Prednisone



What is prednisone?
Prednisone is in a class of drugs called steroids. Prednisone prevents the release of substances in the body that cause inflammation.

Prednisone is used to treat many different conditions such as allergic disorders, skin conditions, ulcerative colitis, arthritis, lupus, psoriasis, or breathing disorders.

Prednisone may also be used for other purposes not listed in this medication guide.

What is the most important information I should know about Deltasone (prednisone)?
You should not use this medication if you are allergic to prednisone, or if you have a fungal infection anywhere in your body.

Before taking prednisone, tell your doctor about all of your medical conditions, and about all other medicines you are using. There are many other diseases that can be affected by steroid use, and many other medicines that can interact with steroids.

Your steroid medication needs may change if you have any unusual stress such as a serious illness, fever or infection, or if you have surgery or a medical emergency. Tell your doctor about any such situation that affects you during treatment.

Steroid medication can weaken your immune system, making it easier for you to get an infection or worsening an infection you already have or have recently had. Tell your doctor about any illness or infection you have had within the past several weeks.

Avoid being near people who are sick or have infections. Call your doctor for preventive treatment if you are exposed to chicken pox or measles. These conditions can be serious or even fatal in people who are using steroid medication.

Do not receive a "live" vaccine while you are taking prednisone. Vaccines may not work as well while you are taking a steroid.
Do not stop using prednisone suddenly, or you could have unpleasant withdrawal symptoms. Talk to your doctor about how to avoid withdrawal symptoms when stopping the medication. Carry an ID card or wear a medical alert bracelet stating that you are taking a steroid, in case of emergency.

What should I discuss with my healthcare provider before taking Deltasone (prednisone)?
You should not use this medication if you are allergic to prednisone, or if you have a fungal infection anywhere in your body.

Steroid medication can weaken your immune system, making it easier for you to get an infection. Steroids can also worsen an infection you already have, or reactivate an infection you recently had. Before taking this medication, tell your doctor about any illness or infection you have had within the past several weeks.

If you have any of these conditions, you may need a dose adjustment or special tests to safely take prednisone.

Prednisone


BRAND NAME: Deltasone, Orasone, Prednicen-M, Liquid Pred
DRUG CLASS AND MECHANISM: Prednisone is an oral, synthetic (man-made) corticosteroid used for suppressing the immune system and inflammation. It has effects similar to other corticosteroids such as triamcinolone (Kenacort), methylprednisolone (Medrol), prednisolone (Prelone) and dexamethasone (Decadron). These synthetic corticosteroids mimic the action of cortisol (hydrocortisone), the naturally-occurring corticosteroid produced in the body by the adrenal glands. Corticosteroids have many effects on the body, but they most often are used for their potent anti-inflammatory effects, particularly in those conditions in which the immune system plays an important role. Such conditions include arthritis, colitis, asthma, bronchitis, certain skin rashes, and allergic or inflammatory conditions of the nose and eyes. Prednisone is inactive in the body and, in order to be effective, first must be converted to prednisolone by enzymes in the liver. Therefore, prednisone may not work as effectively in people with liver disease whose ability to convert prednisone to prednisolone is impaired

PRESCRIPTION: yes

GENERIC AVAILABLE: yes

PREPARATIONS: Tablets of 2.5, 5, 10, 20, and 50 mg. Oral solution or syrup of 5mg/5ml

STORAGE: Store at room temperature 20-25°C (68-77°F), and keep away from moisture.

PRESCRIBED FOR: Prednisone is used in the management of inflammatory conditions or diseases in which the immune system plays an important role. Since prednisone is used in so many conditions, only the most common or established uses are mentioned here. Prednisone most often is used for treating several types of arthritis, ulcerative colitis, Crohn's disease, systemic lupus, allergic reactions, asthma and severe psoriasis. It also is used for treating leukemias, lymphomas, idiopathic thrombocytopenic purpura and autoimmune hemolytic anemia. Corticosteroids, including prednisone, are commonly used to suppress the immune system and prevent the body from rejecting transplanted organs. Prednisone is used as replacement therapy in patients whose adrenal glands are unable to produce sufficient amounts of cortisol.

DOSING: The initial dose of prednisone varies depending on the condition being treated and the age of the patient. The starting dose may be from 5 to 60 mg per day and often is adjusted based on the response of the condition being treated. Corticosteroids typically do not produce immediate effects and must be used for several days before maximal effects are seen. It may take much longer before conditions respond to treatment. Prolonged therapy with prednisone causes the adrenal glands to atrophy and stop producing cortisol. When prednisone is discontinued after a period of prolonged therapy, the dose of prednisone must be tapered (lowered gradually) to allow the adrenal glands time to recover. (See side effects.) It is recommended that prednisone be taken with food.

DRUG INTERACTIONS: Prednisone may interact with estrogens and phenytoin (Dilantin). Estrogens may reduce the action of enzymes in the liver that break down (eliminate) the active form of prednisone, prednisolone. As a result, the levels of prednisolone in the body may increase and lead to more frequent side effects. Phenytoin increases the activity of enzymes in the liver that break down (eliminate) prednisone and thereby may reduce the effectiveness of prednisone. Thus, if phenytoin is being taken, an increased dose of prednisone may be required.
