma, or cataracts. Report any changes in vision or eye pain to your doctor.
Infections: You may experience an infection in the treated area while using a topical (skin-applied) corticosteroid. If you notice symptoms of a skin infection such as redness, warmth, itching, pus, or swelling, contact your doctor.
Internal absorption: Absorption of topical corticosteroids will increase if large areas are treated or if you use dressings that don't breathe. If you need to use the medication in this way, speak to your doctor about what precautions you should take. This is especially important for infants and children.
Medical treatment: Inform all medical professionals that you see that you have been using topical (skin-applied) corticosteroids.
Poor circulation: If you have poor blood circulation, talk to your doctor about the risks and benefits of using this medication.
Prolonged use: Using topical corticosteroid medication for a long period of time can cause skin to thin or soften or cause stretch marks. Talk to your doctor about how long you should use this medication.
Thinning of skin: Prolonged use of topical corticosteroid products may produce thinning of the skin and tissues under it. If you notice this effect, contact your doctor
Pregnancy: This medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately.
Breast-feeding: It is not known if mometasone passes into breast milk. If you are a breast-feeding mother and are taking this medication, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
Children: Children may be more likely to experience side effects from this medication. The risk of side effects increases when large body areas are treated, when treatment lasts for a long time, and when dressings that don't breathe are used. In these situations, side effects similar to those caused by oral corticosteroids (e.g., growth suppression) may occur. Mometasone is not recommended for use in children less than 18 years of age.
