How to Take Oral Steroids

Current as of October 2026 · Medically reviewed by Dr. Raymond Brown

Quick answer: Oral steroids such as prednisone, methylprednisolone (Medrol) and dexamethasone are pills that calm swelling and inflammation. Take them exactly as your label or dose pack says, in the morning with food, and do not stop a tapering dose early on your own. Short courses are usually well tolerated. Trouble sleeping, mood changes, a bigger appetite, heartburn and higher blood sugar are common and go away after the last dose. Call us for eye pain or a change in vision, signs of an infection or black stools. Call 911 for chest pain, trouble breathing, or thoughts of harming yourself.

What are oral steroids?

Oral steroids (corticosteroids) are prescription pills that reduce inflammation throughout the body. Common examples are prednisone, prednisolone, methylprednisolone (Medrol, often as a 6-day dose pack) and dexamethasone. They are related to cortisol, a hormone your body makes on its own.

They are not the anabolic steroids some people misuse to build muscle. They are also different from a steroid nasal spray or a budesonide sinus rinse, which work mainly where they are applied, with very little reaching the rest of the body.

Why did we prescribe them?

We use short courses, usually a few days to a few weeks, when swelling or inflammation needs to come down quickly. Common reasons include:

  • Nasal polyps. Steroid pills shrink polyps and improve congestion and smell within days, but the benefit fades over the following months. That is why we pair them with longer-term care, such as a steroid spray or rinse, or a biologic medicine.
  • After sinus surgery for nasal polyps, to calm swelling while the sinuses heal.
  • Sudden hearing loss in one ear, ideally started within 2 weeks. See sudden hearing loss in one ear.
  • Other severe swelling, such as a bad allergic flare or swelling in the throat or voice box, when other treatments are not enough.

How do I take them?

  1. Follow your label or dose pack

    Many courses are a taper: the dose goes down a step every day or every few days. If you have a dose pack, such as a Medrol Dosepak, start with day 1 and take the pills in the order printed on the card. Mark off each dose so you do not lose your place.

  2. Take them in the morning, with food

    If your label says once a day, take the whole dose with breakfast. Food protects your stomach, and a morning dose is less likely to keep you awake. If your label spreads the doses through the day, follow the times on the label and take each one with food or a snack.

  3. Finish the course

    Keep taking them exactly as prescribed, even after you feel better. Stopping a higher dose suddenly can cause its own symptoms. If you want or need to stop early, call us first.

  4. If you miss a dose

    Take it as soon as you remember. If it is almost time for your next dose, skip the missed one and go on as scheduled. Do not take two doses to catch up.

  5. Tell us what else you take

    Including other prescriptions, supplements and herbal products. Ask us before taking ibuprofen (Advil, Motrin) or naproxen (Aleve) along with your steroid, especially if you have had a stomach ulcer. Acetaminophen (Tylenol) is fine for aches or pain.

What side effects do steroid pills cause?

Many people have no side effects from a short course of prednisone or another steroid pill. When they happen, they usually go away within a few days after the last dose. What helps:

Side effectWhat helps
Trouble sleepingTake your dose in the morning. Skip caffeine after noon.
Feeling restless, irritable or unusually energeticLet the people you live with know it can happen. Call us if mood changes are severe.
A bigger appetite and some weight gainKeep easy, healthy snacks on hand and go easy on salty foods, which add to fluid buildup.
Heartburn or an upset stomachTake each dose with food. An antacid such as Tums can help.
Higher blood sugarIf you have diabetes, check your blood sugar more often while you take steroids, including after lunch or before dinner: a morning dose raises blood sugar most later in the day. Tell the doctor who manages your diabetes that you started a steroid.
Higher blood pressureIf you check your blood pressure at home, keep checking. Call your doctor if it runs well above your usual numbers.
Easy bruisingThis fades after the course ends.

Are there serious risks?

Serious problems are uncommon with a short course, but they are not zero. In the month after starting a short course of steroid pills, the chance of a serious infection, a blood clot or a broken bone is higher than usual, then falls again. That is why we prescribe them only when the benefit is worth it, at the lowest dose and for the shortest time that works.

Repeated or long courses carry more risk, including thinner bones, cataracts and glaucoma, and changes in the body’s own hormone production. If you have needed more than 2 courses in a year, tell us, so we can talk about other ways to keep the inflammation under control.

Who should talk to us first?

Tell us before you start if you have:

  • Diabetes
  • High blood pressure or heart failure
  • Glaucoma or cataracts
  • Osteoporosis
  • A stomach ulcer or gastritis
  • Depression, bipolar disorder or another mental health condition
  • Tuberculosis, now or in the past, or a current infection
  • Pregnancy, plans to become pregnant, or breastfeeding

Steroids may still be the right choice, but we may change the dose, plan extra checks such as watching your blood sugar, or choose another treatment.

When should I call?

Call us for

  • Eye pain or a change in your vision
  • New pain in a hip or another joint
  • Blood sugar readings well above your usual range
  • Fever or other signs of an infection, or a new rash or skin sores
  • Black or tarry stools, or stomach pain that does not go away
  • Severe weakness, dizziness or fainting, especially after stopping the medicine

Call 911 or go to the ER for

Chest pain, trouble breathing, swelling or pain in one leg with shortness of breath, or a severe change in mood, such as confusion, seeing or hearing things that are not there, or thoughts of harming yourself. You can also call or text 988, the Suicide and Crisis Lifeline.
