Deflazacort is a corticosteroid medicine used to reduce inflammation and suppress the immune system, commonly prescribed for conditions like Duchenne muscular dystrophy, autoimmune disorders, and severe allergies. It helps improve muscle strength and slow disease progression but doesn’t cure the underlying condition. Common side effects include weight gain, increased appetite, puffiness in the face, frequent urination, and sleep issues. People with serious infections, uncontrolled diabetes, eye problems like glaucoma, or a history of stomach ulcers should avoid it unless advised by a doctor. It can interact with many medicines, especially those affecting liver enzymes (like ketoconazole or rifampicin), and grapefruit juice should be avoided as it may increase the drug’s levels in the body, raising the risk of side effects. Always take it exactly as prescribed and never stop suddenly without medical guidance. 

Deflazacort 6 mg is an oral medicine belonging to the category of oral corticosteroids and is used to treat muscle weakness and degeneration related to genetics, also known as Duchenne Muscular Dystrophy (DMD).

Deflazacort works by calming the body’s immune system and reducing inflammation. Once inside the body, it turns into its active form and attaches to special switches called glucocorticoid receptors inside cells. This action slows down the release of chemicals that cause swelling and damage, especially in diseases like Duchenne muscular dystrophy, where muscles weaken over time. By doing this, deflazacort helps protect muscles, improve strength, and delay complications. For patients, it’s not a cure but a helpful tool to keep movement and independence going longer. 

Pediatrics

Deflazacort is not recommended to be used in children under 2 years of age, as it can cause low birth weight, breathing problems, and gasping syndrome. So, meet the doctor in any case of pediatric populations.

Liver Problems

Deflazacort is not recommended to be used in patients having Hepatitis B, as it can worsen the viral conditions and increase the chance of infections in patients. So, meet a doctor before using it. 

Infections

Deflazacort can weaken (suppress) your immune system, and you may get an infection more easily. It is also contraindicated in patients with low vision and low bone density. You may need frequent medical tests and consult doctor frequently 

Avoid consuming grapefruit and grapefruit juice, which may interact with deflazacort and lead to unwanted side effects like allergies and skin rashes. Alcohol and smoking can increase the potential of side effects occurring and worsen the patient’s condition.
