1. What is Meprelon and what is it used for

The active substance of Meprelon is a glucocorticosteroid (adrenal cortex hormone) that affects metabolism (i.e., metabolism), water and electrolyte balance, and tissue function. Meprelon is used in diseases that require the administration of glucocorticosteroids. Depending on the symptoms and severity, these include inflammatory and systemic rheumatic diseases, autoimmune diseases, allergic conditions, anaphylactic shock, severe asthma, and transplant rejection.

• Rheumatic diseases: progressive rheumatoid arthritis in severe, progressive form, e.g., with rapid joint destruction, and extra-articular forms.
• Juvenile rheumatoid arthritis with a severe course, involving internal organs (Still's syndrome) or eyes, when local treatment is ineffective (uveitis and adjacent structures).

Respiratory diseases:

• Bronchial asthma (concomitant administration of bronchodilators is recommended).
• Exacerbation of chronic obstructive pulmonary disease (recommended treatment period: up to 10 days).
• Specific lung diseases, such as acute alveolitis, pulmonary fibrosis; maintenance treatment of chronic sarcoidosis in stage II and III (with dyspnea, cough, and worsening lung function parameters).
• Severe forms of hay fever and allergic rhinitis after failure of treatment with a glucocorticosteroid nasal spray.

Skin diseases:
Diseases of the skin and mucous membranes that cannot be sufficiently treated with topical corticosteroids due to their severity and/or extent or involvement of internal organs. These include:

• Allergic reactions and pseudo-allergic reactions, allergic reactions associated with infections, e.g., urticaria, anaphylactoid reactions.
• Severe skin reactions, sometimes causing skin destruction, drug rash, erythema multiforme, toxic epidermal necrolysis (Lyell's syndrome), generalized acute pustular psoriasis, nodular erythema, severe febrile neutrophilic dermatosis (Sweet's syndrome), allergic contact dermatitis.
• Immune system diseases (autoimmune diseases), e.g., dermatomyositis, discoid and subacute lupus erythematosus.

Blood diseases:
Autoimmune blood diseases: anemia due to red blood cell destruction (acquired autoimmune hemolytic anemia).
Gastrointestinal diseases:

• Ulcerative colitis.
• Crohn's disease.

Replacement therapy:
Reduced or absent adrenal cortex function (adrenal insufficiency of any cause, e.g., Addison's disease, adrenogenital syndrome, postoperative adrenal removal, hypopituitarism) after completion of growth (hydrocortisone and cortisone are drugs of choice).

2. Important information before taking Meprelon

When not to take Meprelon

• If the patient is allergic to methylprednisolone or any of the other ingredients of this medicine (listed in section 6).
• If the patient has systemic fungal infections. Except for allergic reactions, there are no contraindications to short-term use of Meprelon in life-threatening conditions or replacement therapy.

Warnings and precautions

Before starting to take Meprelon, discuss it with your doctor or pharmacist,

• if the patient has hyperthyroidism. If it is necessary to use Meprelon in doses higher than replacement doses (doses used to supplement the lack of corticosteroids produced by the human body), Meprelon should only be used when the doctor considers it necessary. In some cases, specific-acting drugs against disease-causing factors must be used simultaneously. This applies to the following cases:
• acute viral infections (chickenpox, shingles, herpes virus infections, herpes simplex keratitis);
• acute and chronic bacterial infections;
• fungal infections with internal organ involvement;
• certain parasitic diseases (strongyloidiasis, worm infestations);
• lymph node disease after tuberculosis vaccination (in case of tuberculosis in the medical history, the medicine can only be used simultaneously with anti-tuberculosis drugs);
• hepatitis (chronic active hepatitis with a positive HBsAg test result);
• poliomyelitis;
• about 8 weeks before and up to 2 weeks after protective vaccinations using live vaccines.

Meprelon can be used in the course of the following diseases only when the doctor considers it necessary, and the disease will be treated according to the applicable rules:

• peptic ulcer disease;
• hypertension that is difficult to control;
• severe diabetes;
• osteoporosis;
• mental illnesses (also in the medical history);
• increased intraocular pressure (glaucoma with closed or open angle);
• corneal damage and ulcers.

Due to the risk of intestinal perforation and peritonitis, Meprelon can only be used with absolute indications and under proper control in the course of the following diseases:

• severe ulcerative colitis (ulcerative colitis) with a risk of perforation, with abscesses or abscessing;
• diverticulitis;
• after certain intestinal surgeries (intestinal anastomoses) immediately after surgery.

In patients taking high doses of glucocorticosteroids, symptoms of peritonitis after gastrointestinal perforation may be masked.
Taking Meprelon may cause gas accumulation in the intestinal wall, called intestinal pneumatosis cystoides (see section 4 "Possible side effects"). Intestinal pneumatosis cystoides can range from a mild condition that does not require treatment to more severe conditions that may require immediate treatment.
If symptoms such as nausea, vomiting, and abdominal pain occur, which persist or worsen, you should contact your doctor immediately. The doctor will decide on the need for further diagnosis and treatment.
During treatment for a specific type of muscle paralysis (myasthenia), there may be an initial worsening of symptoms. Therefore, Meprelon should initially be administered in a hospital. Especially in cases of severe facial and throat disorders with breathing difficulties, Meprelon should be introduced gradually.
Meprelon may mask infection symptoms, making it difficult to diagnose an existing or developing infection. Long-term use of even small doses of methylprednisolone leads to an increased risk of infection with microorganisms that usually rarely cause infections.
In principle, it is possible to vaccinate with vaccines containing killed microorganisms. However, it should be remembered that when taking higher doses of Meprelon, the effectiveness of the vaccination may be reduced.
In patients with diabetes, metabolism (metabolism) should be regularly monitored. It is necessary to consider possible increased demand for diabetes medications (insulin, oral medications, etc.).
Especially during long-term treatment with relatively high doses of Meprelon, attention should be paid to adequate potassium intake (e.g., vegetables, bananas) and sodium restriction. The doctor should monitor blood potassium levels.
In cases of severe hypertension or severe heart failure, the doctor should carefully monitor the patient, as there is a risk of deterioration.
Before starting to take Meprelon, discuss it with your doctor if:
Patient has scleroderma (an autoimmune disorder also known as systemic sclerosis), as doses of at least 12 mg per day may increase the risk of a serious complication called scleroderma renal crisis. Scleroderma renal crisis includes symptoms such as high blood pressure and decreased urine production. The attending physician may recommend regular blood pressure and urine output checks.
Inform your doctor if you experience symptoms of tumor lysis syndrome, such as muscle cramps, muscle weakness, confusion, vision loss or disturbances, shortness of breath, seizures, irregular heartbeat, or kidney failure (decreased urine output or darker urine color), as well as in cases where you have a blood cancer (see section 4 "Possible side effects").
After administering Meprelon, cases of pheochromocytoma crisis (high blood pressure, headache, excessive sweating, palpitations, pallor) have been reported, which can lead to death. Treatment of patients with suspected or diagnosed pheochromocytoma should only be started after careful assessment of the benefit-risk ratio.
If the patient experiences blurred vision or other vision disturbances, they should contact their doctor.
During long-term administration of Meprelon, regular medical check-ups (including ophthalmological check-ups) are necessary.
In cases where the body is under special stress, e.g., diseases with fever, injuries, or surgeries, the patient should consult their attending physician or inform the emergency doctor about the treatment being taken. Sometimes, a temporary increase in the daily dose of Meprelon may be necessary.
Depending on the duration of treatment and dose, there may be a negative impact on calcium metabolism. Therefore, osteoporosis prevention is recommended. This applies especially to people with existing risk factors, such as family history, advanced age, inadequate protein and calcium intake, smoking a large number of cigarettes, excessive alcohol consumption, postmenopausal period, or lack of physical activity. Prevention involves adequate calcium and vitamin D intake and physical activity. In cases of existing osteoporosis, the use of medications should also be considered.
After stopping or possibly interrupting long-term use of Meprelon, the following risks should be remembered:
exacerbation or recurrence of the underlying disease, acute adrenal insufficiency (especially in stressful situations, e.g., during infection, after injuries, with increased stress), "steroid withdrawal syndrome" (see section 4 "Possible side effects").
In patients treated with Meprelon, viral diseases may have a particularly severe course, especially in children with impaired immunity and people who have not previously had measles or chickenpox. In cases where these individuals come into contact with people suffering from measles or chickenpox while taking Meprelon, they should immediately consult a doctor, who may take preventive measures if necessary.
In cases of untreated hypothyroidism or liver cirrhosis, relatively small doses may be sufficient, or the dose may need to be reduced, which should be determined by a doctor.
Immediately consult a doctor if, during methylprednisolone treatment, weakness or muscle pain, cramps, and stiffness occur. These may be symptoms of a condition called thyrotoxic periodic paralysis, which can occur in patients with hyperthyroidism treated with methylprednisolone. Additional treatment may be necessary to alleviate this condition.

Children

Meprelon can be used in children only when absolutely necessary, due to the risk of growth retardation. Regular growth monitoring is necessary.
After systemic treatment with glucocorticosteroids in premature infants, a specific heart muscle disease (hypertrophic cardiomyopathy) has been observed. Therefore, in infants treated systemically with glucocorticosteroids, heart function should be monitored.

Elderly

In elderly patients, caution should be exercised due to the increased risk of side effects, such as diabetes, osteoporosis, and hypertension.

Effect of the medicine when used inappropriately as a doping agent

Taking Meprelon may result in positive test results for doping substances. Furthermore, using Meprelon as a doping substance can pose health risks.

Meprelon and other medicines

Tell your doctor about all medicines you are currently taking or have recently taken, including those available without a prescription.
Medicines that affect the action of Meprelon
Medicines that may enhance the action of Meprelon

• Certain medicines may enhance the action of Meprelon, and the doctor may want to carefully monitor the patient's condition when taking such medicines (including certain HIV medicines: ritonavir, cobicistat).
• Medicines that slow down the metabolism of corticosteroids in the liver, such as certain antifungal medicines (containing ketoconazole, itraconazole), may enhance the action of Meprelon.
• Certain female sex hormones, e.g., oral contraceptives: the action of Meprelon may be increased. Medicines that may weaken the action of Meprelon
• Medicines that accelerate its breakdown in the liver (barbiturates, phenytoin, primidone, carbamazepine - antiepileptic drugs, rifampicin - anti-tuberculosis drug): the action of Meprelon may be reduced.
• Medicines containing ephedrine, used to reduce swelling of mucous membranes, may accelerate the metabolism of glucocorticosteroids, which may reduce their effectiveness.

Other potential interactions

• Medicines used to treat heart diseases (e.g., diltiazem - a calcium channel blocker) may slow down the metabolism of methylprednisolone. Therefore, during the initial treatment period, it should be carried out under medical supervision. It may be necessary to adjust the dose of methylprednisolone.
• Medicines used to treat excessive stomach acid production (antacids): in patients with chronic liver disease, it may be necessary to increase the dose of Meprelon.

Influence of Meprelon on the action of other medicines
Enhancement of action

• Medicines used to treat heart failure (cardiac glycosides): due to the potential hypokalemia caused by Meprelon, their action may be increased.
• Diuretics and laxatives: their action is enhanced in the form of potassium excretion.
• Certain muscle relaxants (non-depolarizing muscle relaxants): muscle relaxation may last longer.

Weakening of action

• Antidiabetic medicines (oral, insulin): their action may be weakened, leading to increased blood sugar levels.
• Anticoagulant medicines (oral anticoagulants, coumarin derivatives): their blood-thinning action may be weakened.
• Medicines used to treat parasitic infections (praziquantel): the action of this medicine may be reduced.
• Growth hormones (somatotropin): their action is weakened, especially when Meprelon is used in higher doses.
• Protirelin (pituitary hormone): the increase in thyroid-stimulating hormone (TSH) levels is weakened. Other potential interactions
• Anti-inflammatory and anti-rheumatic medicines (salicylates, indomethacin, and other non-steroidal anti-inflammatory medicines): the risk of gastrointestinal ulcers or bleeding may increase.
• Certain ophthalmic medicines (atropine) and medicines with similar action (other anticholinergic medicines): intraocular pressure may increase further.
• Medicines used to treat malaria or rheumatic diseases (chloroquine, hydroxychloroquine, mefloquine): there is an increased risk of muscle diseases or heart muscle diseases.
• Cyclosporin (a medicine that reduces the body's immune response): the blood level of cyclosporin increases, leading to an increased risk of seizures.
• Certain medicines used to treat hypertension (angiotensin-converting enzyme inhibitors): there is an increased risk of blood disorders.

Influence on test results: the skin reaction in allergy tests may be reduced.

Pregnancy, breastfeeding, and fertility

If you are pregnant or breastfeeding, think you may be pregnant, or plan to have a child, consult your doctor or pharmacist before taking this medicine.
In animal studies, it has been shown that Meprelon has a fertility-impairing effect.
Until appropriate studies are conducted on the effect of Meprelon on human reproductive processes, this medicine should not be given to pregnant women unless a thorough assessment of the benefit-risk ratio for the mother and fetus has been made.
Certain corticosteroids easily cross the placental barrier. In one retrospective study, an increased incidence of low birth weight in newborns born to mothers taking corticosteroids was found. In humans, the risk of low birth weight is dose-dependent. This risk can be reduced by administering smaller doses of corticosteroids.
If there is a need to stop long-term use of Meprelon during pregnancy, it should be done gradually. In some situations (e.g., in replacement therapy for adrenal insufficiency), it may be necessary to continue treatment or even increase the dose. Children born to mothers who took Meprelon during pregnancy should be closely monitored and examined for adrenal insufficiency.
The effect of Meprelon on the course of labor is unknown.
In infants born to mothers who were treated with Meprelon for a long time during pregnancy, cataract development has been observed.
Meprelon passes into breast milk.
This medicine can be used by breastfeeding women only after a thorough assessment of the benefit-risk ratio for the mother and infant.

Driving and using machines

Due to the occurrence of certain side effects, such as impaired vision (due to cataracts or increased intraocular pressure), dizziness, or headaches, there may be a deterioration in the ability to concentrate and react. It is possible that the patient may not be able to react quickly enough to sudden and unexpected events. This may be associated with a risk, for example, when driving a vehicle or operating machinery. The patient may unnecessarily put themselves and others at risk. Note that alcohol can increase this risk.
The medicine contains less than 1 mmol (23 mg) of sodium per tablet, which means the medicine is considered "sodium-free".

3. How to take Meprelon

Always take this medicine exactly as your doctor has told you. If you are not sure, ask your doctor or pharmacist.
The doctor will determine the dose of the medicine individually for each patient, depending on the type of disease and the patient's individual response. The recommendations should be followed, as otherwise, the action of Meprelon will not be correct. In case of doubts, consult your doctor or pharmacist again.
Usually, relatively high initial doses are used (from 4 mg to 48 mg). These must be clearly higher in acute, severe forms of diseases than in chronic diseases.
Depending on the course of the disease, the dose can be reduced to a possible minimum maintenance dose (usually from 4 to 12 mg of methylprednisolone per day). Especially in the treatment of chronic diseases, long-term treatment with small maintenance doses is often necessary.
Method of administration
Meprelon is taken orally.
Usually, the tablets (the entire daily dose) are taken before or after breakfast (from 6:00 to

• 8:00), without chewing, with a sufficient amount of liquid, e.g., with a glass of water. If the clinical condition allows, the doctor may recommend taking the medicine every other day.

Taking a higher dose of Meprelon than recommended

Usually, Meprelon is well-tolerated without complications even after short-term use in high doses. There is no need for special measures. In case of intensified or atypical side effects, consult a doctor.

Missing a dose of Meprelon

A missed dose can be taken during the day. The next day, the dose is taken as usual. If several doses are missed, the disease may worsen. In such a case, consult a doctor, who will check and possibly correct the treatment.
Do not take a double dose to make up for a missed dose.

Stopping Meprelon treatment

Follow the doctor's instructions carefully. Do not stop taking Meprelon on your own. The doctor may prescribe a gradual reduction of the dose until the medicine is completely stopped.
In case of sudden withdrawal of Meprelon, remember the following risks (see also section 2 "Warnings and precautions"):
"steroid withdrawal syndrome" (see section 4 "Possible side effects"),
adrenal insufficiency (low cortisol levels),
exacerbation or recurrence of the underlying disease.
Prolonged use of Meprelon may lead to inhibition of the body's own glucocorticosteroid production. Severe stress on the body could be life-threatening (adrenal crisis).
If you feel that the action of Meprelon is too strong or too weak, consult your doctor or pharmacist.
In case of further doubts related to the use of this medicine, consult your doctor or pharmacist.
