Nodules are inflammatory lesions with a diameter of 5 mm or greater. The nodules may become suppurative or hemorrhagic. "Severe," by definition, means "many" as opposed to "few or several" nodules.

Isotretinoin Jenson description

sponsored

Isotretinoin Jenson is a medication used for the treatment of severe acne. It is sometimes used in prevention of certain skin cancers. It is a retinoid, meaning it derives from vitamin A and is found in small quantities naturally in the body. Isotretinoin Jenson binds to and activates nuclear retinoic acid receptors (RAR), thereby regulating cell proliferation and differentiation. This agent also exhibits immunomodulatory and anti-inflammatory responses and inhibits ornithine decarboxylase, thereby decreasing polyamine synthesis and keratinization.

Isotretinoin Jenson dosage

Isotretinoin Jenson (Isotretinoin Jenson) should be administered with a meal.

The recommended dosage range for Isotretinoin Jenson (Isotretinoin Jenson) is 0.5 to 1.0 mg/kg/day given in two divided doses with food for 15 to 20 weeks. In studies comparing 0.1, 0.5, and 1.0 mg/kg/day, it was found that all dosages provided initial clearing of disease, but there was a greater need for retreatment with the lower dosages. During treatment, the dose may be adjusted according to response of the disease and/or the appearance of clinical side effects — some of which may be dose related. Adult patients whose disease is very severe with scarring or is primarily manifested on the trunk may require dose adjustments up to 2.0 mg/kg/day, as tolerated. Failure to take Isotretinoin Jenson (Isotretinoin Jenson) with food will significantly decrease absorption. Before upward dose adjustments are made, the patients should be questioned about their compliance with food instructions.

The safety of once daily dosing with Isotretinoin Jenson (Isotretinoin Jenson) has not been established. Once daily dosing is not recommended.

If the total nodule count has been reduced by more than 70% prior to completing 15 to 20 weeks of treatment, the drug may be discontinued. After a period of 2 months or more off therapy, and if warranted by persistent or recurring severe nodular acne, a second course of therapy may be initiated. The optimal interval before retreatment has not been defined for patients who have not completed skeletal growth. Long-term use of Isotretinoin Jenson (Isotretinoin Jenson), even in low doses, has not been studied, and is not recommended. It is important that Isotretinoin Jenson (Isotretinoin Jenson) be given at the recommended doses for no longer than the recommended duration. The effect of long-term use of Isotretinoin Jenson on bone loss is unknown.

Contraceptive measures must be followed for any subsequent course of therapy.

Isotretinoin Jenson contraindications

See also:
What is the most important information I should know about Isotretinoin Jenson?

Hypersensitivity to Isotretinoin Jenson or to any of the excipients of Isotretinoin Jenson. Hepatic or renal insufficiency; hypervitaminosis A; patients with excessively elevated blood lipid values.

Use in pregnancy: Pregnancy Category X: Isotretinoin Jenson is highly teratogenic. It is, therefore, contraindicated not only in women who are pregnant or who may become pregnant while undergoing treatment but also in all women of childbearing potential. There is an extremely high risk that a deformed infant will result if pregnancy occurs while taking Isotretinoin Jenson in any amount even for short periods. Potentially all exposed foetuses can be affected.

Isotretinoin Jenson is contraindicated in women of childbearing potential unless the female patient meets all of the following conditions: Severe disfiguring cystic acne resistant to standard therapies; reliability in understanding and carrying out instructions; compliance with the mandatory contraceptive measures; informed by the physician of the hazards of becoming pregnant during and 1 month after treatment with Isotretinoin Jenson and warned of the possibility of contraceptive failure; confirms that patient has understood the warnings; negative pregnancy test within 2 weeks prior to beginning therapy, monthly repetition of pregnancy testing is recommended; use effective contraception without any interruption for at least 1 month before beginning Isotretinoin Jenson therapy, during therapy and for 1 month following discontinuation of therapy. At least 1 and preferably 2 complementary forms of contraception including a barrier method should be used. Microdosed progesterone preparations (minipills) may be an inadequate method of contraception during Isotretinoin Jenson therapy. If the patient starts Isotretinoin Jenson therapy only on the 2nd or 3rd day of the next menstrual period; in the event of relapse treatments, patient must also use the same uninterrupted and effective contraceptive measures 1 month prior to, during and for 1 month after Isotretinoin Jenson therapy; must fully understand the precautions and confirm patient understanding and willingness to comply with reliable contraceptive measures as explained.

Even female patients, who normally do not employ contraception because of a history of infertility, should be advised to do so while taking Isotretinoin Jenson, following the previously stated guidelines.

Should pregnancy occur inspite of these precautions during treatment with Isotretinoin Jenson or in the month following, there is a great risk of very severe malformation of the foetus (involving in particular the central nervous system, heart and large blood vessels). If pregnancy does occur, the physician and patient should discuss the advisability of continuing the pregnancy.

Major human foetal abnormalities related to Isotretinoin Jenson administration have been documented, including hydrocephalus, microcephalus, abnormalities of the external ear (micropinna, small or absent external auditory canals), microphthalmia, cardiovascular abnormalities, facial dysmorphia, thymus gland abnormalities, parathyroid hormone deficiency and cerebellar malformation. There is also an increased risk of spontaneous abortion.

Isotretinoin Jenson is highly teratogenic and must not be given to women who are pregnant. Isotretinoin Jenson crosses the placental barrier in amounts that lead to congenital deformities. There is an extremely high risk that a deformed infant will result if pregnancy occurs while taking Isotretinoin Jenson in any amount even for short periods. Potentially all exposed foetuses can be affected.
