Taking both a steroid and aspirin can greatly increase your risk of developing a stomach ulcer. If you take this combination of medicines it is commonly advised that you also take a medicine to reduce the acid in your stomach. The aim is to prevent the serious complication of a bleeding stomach ulcer from developing. PPIs are a group (class) of medicines that work on the cells that line the stomach, reducing the production of acid. They include esomeprazole , lansoprazole , omeprazole , pantoprazole and rabeprazole . They come in various different brand names. One of these will normally be advised if you take a steroid and aspirin.
The first-line treatment for arteritis is oral glucocorticoid (steroid) medication, such as prednisone, taken daily for a period of three months.  After this initial phase, the medication may be reduced in dose or frequency, . every other day, if possible.  If the disease worsens with the new treatment schedule, a cytotoxic medication may be given, in addition to the glucocorticoid.  Commonly used cytotoxic agents include azathioprine, methotrexate, or cyclophosphamide.  The dose of glucocorticoid medication may be decreased if response to treatment is good.  This medication may be reduced gradually once the disease becomes inactive, slowly tapering the dose (to allow the body time to adjust) until the medication may be stopped completely.  Conversely, if the disease remains active, the medication will need to be increased.  After six months, if the medication cannot be reduced in frequency to alternate days, or if in 12 months the medications cannot be stopped completely, then treatment is deemed to have failed.
