1. What is Fortecortin and what is it used for

The dexamethasone phosphate contained in Fortecortin is a corticosteroid (glucocorticoid) derived from cortisone. It regulates many of the body's metabolic processes with anti-inflammatory and immunosuppressive activity.

Fortecortin is used by intravenous or intramuscular route for the treatment of:

• Inflammatory processes derived from brain tumors or cranioencephalic trauma.
• Traumatic shock (shock state after severe injuries).
• Anaphylactic shock (severe generalized allergic reaction).

2. What you need to know before you use Fortecortin

Do not use Fortecortin:

• If you are allergic or have had any allergic reaction to dexamethasone or any of the other components of this medicine (listed in section 6). These reactions are more common in patients with a history of allergy to any medicine.

• By intravenous administration if you have any systemic infection, unless you are receiving specific anti-infective treatment.

Warnings and precautions

Administration of Fortecortin may induce adrenocortical insufficiency, especially if high doses are administered for a prolonged period.

Avoid sudden withdrawal of treatment, especially in prolonged treatments, as a corticosteroid withdrawal syndrome may appear, characterized by general malaise, weakness, and muscle pain, difficulty breathing, loss of appetite, nausea, vomiting, fever, decrease in blood pressure and blood glucose levels.

In certain special situations of physical stress during treatment with Fortecortin (e.g., febrile disorders, accidents, operations, childbirth), a temporary increase in the daily dose of corticosteroid may be necessary.

Fortecortin may increase the risk of contracting infections as well as hiding the signs of an infection and/or making its diagnosis difficult. Latent infections may reactivate during the use of corticosteroids.

In the following cases, close monitoring of treatment by your doctor will be necessary:

• In acute and chronic bacterial infections.
• If you have lymph node inflammation (ganglia that help the body's defense) after being administered the tuberculosis vaccine.
• If you have a history of tuberculosis.
• Patients with chronic hepatitis (liver inflammation).
• Acute viral infections (hepatitis B, herpes, chickenpox, poliomyelitis, measles).
• Infections caused by fungi or parasites.
• If you need to be vaccinated or have been vaccinated between approximately 8 weeks before and 2 weeks after.
• If you suffer from diabetes, digestive ulcers, or inflammatory diseases of the digestive system, osteoporosis (calcium loss in bones), heart failure, high blood pressure, and psychiatric disorders.
• If you have glaucoma (increased intraocular pressure), corneal ulcers or injuries, blurred vision, or other visual disturbances.

Long-term treatment with Fortecortin will only be established when it is strictly necessary and should be associated with specific treatment corresponding to each case.

Administration of Fortecortin may alter the value of some laboratory tests.

Especially with long-term treatment with high doses of Fortecortin, sufficient potassium intake and restricted salt intake should be considered, and potassium levels in the blood should be monitored.

Administration of high doses of dexamethasone may cause a decrease in heart rate in some patients.

Severe anaphylactic reactions (immune system hyperreaction) may occur.

If you have myasthenia gravis (severe muscle weakness), it may initially worsen during treatment with Fortecortin.

If the intravenous administration of Fortecortin is too rapid, a sensation of tingling or numbness may appear, which can last for a few minutes.

If Fortecortin is administered locally (by intramuscular route), undesired systemic effects may occur.

In postmenopausal women, Fortecortin may increase the risk of osteoporosis.

You should inform your doctor if you have any of the following symptoms of tumor lysis syndrome (TLS) such as muscle cramps, muscle weakness, confusion, vision loss or alteration, and difficulty breathing, in case you suffer from a malignant hematological process.

Children and adolescents

In children, the doctor should assess the benefits of treatment, as the use of glucocorticoids may affect their growth. Dexamethasone should not be used routinely in premature newborns with respiratory problems.

If dexamethasone is administered to a premature baby, it is necessary to monitor the function and structure of the heart.

Elderly

In patients over 65 years of age, the doctor should assess the benefits of treatment and possible risks, as it is possible that these patients may suffer more adverse effects, such as osteoporosis.

Using Fortecortin with other medicines

Inform your doctor or pharmacist if you are taking or have recently taken any other medicine, including those obtained without a prescription, homeopathic medicines, herbal remedies, and other health-related products, as it may be necessary to interrupt treatment or adjust the dose of some of them. Note that these instructions may also apply to medicines used before or after.

This is especially important if you are taking the following medicines:

• Non-steroidal anti-inflammatory drugs (NSAIDs) such as indomethacin and salicylates, as they increase the risk of gastrointestinal ulcers and bleeding.
• Oral antidiabetics and insulin, as their effect may be reduced.
• Antiepileptics (carbamazepine), antiarrhythmics (phenytoin), bronchodilators (ephedrine), antitubercular antibiotics (rifampicin), barbiturates, and primidone, as they may decrease the effects of dexamethasone.
• Medicines that delay degradation in the liver, such as some antifungal medicines (ketoconazole, itraconazole) and certain antiretroviral medicines, as they may increase the action of corticosteroids. Therefore, your doctor will perform thorough checks if you are taking these medicines (including some for HIV: ritonavir, cobicistat).
• Coumarin derivatives (oral anticoagulants), as their anticoagulant effect may be modified.
• Estrogens (e.g., for contraceptive use) may increase the action of dexamethasone.
• Atropine and other anticholinergic medicines, as they may increase intraocular pressure.
• Medicines used to treat heart diseases, such as cardiac glycosides, as their effect may be increased by decreased potassium levels.
• Diuretics/laxatives, as they may increase potassium elimination.
• Praziquantel, as glucocorticoids may cause a decrease in praziquantel blood levels.
• Antihypertensive medicines (ACE inhibitors), as they may increase the risk of blood component alterations.
• Medicines against malaria (chloroquine, hydroxychloroquine, mefloquine), as they may increase the risk of muscle diseases or heart muscle diseases (myopathies, cardiomyopathies).
• Immunosuppressive substances, as they may increase the risk of infections. Additionally, in the case of cyclosporine, blood cyclosporine levels may be elevated, which increases the risk of cerebral convulsions.
• Non-depolarizing muscle relaxants, as muscle relaxation may be prolonged.
• Protirelin, as its effects on thyroid-stimulating hormone (TSH) may be affected.
• Fluoroquinolones, as they may increase the risk of tendon alterations.
• Amphotericin B, as it may increase the risk of decreased potassium levels (hypokalemia).
• Albendazole, as it may increase the levels of its active metabolite in the blood.
• Vaccines, as the immune response to the vaccine may be inadequate.

Pregnancy, breastfeeding, and fertility

If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor or pharmacist before using this medicine.

Pregnancy

Dexamethasone crosses the placenta. During pregnancy, especially in the first three months, treatment should only be administered after carefully weighing the risk/benefit ratio. Therefore, women should inform their doctor about an existing or suspected pregnancy. With long-term treatment with glucocorticoids during pregnancy, fetal growth disorders cannot be ruled out. If glucocorticoids are administered at the end of pregnancy, inadequate adrenal function may appear in the newborn, requiring substitution treatment with reduced doses in the newborn.

Newborns of mothers who received Fortecortin near the end of pregnancy may have low blood sugar levels after birth.

Breastfeeding

Glucocorticoids, including dexamethasone, pass into breast milk. So far, no harm has been reported in the infant. However, the need for administration during breastfeeding should be carefully examined. If high doses are necessary for medical reasons, breastfeeding should be interrupted. Consult your doctor immediately.

Fertility

The effects of Fortecortin on fertility have not been studied.

Driving and using machines

There are no data on how Fortecortin affects driving or operating machinery, so try not to perform tasks that require special attention until you verify how you tolerate the medicine.

Fortecortin contains sodium

This medicine contains less than 23 mg (1 mmol) of sodium per ampoule, so it is considered essentially "sodium-free".

Influence on laboratory tests

This medicine may alter the values of certain laboratory tests. Also, skin reactions in allergy tests may be masked.

Use in athletes

This medicine contains a component that may produce a positive result in doping tests.

3. How to use Fortecortin

Follow exactly the administration instructions of this medicine indicated by your doctor. Your doctor will set the doses individually. In case of doubt, consult your doctor or pharmacist again.

It should be taken into account that the dosage requirements are variable and should be individualized based on the disease and the patient's response.

Fortecortin is normally injected slowly (over 2-3 minutes) intravenously, but it can also be administered by intramuscular route. The dose and duration of treatment depend on the indication and severity of the disease to be treated. After obtaining an initial favorable response, your doctor will establish the most suitable maintenance dose for you. Reduction of the dose as well as suspension of treatment should always be done progressively.

Renal and hepatic insufficiency

No specific dose adjustment is necessary for patients with renal insufficiency.

In patients with hepatic insufficiency, comparatively lower doses may be sufficient, or the dose may need to be reduced.

Use in children and adolescents

Generally, the recommended daily dose in children is 0.08-0.3 mg/kg, depending on the severity and type of disease.

If you use more Fortecortin than you should

In case of overdose or accidental ingestion, consult your doctor or pharmacist immediately or call the Toxicology Information Service, phone: 91 562 04 20, indicating the medicine and the amount used.

No acute intoxications with dexamethasone are known. In the case of overdose, it is expected that the adverse reactions described in this leaflet will occur to a greater extent.

If you stop treatment with Fortecortin

Do not stop treatment before it is indicated by your doctor or suddenly, as it may worsen your disease.

Dose reduction should be done progressively. Similarly, treatment suspension should always be done progressively.

Excessive rapid reduction of the dose after long-term treatment may cause symptoms such as muscle and joint pain. Your doctor will gradually reduce the dose you should use.

If you have any other doubts about the use of this product, ask your doctor or pharmacist.
