Mometasone furoate increased chromosomal aberrations in an in vitro Chinese hamster ovary-cell assay, but did not increase chromosomal aberrations in an in vitro Chinese hamster lung cell assay. Mometasone furoate was not mutagenic in the Ames test or mouse- lymphoma assay, and was not clastogenic in an in vivo mouse micronucleus assay and a rat bone marrow chromosomal aberration assay or a mouse male germ -cell chromosomal aberration assay. Mometasone furoate also did not induce unscheduled DNA synthesis in vivo in rat hepatocytes.

The regular use of a non-medicated saline nasal spray is very beneficial for relieving nasal congestion associated with rhinitis. Saline sprays help to flush away problem allergens and irritants from within the nose, and keep the nose clear by loosening and thinning mucous. Saline sprays are gentle, and soothe and moisturise inflamed nasal membranes. The use of a saline solution to clear a congested nose prior to using medicated nasal sprays, is sometimes recommended to enhance the absorption and effectiveness of medicated sprays (Care Pharmaceuticals, 2015).

Certain drugs such as troleandomycin (TAO), erythromycin ( Ery-Tab , EryPed 200), and clarithromycin ( Biaxin ) and ketoconazole ( Nizoral ) can reduce the ability of the liver to metabolize (breakdown) corticosteroids and this may lead to an increase in the levels and side effects of corticosteroids in the body. On the other hand, phenobarbital, ephedrine , phenytoin ( Dilantin ), and rifampin ( Rifadin , Rimactane ) may reduce the blood levels of corticosteroids by increasing the breakdown of corticosteroids by the liver. This may necessitate an increase of corticosteroid dose when they are used in combination with these drugs.
