Steroids affect multiple organs, but the most significant and potentially life-threatening impacts occur in the cardiovascular system and the liver. Long-term, high-dose use of anabolic steroids causes damage across numerous bodily systems.
The enzymatic system for cortisol metabolism is primarily in the liver. Corticosteroid metabolites are excreted in the urine—the primary urinary metabolite of cortisol Tetrahydrocortisol.
Patients on moderate to high doses of prednisone often notice that they bruise easily, even with only slight trauma. Pictured below is a patient with giant cell arteritis who suffered a skin laceration after she struck her leg against a chair.
Prednisone may cause gastrointestinal symptoms like: Nausea. Vomiting. Diarrhea.
Sometimes a person will think that fluid retention is akin to weight gain. 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.
Some medicines that corticosteroids could interact with include:
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.
Common side effects
Prednisone is usually detectable in blood for up to 22 hours, in urine for 24 to 36 hours, and in saliva for 12 to 24 hours. In hair follicles, its metabolites remain for up to 90 days. The drug is metabolized in the liver into prednisolone and excreted by the kidneys.
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).
Stay hydrated: Drinking lots of water and fluids helps support your kidneys as they flush out prednisone. Exercise: Physical activity helps support your metabolism and blood circulation. This helps your body process and eliminate drugs efficiently.
People with low levels of vitamin K may notice easy bruising. If you, your mom, and your sister all turn black and blue from the tiniest bump, it may be a family thing. Some people just have more fragile blood vessels, and that makes them more likely to bruise, especially on their upper arms, thighs, or butt.
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.
Some common symptoms of adrenal disorders include:
Studies show that anabolic steroids have detrimental and often irreversible effects on the brain and affect this organ primarily through two mechanisms: 1) Neural hyperstimulation by increasing the activation of specific neurotransmitters, such as norepinephrine, dopamine, and serotonin; 2) Significant reduction in ...
The ACTH stimulation test is the test used most often to diagnose adrenal insufficiency. In this test, a health care professional will give you an intravenous (IV) injection of man-made ACTH, which is just like the ACTH your body makes.
You could go into steroid withdrawal, which can have severe symptoms. It's safer to taper off prednisone. Your doctor will gradually lower your dose. Tapering helps prevent withdrawal and stop your inflammation from coming back.
If you're taking prednisone to treat an acute condition or illness, you'll likely only need to take the medication for a few days or weeks. This is considered to be a short-term course. For chronic conditions, long-term use (30 days or longer) may be more appropriate.
Prednisone withdrawal: Why do I need to slowly taper down the dosage? If you abruptly stop taking prednisone or taper off too quickly, you may experience withdrawal symptoms, including: Severe fatigue. Weakness.
If you take oral corticosteroids for a long time, your adrenal glands may produce less of their natural steroid hormones. To give your adrenal glands time to recover this function, your provider may reduce your dose gradually.
What may interact with this medication?
Prednisone looks like a stress hormone (cortisol) to the brain. Because of this, prednisone can act directly on the brain to stimulate appetite. Prednisone can also sometimes cause nausea and indigestion. These symptoms often resolve with eating, prompting people to eat more than usual.
A finger tip is from the very end of the finger to the first crease in the finger. One FTU is enough to treat an area of skin twice the size of the flat of an adult's hand with the fingers together. Two FTUs are about the same as 1 g of topical steroid.
The dose should be individualised according to the severity of the disease and the patient's response rather than by age or body weight. The usual adult prescribing limit is up to 250mg daily. Short Term Therapy: 20mg to 40mg daily with dosage reductions of 2.5mg or 5mg every 2 to 4 days depending on response.
