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. This medicine has anti-inflammatory, analgesic, and antiallergic properties, as well as immunosuppressive effects.
Dexamethasone Krka is indicated for the treatment of rheumatic and autoimmune diseases (e.g., muscle inflammation), skin diseases (e.g., common pemphigus), blood diseases (e.g., idiopathic thrombocytopenic purpura in adults), symptomatic treatment of multiple myeloma, acute lymphoblastic leukemia, Hodgkin's disease, and non-Hodgkin's lymphoma in combination with other medicinal products, metastatic spinal cord compression (spinal cord compression caused by a tumor), prevention and treatment of nausea and vomiting caused by chemotherapy, together with antiemetic drugs.

2. Important information before taking Dexamethasone Krka

Dexamethasone Krka should not be taken:

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

Warnings and precautions

Before taking Dexamethasone Krka, you should consult your doctor or pharmacist:

• if you have ever had severe depression or manic-depressive illness (bipolar affective disorder); this means having had depression before or while taking steroid medicines like dexamethasone;
• if any of your close family members have had these illnesses.

Mental health problems can occur during treatment with steroids like Dexamethasone Krka.

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

You should consult your doctor if you experience any symptoms of mental health problems while taking this medicine. This is especially important if you have depression or thoughts of suicide. In a few cases, mental health problems have occurred after reducing the dose or stopping treatment.
You should consult your doctor before taking the medicine if you have:

• kidney or liver disease (liver cirrhosis or chronic liver failure),
• chromaffin tumor (adrenal gland tumor) or suspected chromaffin tumor,
• hypertension, heart disease, or recent myocardial infarction (there have been cases of heart rupture),
• diabetes or a history of diabetes in the family,
• osteoporosis (bone mass loss), especially in postmenopausal women,
• a history of muscle weakness caused by this or another steroid medicine,
• glaucoma (increased pressure in the eyeball) or a history of glaucoma or cataracts in the family (lens clouding leading to vision impairment),
• myasthenia gravis(a disease that causes muscle weakness),
• bladder or stomach disease,
• psychiatric problems or mental illness that has worsened due to the use of this type of medicine,
• epilepsy (a disease characterized by recurring losses of consciousness or seizures),
• migraine,
• hypothyroidism,
• parasitic infections,
• tuberculosis, sepsis, or fungal eye infection,
• cerebral malaria,
• herpes virus (oral or genital herpes, as well as eye herpes, due to possible corneal perforation),
• 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 crisis, which can be fatal. Chromaffin tumor is a rare adrenal gland tumor. The crisis may manifest with the following symptoms: headache, sweating, palpitations, and hypertension. If any of these symptoms occur, you should contact your doctor immediately.
Corticosteroid therapy can weaken the body's ability to fight infection. This can sometimes lead to opportunistic infections caused by microorganisms that normally do not cause infection. If an infection occurs during treatment with this medicine, you should consult your doctor immediately. This is especially important in case of signs of pneumonia: cough, fever, shortness of breath, and chest pain. There may also be a feeling of disorientation, especially in the elderly. You should also inform your doctor about any history of tuberculosis or living in areas where parasitic infections are common.
During treatment with this medicine, it is essential to avoid contact with people who have chickenpox, shingles, or measles. If you suspect potential contact with any of these diseases, you should consult your doctor immediately. You should also inform your doctor about any history of infectious diseases, such as measles or chickenpox, and vaccinations against these diseases.
You should consult your doctor if you 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, if you have a blood disorder. If you experience blurred vision or other vision disturbances, you should contact your 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 with the use of certain antibiotics and kidney problems. You should consult your doctor if you experience pain, stiffness, or swelling of the joints or tendons.
Taking Dexamethasone Krka can lead to a condition known as adrenal insufficiency. It may affect the effectiveness of the medicine in situations of stress or injury, surgery, 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, and a procedure (even dental) or vaccination (especially with live virus vaccines) is necessary, you should inform the treating doctor about steroid use.
When performing suppression tests (detecting hormone levels in the blood), skin allergy tests, or bacterial infection tests, you should inform the person performing the test about dexamethasone use, as it may affect the test results.
During therapy, your doctor may also recommend reducing salt intake and potassium supplementation.
In elderly patients, some side effects of this medicine may be more severe, particularly bone density loss (osteoporosis), hypertension, low potassium levels, diabetes, increased susceptibility to infections, and skin thinning. The doctor will closely monitor the patient taking the medicine.

Children and adolescents

When using the medicine in children, it is essential for the doctor to closely monitor the child's growth and development at short intervals. Dexamethasone should not be used routinely in premature infants with respiratory failure.

This medicine should always be taken as directed by your doctor. If you are unsure, you should consult your doctor or pharmacist.
Dexamethasone Krka is available in 4 mg, 8 mg, 20 mg, and 40 mg tablet strengths. The tablets can be divided into halves, which provides additional strengths of 2 mg and 10 mg and allows the patient to swallow the tablet more easily.

Note that this is a high-dose medicinal product.

It is recommended to use Dexamethasone Krka in the lowest effective dose.

Dexamethasone is usually administered in doses of 0.5 mg to 10 mg per day, depending on the disease being treated. In more severe disease states, doses above 10 mg per day may be necessary. The dose should be determined based on individual patient response and disease severity. To minimize side effects, the lowest effective dose should be used.

If the doctor does not recommend otherwise, the following doses are recommended:

The dosing recommendations below are for informational purposes only.

Initial and daily doses should always be determined based on individual patient response and disease severity.

• -Pemphigus:initial dose of 300 mg for three days, followed by dose reduction according to clinical needs.
• -Muscle inflammation:40 mg for 4 days in a cycle.
• Idiopathic thrombocytopenic purpura:40 mg for 4 days in cycles.
• Metastatic spinal cord compression:initial dose and duration of treatment depend on the cause and severity of the disease. In palliative care, very high doses may be used, up to 96 mg. For optimal dosing and to reduce the number of tablets, tablets of lower strength (4 mg and 8 mg) can be combined with tablets of higher strength (20 mg or 40 mg).

For the prevention and treatment of chemotherapy-induced nausea and vomiting, in combination with other antiemetic medicines: 8-20 mg (one 20 mg tablet or half of a 40 mg tablet) before chemotherapy, and then 4-16 mg per day on the second and third days of therapy.

If not, you should follow national or international dosing protocols and guidelines. The prescribing doctor should carefully evaluate the appropriate dose in each case, considering the patient's condition and disease.
Long-term treatment
In the case of long-term treatment of several diseases, after initial therapy, it is recommended to switch from dexamethasone to prednisone or prednisolone to limit the suppressive effect on the adrenal cortex.
