The experience of being on steroids varies widely depending on whether they are anabolic steroids (used for muscle building) or corticosteroids (used for medical conditions like inflammation), the dosage, and the individual. Effects can range from increased confidence and energy to severe mood swings, aggression, and physical discomfort.
Some people who take steroids say the drugs make them feel powerful and energetic. However, steroids are also known to increase irritability, anxiety and aggression and cause mood swings, manic symptoms and paranoia, particularly when taken in high doses.
Steroids affect areas of the brain that manage the regulation of neurotransmitters like serotonin and dopamine, which are also known as the feel-good hormones. Some people actually experience euphoria when taking steroids like prednisone.
Prednisone may cause gastrointestinal symptoms like: Nausea. Vomiting. Diarrhea.
Hydrocortisone injections are a steroid (or corticosteroid) medicine. The injection releases the hydrocortisone slowly into the part of your body that is painful or swollen. Like other steroids, it works by calming down your immune system. This reduces inflammation and helps to relieve the pain and swelling.
Side effects depend on the dose of medication you receive and may include: A buildup of fluid, causing swelling in your lower legs. High blood pressure. Problems with mood swings, memory, behavior, and other psychological effects, such as confusion or delirium.
Prednisone usually achieves its effect within 1–2 hours. The delayed release tablets take about 6 hours after taking the dose. Prednisone stops working soon after stopping the medication.
Higher doses and longer courses of steroids are much more likely to cause weight gain. Low doses and shorter courses are unlikely to cause any change in weight.
RESULTS: Steroids reduced the number of bowel movements by more than five times within one week and all patients reported improved subjective well-being at wk 1 and 4.
Last updated on Dec 5, 2025. Prednisone does not usually cause sleepiness but it might make you feel dizzy, irritable with mood swings, or cause you to have trouble sleeping (insomnia). If your dose is stopped too quickly or if you take prednisone for a long period of time you may feel severely fatigued (tired).
Based on these findings we have something called as Rule of 2. If a patient consumed 20mg/day or more Cortisone or its equivalent, for a duration of 2 weeks or more, within 2 years then the dosage of the steroid medication should be doubled preoperatively.
How long is the immune system compromised after steroid injection? The immune system may be compromised shortly after a steroid injection, typically lasting a few days to a week. However, this can vary depending on factors such as the type and dosage of the steroid medication and individual health conditions.
The steroid acts on the irritated nerve(s) that are causing your pain and reduces swelling and pressure on the nerves. Lumbar epidural steroid injections most often lead to temporary pain relief that lasts for three months or more, but some people may experience less or no pain relief from the injection.
Serious side effects
a high temperature (or you feel hot, cold or shivery), a very sore throat, ear or sinus pain, a cough, more saliva or a change in colour of saliva (yellowish and possibly with streaks of blood), pain when you pee, mouth sores or a wound that will not heal – these can be signs of an infection.
It is a clinical impression that some patients given oral corticosteroids develop a sense of wellbeing that is 'inappropriate' to improvements in physical health. This has been termed steroid 'euphoria', but unlike steroid-induced psychosis it has not been documented.
Side effects of oral corticosteroids: short-term use
Short-term use of OCS (about 3-5 days) can cause the following side effects: Weight gain, particularly in abdomen, face or neck. Eye problems. Muscle weakness.
Steroids affect your metabolism and how your body deposits fat. This can increase your appetite, leading to weight gain, and in particular lead to extra deposits of fat in your abdomen. Self-care tips: Watch your calories and exercise regularly to try to prevent excessive weight gain.
Yes, you can drink alcohol while taking prednisolone. Is there any food or drink I need to avoid? Do not eat real liquorice while taking prednisolone. It's thought that real liquorice increases the amount of prednisolone in the body and also increases the risk of low potassium.
The major classes of steroid hormones, as noted above (with their prominent members and functions), are the progestogens, corticosteroids (corticoids), androgens, and estrogens.
The starting dose of prednisone may be between 5 mg to 60 mg per day. A dose above 40 mg per day may be considered a high dose. However, everybody responds differently to prednisone, so what might be a high dose depends on the person and the condition.
Moon Face Is More Common in Long-Term, High-Dose Steroid Use. You might wonder how long after starting a steroid like prednisone moon face might occur. Moon face may appear within the first two months of steroid therapy, though the risk depends on dosage and length of treatment.
Drinking plenty of water and exercising can help with fluid retention. Weight gain and increase in appetite – Sometimes if you are also taking an immunosuppressive, the appetite might be decreased.
However, cases of corticosteroid resistance or rebound inflammatory response during corticosteroid tapering or after discontinuation have been reported [3,5–7].
Opioids. Your doctor may also prescribe a medicine called an opioid for lower back pain. Weak opioids (such as codeine) may be given for moderate pain. For severe and persistent pain, you may need stronger opioids, such as morphine.
Prednisone can make you feel different than normal. But there are steps you can take to decrease the risk of unwanted side effects. Things to avoid (or cut back on) while taking prednisone include: Caffeine: Combining caffeine with prednisone can keep you awake at night or make you feel jittery and anxious.
