For people with certain health conditions
For people with infections. Dexamethazon may make a systemic fungal infection worse. (Systemic means it affects the whole body, not just one part.) This drug shouldn’t be used if you’re taking medication to treat a systemic fungal infection. Also, Dexamethazon may hide the signs of a non-fungal infection.
For people with congestive heart failure. Dexamethazon can increase sodium levels, edema (swelling), and potassium loss. This can make your heart failure worse. Before taking this drug, talk to your doctor about whether it’s safe for you.
For people with high blood pressure. Dexamethazon can increase sodium levels and edema (swelling). This can increase your blood pressure. Before taking this drug, talk to your doctor about whether it’s safe for you.

For people with osteoporosis. Dexamethazon decreases bone formation. It also increases bone resorption (breakdown of bone). As a result, it raises the risk of osteoporosis (bone thinning). The risk is higher for people already at an increased risk of osteoporosis. These include postmenopausal women.
For people with hyperthyroidism. This drug is removed from the body more quickly than normal. Your doctor may adjust your dose of this drug based on your condition.

For people with diabetes. Dexamethazon can increase blood sugar levels. As a result, your doctor may change the dose of your antidiabetic drugs.
For people with myasthenia gravis (MG). If you have MG, using Dexamethazon with certain drugs used to treat Alzheimer’s disease can cause severe weakness.
