Avoid grapefruit and grapefruit juice. These can significantly increase the amount of prednisone your body absorbs, potentially leading to increased side effects.
Consume potassium-rich foods. Prednisone can deplete potassium levels. Increase your intake of bananas, potatoes, and leafy green vegetables to counteract this.
Be mindful of sodium intake. Prednisone can cause fluid retention; therefore, reduce processed foods and salty snacks to minimize swelling.
Calcium and Vitamin D
Prednisone can interfere with calcium absorption. Supplementing with calcium and vitamin D, especially if you have a history of low bone density, is advisable. Consult your doctor for recommended dosage.
Alcohol Consumption
Limit alcohol intake. Prednisone combined with alcohol increases the risk of stomach upset and liver damage.
Interactions with Other Medications
Inform your doctor and pharmacist about all medications you take, including over-the-counter drugs and supplements. Certain drugs can interact negatively with prednisone, potentially affecting its effectiveness or increasing side effects.
