Prednisone is intended for patients who have low corticosteroid levels. However, your health care provider may prescribe this drug if you have normal levels of corticosteroids and have been diagnosed with severe allergic reactions, some types of arthritis, lupus, multiple sclerosis and a number of conditions that can affect your eyes, skin, blood and kidneys. If you have to take prednisone for a long time to maintain the sufficient level of natural steroids make sure you do not stop the treatment suddenly as your body may not be able to function properly. If you stop anyway you may experience such symptoms as weakness, extreme tiredness, weight loss, sores in the mouth, salt carvings, and upset stomach. If you are taking any drugs but have trouble remembering their names, bring a list of them to the appointment and show it to your health care provider before asking for a prescription. Some of the drugs mentioned below, for example, must not be combined with prednisone, while other ones can be used together with prednisone only after certain tests to establish how safe it if going to be for your health and wellbeing: lovastatin, sertraline, fluoxetine, clarithromycin, hormonal contraceptives, delavirdine, cyclosporine, carbamazepine, HIV protease inhibitors, aspirin, cimetidine, troleandomycin, medications for diabetes, fluvoxamine, rifampin, diltiazem, verapamil, antifungals, dexamethasone, amiodarone, anticoagulants, and diuretics.
