Prednisone is a prescription oral corticosteroid medication used to suppress the immune system and reduce inflammation. It belongs to a class of drugs known as glucocorticoids. Prednisone tablets are used to treat a wide range of inflammatory, autoimmune, allergic, and endocrine conditions.
Prednisone works by decreasing inflammation and modifying the body’s immune response. These tablets are used for their anti-inflammatory and immunosuppressive effects and should be taken exactly as prescribed. Prednisone dosage might vary depending on the condition being treated and must be tapered gradually under medical supervision when discontinuing therapy.

Prednisone tablets are a corticosteroid that works by reducing inflammation and suppressing the immune system. It is a synthetic form of hormones naturally produced by the adrenal glands. After you take Prednisone by mouth, it is converted by the liver into its active form, prednisolone.
Prednisolone then:
Because of these effects, Prednisone helps manage conditions involving excessive inflammation or abnormal immune responses, such as asthma, rheumatoid arthritis, lupus, allergic reactions, and certain gastrointestinal or skin disorders.
Prednisone dosage must always be individualized based on disease severity, patient response, and clinical judgment.
| Indication / Use | Monitor blood counts; taper after remission | Notes / Adjustments |
|---|---|---|
| Anti-inflammatory / Immunosuppressive | 5 – 60 mg per day (single or divided) | Adjust based on response; taper gradually when discontinuing |
| Allergic conditions (e.g., asthma, dermatitis) | 5 – 60 mg per day | Short-term use preferred; lowest effective dose recommended |
| Rheumatic disorders (e.g., RA, lupus, ankylosing spondylitis) | 10 – 60 mg per day | Maintenance dose individualized; taper to the lowest effective dose |
| Endocrine disorders (e.g., adrenal insufficiency) | 5 – 60 mg per day | Often combined with mineralocorticoid therapy |
| Hematologic disorders (e.g., ITP, hemolytic anemia) | 15 – 60 mg per day | Monitor blood counts; taper after remission |
| Neoplastic diseases (e.g., leukemia, lymphoma) | 60 – 100 mg per day or higher, depending on treatment protocol | Often part of combination chemotherapy regimens |
| Organ transplantation / Immunosuppression | 20 – 60 mg per day | Used to prevent rejection; taper based on graft stability |
| Gastrointestinal diseases (e.g., ulcerative colitis, Crohn’s) | 20 – 60 mg per day | Short-term induction therapy; taper once remission is achieved |
| Respiratory diseases (e.g., sarcoidosis, aspiration pneumonia) | 20 – 60 mg per day | Duration varies; taper after improvement |
| Ophthalmic diseases (e.g., uveitis, optic neuritis) | 20 – 60 mg per day | Monitor intraocular pressure and vision |
| Dermatologic diseases (e.g., psoriasis, pemphigus) | 20 – 60 mg per day | Use the lowest effective dose; taper gradually |

Prednisone dosing in children must be individualized according to the specific condition being treated, the severity of the disease, and the child’s clinical response. Dosage is typically calculated based on body weight (mg/kg) or body surface area (mg/m²). Because dosing varies widely depending on the indication, pediatric treatment should always be determined and monitored by a qualified healthcare provider.
Acute toxicity from Prednisone is rare. However, prolonged use or higher-than-prescribed doses may increase the risk of serious systemic adverse effects.
Possible Effects of Prednisone Overdose or Excessive Use
If too much Prednisone is taken, contact a healthcare provider right away. In case of Prednisone overdose, seek medical attention or contact a poison control center immediately.
If Prednisone is not suitable, your healthcare provider may recommend other treatments. Some Prednisone alternatives include:
Prednisone may interact with many other medications. Patients should inform their provider about all prescription drugs, OTC medications, and supplements they are taking before starting treatment.
| Drug Class | May reduce Prednisone effectiveness | Interaction Concern |
|---|---|---|
| Nonsteroidal Anti-Inflammatory Drugs (NSAIDs) | Ibuprofen, Naproxen | Increased risk of gastrointestinal irritation, ulcers, and bleeding |
| Anticoagulants | Warfarin | May alter anticoagulant response; increased or decreased bleeding risk |
| Antidiabetic Agents | Insulin, Metformin, Glipizide | Reduced blood sugar control; may cause hyperglycemia |
| CYP3A4 Inhibitors | Ketoconazole, Clarithromycin | May increase Prednisone levels and risk of side effects |
| CYP3A4 Inducers | Rifampin, Phenytoin, Carbamazepine | May reduce Prednisone effectiveness |
| Diuretics (Potassium-depleting) | Furosemide, Hydrochlorothiazide | Increased risk of low potassium (hypokalemia) |
| Cardiac Glycosides | Digoxin | Increased risk of arrhythmias due to electrolyte imbalance |
| Estrogens / Oral Contraceptives | Ethinyl estradiol combinations | May enhance corticosteroid effects |
