1. What is Dexamethasone Krka and what is it used for

Dexamethasone Krka is a synthetic glucocorticosteroid. Glucocorticosteroids are hormones produced by the adrenal cortex. The described drug has anti-inflammatory, analgesic, and anti-allergic properties, as well as immunosuppressive effects.
Dexamethasone Krka is indicated for the treatment of rheumatic and autoimmune diseases (e.g., systemic lupus erythematosus, rheumatoid arthritis, juvenile idiopathic arthritis, giant cell arteritis), respiratory diseases (e.g., bronchial asthma, croup), skin diseases (e.g., erythroderma, common pemphigus), and tuberculous meningitis exclusively in combination with anti-infective therapy, blood diseases (e.g., idiopathic thrombocytopenic purpura in adults), brain edema, symptomatic treatment of multiple myeloma, acute lymphoblastic leukemia, Hodgkin's disease, and non-Hodgkin's lymphoma in combination with other medicinal products, palliative treatment of cancer, prevention and treatment of nausea and vomiting caused by chemotherapy, as well as prevention and treatment of postoperative nausea and vomiting together with antiemetic drugs.

2. Important information before taking Dexamethasone Krka

When not to take Dexamethasone Krka

• if the patient is allergic to dexamethasone or any of the other ingredients of this medicine (listed in section 6);
• in the case of a systemic infection (unless it is already being treated);
• in the case of gastric or duodenal ulcer disease;
• in the case of an upcoming vaccination with a live vaccine.

Warnings and precautions

If the patient is being treated for COVID-19, they should not stop taking any other steroid medications unless their doctor advises them to do so.
Before starting to take Dexamethasone Krka, the patient should discuss it with their doctor, pharmacist, or nurse:

• in the case of a history of severe depression or manic-depressive illness (bipolar affective disorder); this means having had depression before or while taking steroid medications like dexamethasone;
• if any close family members have had these illnesses.

Mental health problems can occur while taking steroids like Dexamethasone Krka.

• These disorders can be serious.
• They usually appear within a few days or weeks of starting to take the medicine.
• They occur more frequently after higher doses of the medicine.
• Most of these problems disappear after the dose is reduced or the treatment is stopped. However, if such problems occur, they may require treatment.

The patient should consult their doctor if they experience any symptoms of mental health problems while taking this medicine. This is especially important in the case of depression or suicidal thoughts. In a few cases, mental health problems have occurred after the dose was reduced or the medicine was stopped.
The patient should consult their doctor before taking the medicine if they have:

• kidney or liver disease (liver cirrhosis or chronic liver failure),
• a chromaffin tumor (adrenal gland tumor) or suspected chromaffin tumor,
• high blood pressure, heart disease, or a recent heart attack (there have been cases of heart rupture),
• diabetes or a history of diabetes in the family,
• osteoporosis (bone loss), especially in postmenopausal women,
• a history of muscle weakness caused by this or another steroid medication,
• glaucoma (excessive pressure in the eyeball) or a history of glaucoma or cataracts in the family (clouding of the lens in the eye leading to vision impairment),
• myasthenia gravis(a disease causing muscle weakness),
• gastrointestinal disease or stomach ulcers,
• psychiatric problems or mental illness that has worsened due to the use of this type of medication,
• epilepsy (a disease characterized by recurring losses of consciousness or seizures),
• migraine,
• hypothyroidism,
• parasitic infections,
• tuberculosis, sepsis, or fungal eye infections,
• cerebral malaria,
• herpes virus (oral or genital herpes as well as eye herpes, due to the possible perforation of the cornea),
• asthma,
• ongoing therapy for blocked blood vessels due to blood clots (thromboembolic disease),
• corneal ulcers and corneal injuries.

Taking this medicine can cause a chromaffin tumor to rupture, which can be fatal. A chromaffin tumor is a rare adrenal gland tumor. Rupture can manifest with the following symptoms: headaches, sweating, palpitations, and high blood pressure. If any of these symptoms occur, the patient should contact their doctor immediately.
Corticosteroid therapy can weaken the body's ability to fight infection. This can sometimes lead to the occurrence of infections caused by microorganisms that normally rarely cause infection (called opportunistic infections). If an infection occurs during treatment with this medicine, the patient should consult their doctor immediately. This is especially important in the case of signs of pneumonia: cough, fever, shortness of breath, and chest pain. There may also be a feeling of disorientation, especially in elderly patients. The patient should also inform their doctor about a history of tuberculosis or living in areas where parasitic infections are common.
While taking this medicine, it is essential to avoid contact with people who have chickenpox, shingles, or measles. If the patient suspects potential contact with any of these diseases, they should consult their doctor immediately. The patient should also inform their doctor about any history of infectious diseases, such as measles or chickenpox, and any vaccinations against these diseases.
The patient should consult their doctor if they experience any of the following conditions: symptoms of tumor lysis syndrome, such as muscle cramps, muscle weakness, confusion, vision disturbances, or loss of vision, and shallow breathing, in the case of a patient with a blood cancer.
If the patient experiences blurred vision or other vision disturbances, they should contact their doctor.
Treatment with this medicine can cause chorioretinopathy, an eye disease that impairs vision or causes vision disturbances. This usually affects one eye.
Therapy with this medicine can cause tendonitis. In extremely rare cases, tendon rupture can occur. This risk increases in the case of treatment with certain antibiotics and kidney problems. The patient should consult their doctor if they experience pain, stiffness, or swelling of the joints or tendons.
Taking Dexamethasone Krka can lead to a condition known as adrenal insufficiency. This can affect the effectiveness of the medicine in stressful situations or trauma, surgical procedures, childbirth, or illness, and the body may not be able to respond naturally to severe stress, such as accidents, surgery, childbirth, or illness.
If an accident, illness, or other special circumstances that physically stress the body occur during or after treatment with Dexamethasone Krka, the patient should inform the treating doctor about taking steroids.
In the case of suppression tests (detecting hormone levels in the blood), skin allergy tests, or bacterial infection tests, the patient should inform the person performing the tests about taking dexamethasone, as it may affect the test results.
During therapy, the doctor may also recommend reducing salt intake in the diet and potassium supplementation.
In the case of elderly patients, some side effects of taking this medicine may be more severe, particularly decreased bone density (osteoporosis), high blood pressure, low potassium levels, diabetes, increased susceptibility to infections, and thinning of the skin. The doctor will closely monitor the patient taking the medicine.

Children and adolescents
