Warnings and precautions

Consult your doctor or pharmacist before starting to take this medication.

Depending on the doses and duration of treatment, induced adrenocortical insufficiency by glucocorticoids may persist for months and in individual cases up to one year after discontinuation of treatment. Acute adrenocortical insufficiency induced by therapy may be minimized by a slow reduction in dose if withdrawal is planned.

Treatment with this medication may increase the risk of infections and the diagnosis of the same may be more difficult. Latent infections (infections that did not show symptoms) such as tuberculosis or hepatitis B may be reactivated.

Long-term treatment with dexamethasone will only be established when strictly necessary and should be associated with specific treatment in each case.

In some cases, strict control of treatment by your doctor will be necessary.

You must inform your doctor if you have any of the following symptoms:

• Patients suffering from acute and chronic bacterial infections should receive specific antibiotic treatment, such as patients with a history of tuberculosis (infectious disease), who can only receive Fortecortín treatment under the protection of antitubercular drugs.
• In general, in patients who have received or are to receive any vaccine, particularly if lymph node inflammation (glands that help defend the body) is observed after receiving the vaccine for tuberculosis.
• In viral infections: hepatitis B, varicella, herpes, measles, poliomyelitis, herpetic keratitis. Special caution is recommended if you are immunocompromised or if you have not had measles or varicella and are in contact with people with measles or varicella.
• Infections caused by fungi or parasites.
• In patients with chronic hepatitis (inflammation of the liver).
• Difficult-to-control diabetes mellitus (increase in blood glucose).
• Osteoporosis (loss of calcium in bones).
• Severe heart failure.
• Difficult-to-control high blood pressure.
• Peptic ulcer.
• Inflammatory diseases of the digestive system.
• If you suffer from psychiatric diseases.
• If you have lymph node inflammation (glands that help defend the body) after being administered the tuberculosis vaccine.
• If you have glaucoma (increase in pressure within the eye) or eye ulcers.
• Symptoms of tumor lysis syndrome such as: muscle cramps, muscle weakness, confusion, loss or alteration of vision, and difficulty breathing, in the case of patients with malignant hematological disease.

Long-term treatment with this medication requires periodic medical control, including a vision check every 3 months.

Contact your doctor if you experience blurred vision or other visual disturbances.

The signs of peritoneal irritation due to gastrointestinal perforation may not appear if you are taking high doses of this medication.

If you take fluoroquinolones (substances with antibacterial activity) and corticosteroids (substances with anti-inflammatory properties), the risk of tendon alterations increases.

In cases of fever, accidents, operations, or childbirth, it may be necessary to temporarily increase the daily dose of this medication.

Severe allergic reactions may occur.

Treatment with this medication may exacerbate existing myasthenia gravis (a neuromuscular disease).

High doses of dexamethasone require adequate potassium supplements and dietary sodium restrictions; and plasma potassium levels should be monitored.

High doses of dexamethasone may cause a slower heart rate.

Children and adolescents

Fortecortín should not be used routinely in premature infants with respiratory problems.

Regular monitoring of the growth of children (see section 4) is necessary.

Older patients

In older patients, the doctor should evaluate the benefits and risks of treatment.

Other medications and Fortecortín 4 mg

The concomitant use of dexamethasone with any of the following medications may modify the effect of both dexamethasone and the medication in question:

• Estrogens (e.g. birth control pills),
• Enzyme inhibitors such as e.g. medications for fungal infections (itraconazole, ketoconazole, and amphotericin B),
• Antacids (e.g. aluminum hydroxide, magnesium hydroxide), the intake of these medications should be spaced two hours apart,
• Enzyme inducers such as e.g. medications for tuberculosis (rifampicin), medications for epilepsy (phenytoin, carbamazepine, and primidone),
• Sedatives (barbiturates),
• Central nervous system stimulants (ephedrine),
• Cardiac medications (digitalis),
• Antihypertensive medications or medications to promote urine elimination (diuretics),
• Laxatives,
• Oral antidiabetic medications or insulin,
• Anticoagulant medications. You may need to adjust the dose of the anticoagulant,
• NSAIDs or antirheumatic medications (e.g. indomethacin or salicylates), which increase the risk of gastrointestinal ulcers and bleeding,
• Medications that relax muscle used for the relief of spasms or contractions of the stomach, intestines, and bladder (rocuronium, vecuronium, atropine, or other anticholinergic medications),
• Antiparasitic medication (praziquantel),
• Malaria medications (chloroquine, hydroxychloroquine, mefloquine), which may increase the risk of myopathy and cardiomyopathy (muscle or heart muscle diseases, respectively),
• Growth hormone (somatotropin),
• Thyroid function diagnostic medications (protirelin),
• Immunosuppressive medications and cyclosporine (medications to prevent organ rejection after transplantation),
• Some antibiotics (fluoroquinolones), which may increase the risk of tendon alterations.
