Prednisone helps patients diagnosed with low corticosteroid levels (hen the body does not produce enough of those substances and needs medical support). Prednisone is FDA pregnancy category C - which means it is not known for sure whether this drug will affect the health of an unborn child. Therefore, it's very important that you tell your health care provider about your pregnancy or if you are planning to get regnant during the treatment. Tel your doctor if you are using any medications known to interact with prednisone - especially any of the following ones: seizure medications, oral insulin or diabetes medications, blood thinners, cyclosporine, ketoconazole, diuretic, aspirin, or rifampin. Tell your doctor if your mild side effects you originally had (such as extreme tiredness, increased hair growth, acne, thin, fragile skin, increased perspiration, weak muscles, dizziness, decreased sexual desire, headache, heartburn, insomnia, slowed healing of cuts and bruises, or extreme changes in mood) get severe or do not go away for a long time. You may need a dose adjustment or other changes will need to be made to your treatment schedule.
