Prednisone is a medication that treats conditions like asthma, allergic reactions, arthritis, inflammatory bowel disease and adrenal, blood or bone marrow conditions. It decreases inflammation, slows an overactive immune system or replaces cortisol.
Steroid drugs, such as prednisone, work by lowering the activity of the immune system. The immune system is your body's defense system. Steroids work by slowing your body's response to disease or injury. Prednisone can help lower certain immune-related symptoms, including inflammation and swelling.
Prednisone is used to treat conditions such as arthritis, blood disorders, breathing problems, severe allergies, skin diseases, cancer, eye problems, and immune system disorders. Prednisone belongs to a class of drugs known as corticosteroids.
Taking prednisone can increase the chances of developing mild, serious or life-threatening infections. Larger doses increase the risk, especially doses for immunosuppression. Older age and taking other medications that also suppress the immune system increases the risks. Doses of 10 mg or lower pose the least risk.
Fluid retention is one of prednisone's most famous side effects. “'Moon face' is common, which is swelling in the face that can occur after you've been on steroids for a long time,” Dr. Ford notes. “You can also get swelling in the legs and midsection.”
A 5-day course of prednisone can cause short-term side effects, including changes in mood, appetite, sleep, and energy. The severity of the side effects depends on the dose of prednisone. Low doses are less likely to cause adverse effects than high doses of prednisone.
Prednisone has a tendency to raise the level of glucose, or sugar, in the blood, which can cause increased body fat or diabetes in some people. It is important to avoid "simple" carbohydrates and concentrated sweets, such as cakes, pies, cookies, jams, honey, chips, breads, candy and other highly processed foods.
Prednisone generally works very quickly — usually within one to four days — if the prescribed dose is adequate to reduce your particular level of inflammation. Some people notice the effects of prednisone hours after taking the first dose.
A gradual reduction in prednisone dosage gives your adrenal glands time to resume their usual function. The amount of time it takes to taper off prednisone depends on the disease being treated, the dose and duration of use, and other medical considerations. A full recovery can take a week to several months.
Risks of Prednisone
More serious side effects, such as an increased risk of infections, psychological effects, weakening of bones, and bone fractures are associated with longer-term use.
This depends on your health problem or condition. You may only need a short course of prednisolone for up to 1 week. You may need to take it for longer, even for many years or the rest of your life.
There is no set limit on how long you can safely take prednisone. It depends on the dose of prednisone and the condition being treated. It may be prescribed short term or long term. The dosage will be adjusted or stopped based on your response or lack of response to the medication.
Prednisone is the steroid most commonly prescribed for lupus. It is usually given as tablets that come in 1, 5, 10, or 20 milligram (mg) doses.
It's best to avoid drinking alcohol while taking prednisone or other corticosteroids (“steroids”). Alcohol can make some steroid side effects worse. It can also sometimes worsen the underlying condition being treated. On their own, steroids, like prednisone, and alcohol can suppress your immune system.
Prednisone, like other corticosteroids, quickly lowers inflammation, which cuts down on pain, redness, and swelling. It also dials down your immune system.

You could expect a dose of prednisone to stay in your system for 16.5 to 22 hours. The elimination half life of prednisone is around 3 to 4 hours. This is the time it takes for your body to reduce the plasma levels by half.
Yes. Prednisone is one of several medications known to cause weight gain. This is usually more likely to happen with long-term use or higher doses.
Fluid retention can cause weight gain but as steroids are reduced, fluids will usually reduce as well, along with some of the weight gain. Drinking plenty of water and exercising can help with fluid retention.
Things to avoid (or cut back on) while taking prednisone include: Caffeine: Caffeine can add to the unwanted stimulant effects of prednisone. Combining caffeine with steroids can keep you awake at night or make you feel jittery and anxious.
Short-term treatment (7–14 days) with oral prednisone is used for many acute inflammatory and allergic conditions.
Prednisone side effects are common and can include insomnia, abnormal hair growth, fatigue, thinning of the skin, constipation, and more.
High blood pressure. Problems with mood swings, memory, behavior, and other psychological effects, such as confusion or delirium. Upset stomach. Weight gain in the belly, face and back of the neck.
Long-term use of prednisone may lead to bone loss and osteoporosis. It can cause changes in the distribution of body fat which together with fluid retention and weight gain may give your face a moon-like appearance. Stretch marks, skin thinning, and excessive facial hair growth are also not uncommon.
