Prednisolone is a synthetic glucocorticoid drug. It has anti-inflammatory, anti-allergic, immunosuppressive, antioxidative and antipruritic effects. The immunosuppressive effect is associated with inhibition of cytokines release from lymphocytes and macrophages. Other effects are caused by the stabilization of cell membranes, decreased capillary permeability, and improved microcirculation.
Prednisolone has a catabolic effect, increases the level of glucose in the blood, and causes the redistribution of adipose tissue. The drug inhibits the synthesis and secretion of adrenocorticotrophic hormone and, secondly, adrenal corticosteroids.
With the external and local applications, the therapeutic activity of prednisone is achieved due to anti-inflammatory, anti-allergic and antioxidative effects.

Dosage and mode of application
The dose and duration of treatment are selected by the doctor individually, depending on the indications and severity of the disease.
Typically, the daily dose is taken once or taken as a double dose every other day, in the morning, in the interval from 6 to 8 hours in the morning.
A high daily dose can be divided into 2-4 doses, while a large dose should be taken in the morning.
Tablets should be taken during or immediately after a meal with a small amount of liquid.
In acute conditions and as replacement therapy, adults have prescribed an initial dose of 20-30 mg/day, the maintenance dose is 5-10 mg/day. In some diseases (nephrotic syndrome, some rheumatic diseases), higher doses are prescribed. Treatment is stopped slowly, gradually reducing the dose. If there is a history of psychosis, high doses are prescribed under strict physician supervision.
Doses for children: the initial dose is 1-2 mg/kg/day in 4-6 doses, the maintenance dose is 0.3-0.6 mg/kg/day.
For short-term use for health reasons, contraindications include:
- hypersensitivity to prednisone or drug’s components;
- lactase deficiency, lactose intolerance, sucrose/isomaltase deficiency, fructose intolerance, glucose-galactose malabsorption;
- children’s age up to 3 years.
The drug should be used with caution in the following diseases and conditions:

- active and latent tuberculosis.
- the use in severe infectious diseases is permissible only on the background of specific therapy;

Pregnancy and lactation
During pregnancy, the use of prednisone is possible if the intended benefit to the mother outweighs the potential risk to the fetus.
In the first trimester of pregnancy, prednisone is used only for health reasons.
With prolonged therapy during pregnancy, the possibility of impaired fetal growth is not ruled out. If used in the third trimester of pregnancy, there is a risk of atrophy of the adrenal cortex in the fetus, which may require replacement therapy in the newborn.
Since corticosteroids penetrate into breast milk, if it is necessary to use the drug during breastfeeding, breastfeeding is recommended to be arrested.
Tell your doctor if you are taking, have recently taken, or intend to take any other drugs. This applies to any herbal preparations or preparations that you bought without a prescription.
