Dosage DECTANCYL 0.5 mg Tablet Box of 30

Oral way.

Anti-inflammatory equivalence (equipotence) for 5 mg prednisone: 0.75 mg dexamethasone

ADULT

The dosage varies according to the diagnosis, the severity of the condition, the prognosis, the patient's response and the tolerance to the treatment.

· Attack treatment: 0.05 mg / kg / day at 0.2 mg / kg / day (0.35 mg / kg / day at 1.2 mg / kg / day prednisone equivalent). As an indication: 6 to 24 tablets in an adult of 60 kg.

In severe inflammatory diseases, the dosage ranges from 0.1 to 0.2 mg / kg / day of dexamethasone (0.75 mg / kg / day to 1.2 mg / kg / day prednisone equivalent). As an indication: 12 to 24 tablets per day for an adult of 60 kg.

Very exceptional situations may require higher doses.

· Maintenance treatment: 0.5 to 1.5 mg / day, or 1 to 3 tablets daily.

CHILD

The dosage should be appropriate to the condition and weight of the child.

In children who can not swallow, the tablets will be crushed and mixed with the diet.

· Attack treatment: from 0.075 mg / kg / day to 0.3 mg / kg / day of dexamethasone (0.5 to 2 mg / kg / day prednisone equivalent). As an indication: 4 to 15 tablets for a child of 25 kg.

· Maintenance treatment: 0.03 mg / kg / day. As an indication 1 to 2 tablets for a child of 25 kg.

In the case of congenital adrenal hyperplasia, in case of failure of hydrocortisone, the dosage varies from 0.25 to 0.5 mg at bedtime (0.5 to 1 tablet per day).

The prescription of alternating day corticosteroid therapy (one day without corticosteroid and the second day with a daily double dose that would have been required) is used in children to try to limit stunting. This alternating day schedule can be considered only after the control of inflammatory disease by the high doses of corticosteroids, and when during the decay no rebound is observed.

IN GENERAL

Treatment at the "attack dose" should be continued until the disease is well controlled. Decay must be slow. Obtaining a weaning is the goal. Maintaining a maintenance dose (minimum effective dose) is a compromise that is sometimes necessary.

For prolonged treatment at high doses, the first doses can be divided into two daily doses. Thereafter, the daily dose may be administered as a single dose preferably in the morning during a meal.

Stop treatment

The rate of withdrawal depends mainly on the duration of treatment, the starting dose and the disease.

The treatment causes resting secretions of ACTH and cortisol with sometimes lasting adrenal insufficiency. When weaning, stopping should be done gradually, in stages because of the risk of relapse: reduction of 10% every 8 to 15 days on average.

For short courses of less than 10 days, stopping treatment does not require decay.

When decreasing doses (prolonged cure): at the dosage of 5 to 7 mg of prednisone equivalent, when the causal disease no longer requires corticosteroid treatment, it is desirable to replace the synthetic corticoid with 20 mg / day of hydrocortisone until recovery of corticotropic function. If corticosteroid therapy is to be maintained at less than 5 mg prednisone equivalent per day, a small dose of hydrocortisone can be added to achieve a hydrocortisone equivalent of 20 to 30 mg per day. When the patient is only under hydrocortisone, it is possible to test the corticotropic axis by endocrine tests. These tests do not eliminate the possibility of adrenal insufficiency during a stress.

Under hydrocortisone or even at a distance from arrest, the patient should be advised of the need to increase the usual dosage or to resume replacement therapy (eg 100 mg hydrocortisone intramuscularly every 6 to 8 hours) in case stress: surgery, trauma, infection.

Against indications

This drug is generally contraindicated in the following situations (there is, however, no absolute contraindication for life-threatening corticosteroid therapy):

· Any infectious condition, with the exception of the indications specified (see section Therapeutic indications ),

· Some developing viruses (including hepatitis, herpes, chickenpox, shingles),

· Psychotic states not yet controlled by a treatment,

· Live vaccines,

Hypersensitivity to dexamethasone or any of the excipients.

Dectancyl side effects

They are especially to be feared in important doses or during a prolonged treatment over several months.

· Hydroelectrolytic disorders: hypokalaemia, metabolic alkalosis, water-soluble retention, arterial hypertension, congestive heart failure.

· Endocrine and metabolic disorders: iatrogenic Cushing's syndrome, inertness of ACTH secretion, sometimes permanent adrenocortical atrophy, decreased glucose tolerance, revelation of latent diabetes, retarded growth in children, menstrual irregularities.

· Musculoskeletal disorders: Muscular atrophy preceded by muscle weakness (increased protein catabolism), osteoporosis, pathological fractures, especially vertebral compression, aseptic osteonecrosis of the femoral heads.

Some cases of tendon ruptures have been described in an exceptional way, in particular in co-prescription with fluoroquinolones.

· Digestive disorders: peptic ulcers, ulceration of the small bowel, perforations and digestive haemorrhages; acute pancreatitis has been reported, especially in children.

· Skin disorders: skin atrophy, acne, purpura, bruising, hypertrichosis, delayed healing.

· Neuropsychic disorders:

o frequently: euphoria, insomnia, excitement;

o rarely: manic pace, confusional or confuso-oniric states, convulsions (general or intrathecal);

o Depressive state when the treatment is stopped.
