If you will be using this medicine for more than a few weeks, your doctor should check your progress at regular visits.
Check with your doctor:
if signs of a nose, sinus, or throat infection occur.
if your symptoms do not improve within 7 days (for dexamethasone) or within 3 weeks (for beclomethasone, budesonide, flunisolide, fluticasone, mometasone, or triamcinolone).
if your condition gets worse.
When you are being treated with dexamethasone, and after you stop treatment with it, do not have any immunizations (vaccinations) without your doctor's approval. Dexamethasone may lower your body's resistance and there is a chance you may get the infection the immunization is meant to prevent. In addition, other persons living in your household should not take or have recently taken oral polio vaccine since there is a chance they could pass the polio virus on to you. Also, avoid other persons who have taken oral polio vaccine. Don't get close to them, and do not stay in the same room with them for very long. If you cannot take these precautions, you should consider wearing a protective face mask that covers the nose and mouth.
