It is commonly administered to treat conditions such as arthritis, severe allergic reactions, asthma, and certain types of cancer. This medication is particularly significant in managing acute medical conditions where rapid response is crucial.
Composition and Formulation
Active Ingredient:
- Dexamethasone sodium phosphate (10 mg/mL)
Inactive Ingredients:
- Sodium citrate dihydrate (13.5 mg)
- Benzyl alcohol (10 mg, as a preservative)
- Sodium sulfite (1 mg, as an antioxidant)

Mechanism of Action
Dexamethasone sodium phosphate 10 mg/ml injection solution is a corticosteroid that works by suppressing inflammation and modulating the immune response. Here’s how it works:
Pharmacological Effects:
- Anti-inflammatory: It inhibits the migration of neutrophils and reduces the production of inflammatory mediators, which helps decrease inflammation.
- Immunosuppressive: It suppresses the normal immune response, which is beneficial in conditions where the immune system is overactive.
- Metabolic Effects: It influences carbohydrate, protein, and fat metabolism, which can affect blood sugar levels and fat distribution.
Therapeutic Benefits:
- Reduces Swelling: Effective in reducing swelling and allergic reactions.
- Treats Severe Conditions: Used for severe conditions like asthma, rheumatoid arthritis, and certain cancers.
- Fast Response: The injectable form is used when a rapid response is needed, especially in critical conditions.
This medication is versatile and can be administered via various routes, including intravenous, intramuscular, and intra-articular injections.

Dosage and Administration
Sure, here are the detailed instructions for the proper dosage and administration of dexamethasone sodium phosphate 10 mg/ml injection solution:
Dosage
- Initial Dose: The initial dosage can vary from 0.5 mg/day to 9 mg/day, depending on the specific condition being treated.
- Severe Conditions: For severe conditions, an initial dose of 10 mg IV once, followed by 4 mg IM every 6 hours until the maximal response is noted.
- Adjustment: After 2 to 4 days, the dose should be reduced and then gradually discontinued over a period of 5 to 7 days.
Administration Methods
- Intravenous (IV): Administered directly into a vein. This method is often used for rapid response.
- Intramuscular (IM): Injected into a muscle. This method is used when a slower release of the medication is needed.
- Intra-articular: Injected into a joint space. This is used for treating joint inflammation.
- Intralesional: Injected directly into a lesion. This is used for localized treatment of skin conditions.
- Soft Tissue Injection: Injected into soft tissues for localized treatment of inflammation.
Preparation and Usage
- Preparation: Ensure the solution is clear and free from particles. Do not use if discolored or contains particles.
- Injection: Follow aseptic techniques. Use a new, sterile needle and syringe for each injection.
- Storage: Store at room temperature, away from light and moisture. Do not freeze.
- Disposal: Dispose of needles and syringes in a proper sharps container.
Important Considerations
- Medical Supervision: Always administer under the guidance of a healthcare professional.
- Gradual Reduction: Do not stop the medication abruptly. Gradually reduce the dose to prevent withdrawal symptoms.
- Monitoring: Regularly monitor for side effects and adjust the dosage as needed.
If you have any specific medical conditions or are taking other medications, consult your healthcare provider for personalized instructions.
