What prednisone is and why doctors prescribe it
Prednisone is a prescription drug. It is a type of corticosteroid. It works by easing swelling in the body. Doctors use it to help in many conditions. These include asthma attacks, allergic reactions, and skin rashes. It is also used for arthritis and some blood or cancer conditions. By lowering the immune response, it can calm the body. You get it as a pill or liquid. Your doctor will tell you how much to take and for how long. It often acts fast to ease symptoms. You may need tests to see how well it works. Always take it as your doctor says. Do not stop or change the dose on your own. Ask your doctor if you have questions about other medicines you take. For more details, see the FDA prescribing information and the MedlinePlus guide.
It may come in low or high dose forms. Your doctor will pick the dose that fits your illness. Some people take it only for a few days. Others may need weeks or months of treatment. If you take it every day, your body may stop making its own natural steroid. This is why you must not stop all at once. You may have a plan to lower the dose slowly. Your health team will check blood tests, blood pressure, and eye health. They will also watch for bone loss and high blood sugar. It can help many people improve their health. It is key to follow the plan set by your doctor.
Quick answer: common prednisone side effects
Many people have side effects in the first days or weeks. The most common reactions are more hunger and weight gain. You may feel bloated or have fluid in your hands and feet. You might notice acne or more sweat on your skin. Some people have a higher heart rate or blood pressure. Other early signs are trouble sleeping and feeling restless at night. You could feel sad, anxious, or irritable. A headache or muscle ache may also show up. Less often, nausea or indigestion occurs. If you have high blood sugar, you may see more thirst or the need to urinate more. Talk to your doctor if any new sign bothers you or lasts more than a few days.
These effects can vary by dose. Low short courses often cause mild issues. Higher doses or longer use make side effects more likely. To learn more on these early changes, read the Mayo Clinic side effect list. If you notice fast weight changes, see our article on why you gain weight.
Many of these effects go away in a few days after you stop the drug. But some may stay longer.
Short-term side effects
In the first few days or weeks, you may see short-term effects. Some of these are mild. Others may need attention. Common issues include a rise in hunger and weight gain. Some people have body-fluid buildup called edema. Your stomach may feel upset or you may get indigestion. Nausea and belly pain can happen. Take your dose with food to help your stomach.
Other changes may affect your mind and mood. You could feel restless or have trouble sleeping at night. Insomnia may start quickly. You may feel more anxious or sad. Some people notice irritability or mood swings. A few may have severe changes like confusion or more serious mental signs.
Your skin may also change. You might get acne or sweat more. You may see red or puffy skin. A headache or rapid heartbeat can show up too. Short-term prednisone side effects are more common at higher doses. If you have diabetes, you may have a rise in your home glucose checks. You may be thirsty or need to pee more. If you have high blood pressure, check your readings more often. A mild rise may not be a concern. But call your doctor if home checks show a large jump or if you feel ill.
Most mild effects go away after you finish treatment. If they do not, tell your health pro. You may need medicine to ease some signs. The NHS notes that you can lower upset by taking it in the morning.
Long-term prednisone side effects and risks
When prednisone is used for weeks or months, the risk of serious harm rises. Long-term use can weaken bones and cause osteoporosis. You may get fractures from small injuries. Muscle weakness can make daily tasks hard. The body may stop making its own steroid hormone. This is called adrenal suppression. If you stop the drug too fast, you could get weak, dizzy, or ill.
Skin and soft tissue can change. Long use can thin the skin. You may bruise easily and have slow wound healing. You may see stretch marks or red lines on the skin. Eyes can be harmed by long-term use. You may get cataracts or glaucoma. You may notice vision changes or eye pain. Talk to an eye doctor if you see any shift in your sight.
Long treatment also raises the chance of infections. Prednisone lowers your immune defense. You may not have a fever even with a bad infection. Call your doctor for any fever, cough, or pain when you pee. Your clinician may check your lungs and urine. In rare cases, you may get a serious infection that needs hospital care.
The StatPearls review shows many other long-term risks. These can include high blood sugar, skin changes, and eye issues. Your care team may give bone-strength drugs and check your labs. They may also guide you in diet and exercise. Do not change the dose or stop without help from your doctor.
You may notice a change in how fat is stored in your body. Long-term use can cause fat to build up in your face, back, and belly. This can make your face look rounder. You may see more fat around your neck and upper back. Your belly may grow bigger even if you do not eat more. This change in fat is not weight you can lose with diet alone. Talk to your doctor about ways to manage this change.
Regular health checks are key. Your doctor may do bone scans to watch for bone loss. Blood tests can check your sugar levels. Your blood pressure should be checked often. Eye exams can spot cataracts early. Your care team will look at your muscle strength and skin health. They can help you make a plan to protect your body.
Prednisone Side Effects by Body System
Weight and Appetite
Many people feel very hungry on prednisone. This can lead to quick weight gain. You may also hold onto extra fluid. This can cause a puffy face or swollen legs. To help, eat protein-rich foods. Limit salt and sugary snacks. Talk to a diet expert if you need a plan.
Sleep and Mood
Prednisone can make it hard to sleep. You may feel restless or wake up often. Taking your dose in the morning may help. Some people feel jittery, anxious, or sad. Others may feel unusually happy or full of energy. If mood changes worry you, call your health pro.
Stomach and Digestive
This drug can upset your stomach. You may get indigestion, acid, or pain in your belly. To reduce this, take pills with food or milk. Avoid alcohol and NSAIDs unless your doctor says it is OK. Tell your doctor if you see black or bloody stools, or vomit red or dark matter.
Blood Sugar and Pressure
Prednisone can raise blood glucose. If you have diabetes, check your sugar more often. You may need to adjust your diabetes medicine. This drug can also raise blood pressure. Check your readings at home. If you see a big rise, call your clinician.
Bones and Muscles
Long use can weaken bones and muscles. You may break bones more easily. You may feel weak or tire fast. Your doctor may order bone scans and suggest calcium or vitamin D. Weight bearing exercises can help build strength.
Eyes
Over time, you can get cataracts or glaucoma. You may notice cloudy sight or eye pain. Regular eye exams can find these early. Your doctor may refer you to a specialist.
Infection Risk
Prednisone lowers your defense against germs. You can catch illnesses more easily. You may not get a fever, so watch for any new cough, sore throat, or pain. Your skin may turn red or sore. If you have signs of infection, call your doctor right away.
Who has a higher risk of complications
Some people have a greater chance of harm from this medicine. People with diabetes, high blood pressure, or high blood sugar run a higher risk. Those with weak bones or a history of fractures may see more bone loss. People with eye problems like glaucoma or cataracts may get worse issues. Those with a history of ulcers or stomach bleeding face a higher risk. People with mental health conditions such as anxiety or depression may have more mood changes. In general, people with serious health conditions may have stronger prednisone side effects.
A high dose or a long treatment plan also raises risk. Taking the drug every day for more than a few weeks makes side effects more likely. Using steroids along with blood thinners or certain pain medicines can harm your stomach. If you drink alcohol often, the risk of ulcers and bleeding goes up. Tell your doctor about all your health issues and medicines before you start.
Age matters too. Older adults may have more bone loss and weaker muscles. Children can grow slower on long courses. Pregnant or breastfeeding people need special advice. Always talk to your doctor if you are in one of these groups. Your doctor may change your plan or add medicine to protect you.
Your care team may check labs, bone health, and eye tests more often if you have risk factors. They can suggest diet, exercise, and supplements to lower harm. Close follow up helps keep checks normal and side effects mild.
How to reduce risk while taking prednisone
You can limit prednisone side effects by taking the drug with food. This may help your stomach. If your dose is once a day, take it in the morning. This can lower sleep issues. Never skip, double, or stop a dose on your own. You need a taper plan when you finish.
Talk to your doctor and pharmacist about all medicines and supplements you use. Avoid NSAIDs like ibuprofen or naproxen unless your doctor says it is OK. Limit alcohol. Ask if any herbal product can harm your care. If you have diabetes, work with your diabetes team. You may need to check your sugar more often and change your insulin.
Eat a balanced diet with enough protein, calcium, and vitamin D. You can add dairy, fish, nuts, and leafy greens. Limit extra salt to reduce fluid build up. Do weight bearing or resistance exercises if your doctor agrees. This can help your bones and muscles stay strong.
Your care team may suggest medicine to protect your bones if you will use prednisone long term. They may order regular blood tests, bone scans, eye exams, and heart checks. Keep all your follow up visits. Report new symptoms as soon as you see them.
Why prednisone should not be stopped suddenly
Stopping prednisone suddenly can cause rebound prednisone side effects. Your body may have a hard time making its own natural steroid. This can lead to adrenal insufficiency. You may feel very weak, tired, and dizzy. You may have nausea, vomiting, and body pain. You may feel lightheaded when you stand up. In severe cases, you may pass out or need hospital care.
Doctors make a taper plan based on your dose and how long you have taken the drug. This plan helps your body adjust. Never stop or cut your dose in half on your own. Always call your doctor before you make changes. If you miss a dose, follow the directions given by your care team.
After you finish the taper, you may still feel tired or weak. This may last for days or weeks. Call your doctor if you have signs of low blood pressure, confusion, or fainting. You may need a stress dose of steroid if you get sick or have surgery.
Keep a list of your doses and dates. Share this with every doctor you see. This list can help prevent a sudden stop and keep you safe.
Stopping too fast can also cause the original condition to flare up. For example, asthma attacks or joint pain may return. This can be dangerous if you thought your problem was done. A slow cut helps your body and your illness stay in balance.
When to call a doctor or seek emergency care
Contact your doctor right away if you have signs of infection. This includes fever, chills, cough, or painful urination. Also call if you have a new or worse mood change, such as severe anxiety or confusion. If you see rapid weight gain, swelling of your legs or face, or a big rise in blood pressure, get help.
Watch for urgent signs. Seek emergency care if you have trouble breathing, chest pain, or swelling of your lips, tongue, or throat. Go to the hospital or call 911 if you vomit blood or have black, tarry stools. If you have sudden vision changes or severe eye pain, get help fast. Also seek help for severe muscle weakness, fainting, or severe stomach pain.
If you see severe prednisone side effects like black stools or vomiting blood, do not wait. Get emergency care. If you feel suicidal or have severe confusion, seek help right away. If you have signs of low blood pressure such as dizziness or fainting, call for help. Do not try to drive yourself.
For new or mild worries, call your clinician instead of the ER. Ask for the office number and after-hours line. Keep your health team contact list handy. Early calls can prevent more harm and keep you safe.
Talk to your doctor if you have persistent high blood sugar. Signs include extreme thirst, blurry vision, and frequent urination. Ask if you need a change to your diabetes plan. If you notice slow wound healing or easy bruising, let your care team know. These can be signs of deeper effects on your skin and blood vessels.
