This guide explains what to expect, how to ease common effects and which warning signs need a doctor right away.

What Prednisone Treats

Prednisone is a corticosteroid, a man-made version of a hormone your adrenal glands make. MedlinePlus says it treats many conditions by calming swelling and an overactive immune system.

Some types of arthritis
Severe allergic reactions
Lupus and multiple sclerosis
Some lung, skin, eye, kidney and bowel conditions
Low natural corticosteroid levels

Doctors may prescribe a short burst for a few days or longer treatment for chronic conditions. Side effects depend a lot on how long you take it.

Prednisone is widely available as a low-cost generic. Our guide on generic vs brand-name medicines explains how generics work.

Common Prednisone Side Effects

MedlinePlus lists these common side effects. Tell your doctor if any are severe or do not go away.

Side effect	What you may notice
Trouble sleeping	Feeling wired at night
Mood changes	Irritability, highs or lows
Heartburn	Burning in the chest or upset stomach
Headache and dizziness	Mild head pain or light-headedness
Skin changes	Acne, thin skin or slow wound healing
Body changes	Fat shifting to the face or belly
Muscle weakness	Tired or weak muscles
Sweating	More sweating than usual
Hair and cycles	Extra hair growth or irregular periods

Many people also notice a bigger appetite. That can lead to weight gain, especially with longer courses.

How to Feel Better on Prednisone

Take prednisone with food, as MedlinePlus advises, to protect your stomach.
Take it at the same times each day as prescribed.
Ask your doctor whether a morning dose could help you sleep better at night.
Fill your plate with vegetables, fruit and lean protein to manage appetite.
Limit salty and sugary foods, which can add to swelling and weight gain.
Stay active with walks or gentle exercise your doctor approves.

Keep healthy snacks ready, like fruit, yogurt or vegetables with hummus. A bigger appetite is easier to handle when good choices are close at hand.

Quick tip. Set a phone alarm for each dose. Steady timing helps the medicine work and makes tapering easier later.

Sleep and Mood Changes

Prednisone can make you feel restless, energetic or emotional. MedlinePlus lists extreme mood changes and personality changes among its side effects.

Keep a calm bedtime routine and a dark, cool bedroom.
Skip caffeine in the afternoon and evening.
Tell family that mood swings may be from the medicine.
Write down mood changes to share with your doctor.

Call your doctor right away for depression, confusion or losing touch with reality. These are serious side effects, according to MedlinePlus.

Infection Risk

Prednisone calms your immune system, so it can lower your ability to fight infection. MedlinePlus also warns it may hide the usual signs of an infection.

Stay away from people who are sick.
Wash your hands often with soap and water.
Call your doctor right away if someone with chickenpox or measles was near you.
Do not get any vaccines without checking with your doctor first.

The CDC says to scrub hands for at least 20 seconds. Without soap, use a sanitizer with at least 60 percent alcohol.

Bones and Vitamin D

MedlinePlus says prednisone may increase the risk of osteoporosis, a condition that makes bones thin and easier to break. It may also slow growth in children.

The NIH notes that steroids like prednisone can lower blood levels of vitamin D. Vitamin D helps your body use calcium for strong bones.

Ask your doctor whether you need a bone density test.
Eat calcium-rich foods like dairy, fortified plant milks and leafy greens.
Ask whether you need vitamin D or calcium supplements.
Do weight-bearing exercise, like walking, if your doctor approves.

Stopping Prednisone Safely

Never stop prednisone suddenly. Your body makes less of its own steroid hormones while you take it, and it needs time to catch up.

MedlinePlus warns that stopping too fast can cause extreme tiredness, weakness and an upset stomach. Weight loss, skin color changes, mouth sores and salt cravings can also happen.

Your doctor will often lower the dose slowly, called tapering. Follow that schedule exactly, even if you feel fine.

Good to know. Tell any doctor, dentist or surgeon that you take prednisone, especially before surgery or during a serious illness.

Lean protein like fish, beans and eggs	Sugary drinks and sweets
