Combining ranitidine and prednisone can increase your risk of certain side effects. Pay close attention to your body and report any concerns to your doctor immediately.
Gastrointestinal Issues
Prednisone commonly causes heartburn and indigestion. Ranitidine, while used to treat these, may not fully counteract the prednisone’s effect, particularly at higher prednisone doses. You might experience increased stomach upset, nausea, or diarrhea.
Increased Risk of Infections
Prednisone weakens your immune system, making you more susceptible to infections. This risk is amplified by long-term use. Monitor yourself for any signs of illness and contact your doctor promptly if you become unwell.
Other Potential Side Effects
Both medications can cause headaches. Prednisone can also lead to increased blood sugar, weight gain, mood changes (including irritability or anxiety), and insomnia. Ranitidine, less frequently, can cause constipation or dizziness.
