Prednisone

Prednisone is a prescription drug that is used to help decrease inflammation and suppress an overactive immune system. The medication comes in either liquid or tablet form and is taken just once a day or several times a day, depending on the condition being treated. Some side effects that have been reported with prednisone include high blood pressure, headaches, and stomach irritation.

What Is Prednisone?

Prednisone is a prescription medication used to treat a wide variety of conditions. It is part of a group of medications known as glucocorticoids, corticosteroids, or simply "steroids" for short.

Who Makes Prednisone?

It is made by numerous manufacturers of generic medications.
 

How Does It Work?

Prednisone is part of a group of medications called glucocorticoids. These medicines are a type of corticosteroid, or "steroid" for short. Prednisone is similar to glucocorticoids that occur naturally in the body.
 
Although glucocorticoids have numerous affects in the body, they are used mostly for their anti-inflammatory or immune-suppressing properties. This drug works for most conditions by decreasing inflammation or suppressing an overactive immune system.
 
When prednisone is taken for more than a few weeks, the body becomes accustomed to it and begins to make less of its natural steroids. If it is stopped too quickly, the body does not have time to adjust, and dangerous side effects can occur (see Prednisone Withdrawal).
 

When and How to Take Prednisone

Some general considerations for when and how to take prednisone include:
 
  • The medication comes in tablet form and is taken by mouth. It can be taken just once a day or several times a day, depending on the condition being treated. If you are taking it just once a day, it is usually best to take it in the morning. Some people take it every other day.
     
  • Taking it too late in the evening may cause difficulty sleeping for some people. If you notice this problem, ask your healthcare provider about taking your dosage earlier in the day.
     
  • It is also available in liquid forms for people who have difficulty swallowing tablets.
     
  • Your dosage should always be taken with food, as it can be irritating to the stomach.
     
  • It should be taken at the same time(s) each day to maintain even levels of medicine in your blood.
     
  • For the medication to work properly, it must be taken as prescribed. Do not take prednisone longer than prescribed, and do not stop taking it suddenly (see Prednisone Withdrawal).
     

Dosing Information

The dosage that your healthcare provider recommends will vary depending on a number of factors, including:
 
  • The medical condition being treated
  • The severity of your condition
  • Your age and weight
  • Other medications you may be taking
  • Other medical conditions you may have.
     
As always, do not adjust your dose unless your healthcare provider specifically instructs you to do so.

If side effects do occur, in most cases they are minor and either require no treatment or can easily be treated by you or your healthcare provider. Serious side effects are less common.
