6.Contents of the package and additional information

Celestone Cronodose contains betamethasone. It is a corticosteroid (glucocorticoid) with anti-inflammatory properties. It is recommended for conditions that respond to treatment with injectable corticosteroids when a sustained effect is required(in its case, as a complement to the main treatment), and is especially useful in patients who cannot be treated with oral or local corticosteroids.

Celestone Cronodose is used for the treatment of:

By intramuscular route:

• Allergic, skin, rheumatic, and other conditions that respond to corticosteroids.

By local infiltration:

• Bursitis and inflammatory disorders associated with tendons (such as tenosynovitis); and inflammatory disorders of the muscle (such as fibrosis and myositis).

By intra-articular route:

• Rheumatoid arthritis andosteoarthritis.

By intradermal/intralesional route:

• Diverse skin conditions, in certain inflammatory and cystic disorders of the foot.

It should not be administered by intravenous or subcutaneous route.

Do not use Celestone Cronodose:

• If you are allergic to betamethasone or any of the other components of this medication (listed in section 6).
• If you have an infection (except if you are being treated for that infection).

Warnings and precautions

Consult your doctor, pharmacist, or nurse before starting to use this medication.

Inform all your doctors if you are taking or have recently taken glucocorticoids.

Your doctor will use the lowest possible dose of this medication to control the condition being treated and, whenever possible, will apply a gradual dose reduction.

Avoid abrupt discontinuation of treatment as it may cause a corticosteroid withdrawal syndrome that can persist for months after stopping this medication. Therefore, in situations of stress during this period, treatment should be re-established along with the necessary supply of salts and/or a mineralocorticosteroid.

If administered locally (intraarticularly), systemic unwanted effects may occur.

Administration of the medication by intramuscular injection should be carried out with special caution in patients with idiopathic thrombocytopenic purpura.

Repeated intraarticular injections may cause cartilage destruction and joint instability. Therefore, excessive use of a previously treated joint should be avoided.

Corticosteroids may mask the signs of an infection as well as increase the risk of contracting infections and/or make their diagnosis more difficult. Latent infections may be reactivated during the use of this medication.

This medication should not be injected into an infected joint previously. If septic arthritis (i.e., a significant increase in pain along with local swelling, restriction of joint mobility, fever, and general malaise) occurs and the diagnosis of sepsis is confirmed, appropriate antimicrobial treatment should be initiated.

Inform your doctor as it will be necessary to adopt precautions, such as closer monitoring of your condition, or additional therapeutic measures:

• If you have a history of tuberculosis or amebiasis, as it could cause reactivation of the disease; or if you have active tuberculosis or amebiasis.
• Immediately, in case of potential contact or exposure to chickenpox or measles.
• If you have fungal or parasitic infections.
• If you are to be vaccinated.
• If you are allergic to any medication.
• If you have diabetes.
• If you have osteoporosis (bone calcium loss), especially in postmenopausal women.
• If you have any psychiatric illness or history (in yourself or in your close relatives).
• If you have pheochromocytoma (a tumor of the adrenal gland).
• If you have cataracts, glaucoma (increased intraocular pressure), infections, or herpes simplex in the eye.
• If you have hypothyroidism or liver cirrhosis.
• If you have ulcerative colitis, inflammatory bowel disease, or peptic ulcers, esophagitis, renal insufficiency, heart failure, hypertension, myasthenia gravis (severe muscle weakness).

Contact your doctorif you experience blurred vision or other visual disturbances.

Especially with medium and high doses of corticosteroids, consider sufficient potassium supplementation and salt restriction in the diet; also monitor blood pressure and potassium levels.

This medication should not be administered epidurally.The safety and efficacy of epidural administration of corticosteroids have not been established.

This medication may produce a positive result in doping control tests.

The administration of corticosteroids may alter the value of some laboratory tests. Additionally, skin reactions in allergy tests may be masked.

Children and adolescents

In infants, children, and adolescents, the doctor will evaluate the benefits of treatment, especially in prolonged treatment with corticosteroids, as it may affect their growth and development. Therefore, in prolonged treatment with this medication, your doctor will closely monitor the growth and development of children and adolescents.

Use of Celestone Cronodose with other medications

Inform your doctor or pharmacist if you aretaking, havetakenrecentlyor may need to take any other medication, including those purchased without a prescription.

It may be necessary to adjust the dose of one of your medications and monitor for the appearance of adverse reactions. This is especially important if you are taking the following medications:

• Anfotericina B, as it may increase the risk of hypokalemia (low potassium levels).
• Antibiotics, as they significantly reduce the elimination of corticosteroids.
• Oral anticoagulants, as it may alter the desired effect of the anticoagulant.
• Antidiabetic medications, as you may need to adjust the dose.
• Tuberculosis medications, as it may decrease their blood levels.
• Medications used to treat heart disease, such as cardiac glycosides, as it may increase the risk of arrhythmias due to hypokalemia.
• Estrógenos (including oral contraceptives), as they may alter the action of this medication.
• Medications that induce liver enzymes (e.g., barbiturates, phenytoin, carbamazepine, rifampicin), as you may need to increase the dose of this medication.
• Medications against fungal diseases (ketoconazole), as they may increase the possible adverse effects of this medication.
• Some medications may increase the effects of Celestone Cronodose, so your doctor will perform close monitoring if you are taking these medications (including some for HIV: ritonavir, cobicistat).
• Nonsteroidal anti-inflammatory drugs (NSAIDs), as they may increase the risk of gastrointestinal adverse effects.
• Aminoglutetimida (medication for the treatment of certain tumors), as it may decrease the adrenal suppression effect induced by this medication.
• Anticholinesterase, as they may cause severe muscle weakness in patients with myasthenia gravis, which may require their withdrawal at least 24 hours before starting treatment with this medication.
• Somatropina (human growth hormone), as it may inhibit its response.

Interference with laboratory tests

If you are to undergo any laboratory test (including blood, urine, skin tests using allergens, etc.), inform your doctor that you are taking this medication, as it may alter the results.

Use of Celestone Cronodose with alcohol

The use of this medication with alcohol may increase the cases or severity of peptic ulcers.

Pregnancy,lactationand fertility

If you are pregnant or breastfeeding, or if you think you may be pregnant, consult your doctor or pharmacist before using this medication.

Pregnancy

Betamethasone crosses the placenta. During pregnancy, treatment should only be administered after weighing the risk-benefit ratio for both the mother and the fetus, even when used prophylactically beyond the 32nd week of gestation.

With prolonged treatment with corticosteroids during pregnancy, your doctor will closely monitor the child to identify signs of hypoadrenalism.

Corticosteroids are not indicated in the management of hyaline membrane disease after birth and should not be administered to pregnant women with preeclampsia, eclampsia, or evidence of placental damage.

Newborn babies of mothers who received Celestone Cronodose near the end of pregnancy may have low blood sugar levels after birth.

Lactation

Corticosteroids, including this medication, pass into breast milk and may delay growth, interfere with the production of the body's own corticosteroid, or cause other adverse effects. Therefore, caution should be exercised when administering this medication during lactation.

Fertility

In some patients, steroids may increase or decrease sperm motility and number.

Driving and operating machinery

The influence of this medication on the ability to drive and operate machinery is negligible or insignificant. Some adverse effects of this medication (such as muscle weakness or loss of muscle mass, psychiatric disorders (such as euphoria or depression), visual acuity decrease, increased intraocular pressure, or vertigo) may affect these activities, so be sure to check how you tolerate the medication before performing these tasks.

Use in athletes

This medication contains betamethasone, which may produce a positive result in doping control tests.

ADMINISTRATION INSTRUCTIONS

For intramuscular, intraarticular, intrasinovial, intralesional, or intradermal administration. Do not administer by intravenous or subcutaneous route.

This medicineshould not be injected into an unstable joint.

This medicine should be administered under aseptic conditions.

To restore the homogeneity of the suspension, shake the vial before opening it.

This medicine should not be used if a possible agglomeration or precipitation is observed (which could be due to exposure to freezing).

Once the necessary amount of the suspension has been loaded into the syringe, it should be injected immediately to avoid sedimentation.

• Intramuscular Administration:

Corticosteroids should be administered by deep intramuscular injection in the gluteal muscle to avoid local tissue atrophy.

• Intraarticular Administration:

Injections should be performed in the affected tendon sheaths and not in the tendons themselves. In periarticular inflammatory conditions, the injection should be performed in the painful area.

Intraarticular injection should be performed under aseptic conditions and with 22to24gaugeneedles.

The technique is as follows: the needle, adapted to an empty syringe, is introduced into the synovial cavity, and aspiration is performed. If synovial fluid is obtained, the puncture has been correct. Subsequently, the first syringe is replaced with another loaded with the necessary amount of the suspension, and the injection is performed.

Intraarticular injection of this medicine does not cause appreciable pain, nor has secondary exacerbation been reported, which sometimes occurs a few hours after intraarticular application of other corticosteroids.

• Intralesional and Intradermal Administration:

Intralesional treatment is performed by intradermal injection (not subcutaneously). A tuberculin syringe and a 1.5cm long, 25gaugeneedle will be used.

The medicine should be applied in such a way that it forms a uniform intradermal deposit.

Foot Diseases:In most cases, the medicine can be administered with a tuberculin syringe and a 2cm long, 25gaugeneedle.

Use with Local Anesthetics

Administration of the medicine by local route is well tolerated. However, if it is considered necessary to use local anesthetics, the suspension can be mixed in the same syringe with an equal amount of hydrochloride of procaine or lidocaine at 1or2% before proceeding with the injection. The necessary amount of the suspension is first transferred from the vial to the syringe, and then the anesthetic is introduced, shaking the syringe briefly. The anesthetic should not be introduced into the Celestone Cronodose vial. Formulations of anesthetics containing parabens should not be used.
