RespiratoryCorticosteroidsAnti-InflammatoryImmunosuppressants

Drug Class

Systemic Corticosteroid (Intermediate-Acting Glucocorticoid)

Pregnancy

Category C — Animal reproduction studies have shown teratogenic effects (cleft palate). First-trimester exposure has been associated with a small increased risk of oral clefts in some human studies. Prolonged or high-dose use late in pregnancy may suppress neonatal adrenal function. Use during pregnancy when clearly needed, at the lowest effective dose.

Available Forms

Oral tablet (1 mg, 2.5 mg, 5 mg, 10 mg, 20 mg, 50 mg), Oral delayed-release tablet — Rayos (1 mg, 2 mg, 5 mg), Oral solution (5 mg/5 mL), Oral concentrate solution (5 mg/mL)

What It's Used For

is prescribed to treat:

Inflammation, allergies, asthma, and autoimmune conditions • Various related conditions in the respiratory category • Associated symptoms and complications

It is an important medication that helps manage these conditions effectively.

Dosage Quick Reference

These are general dosage guidelines. Your doctor will determine the appropriate dose for your specific situation.

ConditionStarting DoseMaintenance Dose
Acute asthma exacerbation (adult)40–60 mg PO once daily for 5–7 daysNo taper needed if course <= 7 days
COPD exacerbation40 mg PO once daily for 5 daysNo taper needed
Acute gout flare30–40 mg PO once dailyTaper over 7–10 days
Polymyalgia rheumatica12.5–25 mg PO once dailyTaper slowly to 5–10 mg/day; total course often 12–24 months
Giant cell arteritis40–60 mg PO once dailySlow taper guided by symptoms and ESR/CRP
Severe poison ivy / contact dermatitis40–60 mg PO once dailyTaper over 14–21 days

Side Effects

Common side effects may include:

Nausea or stomach upset • Headache • Dizziness or lightheadedness • Fatigue or tiredness • Mild rash or itching

Serious side effects (seek immediate medical attention):

• Severe allergic reactions (rash, hives, swelling, difficulty breathing) • Unusual bleeding or bruising • Severe stomach pain • Signs of liver problems (yellowing of skin/eyes, dark urine) • Chest pain or irregular heartbeat • Severe dizziness or fainting • Signs of serious adverse effects

Drug Interactions

Prednisone has wide-ranging effects on metabolism and immune function, leading to many clinically relevant drug interactions.

  • NSAIDs (e.g., ibuprofen, naproxen, aspirin): Substantially increase the risk of gastric ulcers and GI bleeding. Avoid combination when possible; consider a PPI for gastroprotection if both are needed.
  • Anticoagulants (warfarin, DOACs): Variable effects on INR and additive bleeding risk through GI mucosal injury. Monitor INR more frequently after starting or stopping prednisone.
  • CYP3A4 inducers (rifampin, phenytoin, carbamazepine, phenobarbital): Accelerate prednisone metabolism, reducing effectiveness. Higher prednisone doses may be needed.
  • CYP3A4 inhibitors (ketoconazole, ritonavir, clarithromycin): Increase prednisone exposure and risk of corticosteroid side effects. Monitor for excess effect.
  • Antidiabetic agents (insulin, metformin, sulfonylureas): Prednisone causes insulin resistance and hyperglycemia. Diabetic patients usually need increased antidiabetic doses during steroid therapy and reductions during the taper.
  • Live vaccines (MMR, varicella, zoster live, intranasal influenza, yellow fever): Generally contraindicated when prednisone exceeds 20 mg/day for 2 weeks or longer because of suppressed vaccine response and infection risk. Inactivated vaccines remain appropriate.
  • Loop and thiazide diuretics: Additive potassium loss; monitor serum potassium during prolonged combined use.

Frequently Asked Questions

Long-term or high-dose prednisone suppresses your adrenal glands' production of cortisol. Stopping abruptly can leave you without enough cortisol to handle stress, leading to fatigue, low blood pressure, nausea, and rarely adrenal crisis. Courses longer than 2 to 3 weeks generally require a gradual taper to allow your adrenal glands to resume normal function.
Even short courses commonly cause increased appetite, mood changes (irritability, anxiety, insomnia), elevated blood sugar, fluid retention, and stomach upset. Patients with diabetes often see significant blood-glucose elevations. These effects usually resolve within days to weeks of stopping the medication.
Glucocorticoids cause rapid bone loss, particularly in the first 3 to 6 months, by reducing bone formation and increasing resorption. Patients on doses of 5 mg/day or higher for 3 months or longer should have a bone density scan and may need calcium, vitamin D, and a bisphosphonate for osteoporosis prevention.
Cortisol naturally peaks in the early morning. Taking prednisone in the morning aligns with this rhythm, reduces suppression of your own adrenal axis, and lowers the risk of insomnia. Evening doses of corticosteroids more strongly suppress nighttime cortisol production and frequently disrupt sleep.
Yes. Ideally, complete inactivated vaccinations (influenza, pneumococcal, shingles recombinant, hepatitis B) and any indicated live vaccines at least 4 weeks before starting high-dose corticosteroids. Once on doses above 20 mg/day for 2 weeks or longer, live vaccines are generally contraindicated and inactivated vaccines may produce weaker responses.

Questions to Ask Your Doctor

Consider discussing these topics at your next appointment:

  • How long will I need prednisone, and what is the plan to taper it?
  • How will my blood sugar, blood pressure, and bone health be monitored during treatment?
  • Should I take a stomach-protecting medication or calcium and vitamin D while on prednisone?
  • Are my vaccinations up to date, and are there any I should receive before starting?
  • What signs of side effects or adrenal insufficiency should prompt me to call you?
