Dexamethasone is classified as a corticosteroid. It is the synthesized version of naturally occurring hormones produced by the adrenal glands, which help regulate several functions in the body. Corticosteroid medications stop your immune system from overreacting to triggers by blocking specific proteins that cause swelling and inflammation.

Dexamethasone is available in the following forms:

• Oral tablets
  
• Oral solution
  
• Topical creams/ointments
  
• Ophthalmic (eye) drops
  
  

The dosage and frequency of use depend on the condition being treated, its severity, and how you respond to the medication.

Follow your healthcare provider's instructions regarding dosage and schedule. Do not exceed the prescribed dose or frequency of use without consulting your provider.

The time it takes to feel better can vary depending on the condition being treated and individual response to the medication. Some people may start noticing improvements within a few hours, while for others, it might take several days.

Continue using dexamethasone as prescribed, even if you start feeling better. Regular use according to your prescription is crucial for effectively managing your condition.

While dexamethasone is primarily used for treating inflammation, allergic reactions, and certain types of arthritis, healthcare providers may prescribe it off-label for other conditions, such as severe asthma attacks, or as part of chemotherapy treatment.

Discuss any alternative uses of dexamethasone with your healthcare provider.
