What is Prednisone?

Prednisone is a prescription medication from the drug class Corticosteroids (steroids). The drugs in this class function by mimicking the role of cortisol (a naturally produced hormone by the adrenal glands that helps the body cope with stress). The medication is effective at suppressing the body’s dysfunctional immune system and minimizing inflammation. Prednisone is a prodrug that is converted into an active prednisolone by the liver post consumption. The medication is FDA-approved and available in various strengths ranging from 2.5mg to 40mg as oral tablets and solutions. Prednisone is marketed under the brand names Rayos, Sterapred, and Deltasone; the drug is also available as Generic Prednisone Tablets.

Uses of Prednisone

Prednisone is a corticosteroid (steroid) that is used for multiple purposes involving inflammation, a few of which are mentioned below:

• Autoimmune diseases like Lupus, Rheumatoid Arthritis

• Breathing issues like Asthma and COPD

• Skin diseases like eczema, psoriasis, and multiple sclerosis

• Allergic Reactions

• Digestive issues like Crohn’s and ulcerative colitis

• Aids in organ transplant

In addition to the above-mentioned conditions, this drug may also be prescribed for other purposes. However, before you buy Prednisone 20mg online to manage any condition, it is important to consult a healthcare specialist to determine whether the medication would be the right treatment option for you.

How does Prednisone help tackle various conditions?

Patients with the health conditions listed below can benefit from Prednisone as discussed below:

Autoimmune ailment is a condition in which the body’s own immune system accidentally attacks the body’s tissue. Prednisone helps address conditions such as lupus and rheumatoid arthritis by suppressing the abnormal function of the immune system.

Asthma and COPD

Inflammation of the airways leads to difficulty breathing. Prednisone helps reduce inflammation and allows the airways to relax, enabling the smooth passage of air and making breathing easier.

Skin Conditions

Prednisone helps manage skin conditions such as eczema and severe dermatitis by suppressing the immune system and preventing further spread of inflammation. Thus, the medication reduces redness, rashes, itching, and swelling of the skin.

Allergies

When people with certain allergies do not get relief from antihistamines, doctors may prescribe Prednisone as an alternative treatment. Prednisone is a synthetic corticosteroid (steroid) that functions similarly to the natural cortisol in the body. Cortisol keeps a check on overreactive immune responses and inhibits inflammatory chemicals such as cytokines and prostaglandins, thereby helping address severe allergies.

Digestive Issues

Swelling in the digestive tract leads to inflammation and irritation. Steroids help provide quick relief from gut inflammation, thereby alleviating digestive issues such as Crohn’s Disease, Irritable Bowel Disease, and Ulcerative Colitis.

Helps Organ Transplant

Since Prednisone is known to suppress the immune system, it is an important tool for ensuring the success of a new organ transplant. The weakened immune system fails to recognize the new organ as a foreign body and prevents it from attacking the new organ.
