Regarding females on Accutane, those of child-bearing age are required to be on two separate methods of birth control. However, if a male spouse of a female has received a vasectomy, this is only considered to be one single method of contraception for the female Accutane user.

In females, we are also required to test for pregnancy status monthly in compliance with I-Pledge.

However, if a male spouse of a female has received a vasectomy, this is only considered to be one single method of contraception for the female Accutane user.
Due the value of this drug, I-Pledge was developed as a governmental program to ensure that physicians prescribing the drug were following proper standards of care while administering the drug, that patients who took were in compliance with the regulations, and that the pharmacy where the drug was dispensed was in compliance as well. By the second month of Accutane, a patient has typically started to see improvement and, rarely clearance. Clearance will occur towards the end of the fifth month since the dosing is additive and weight-based.

To provide you with the most relevant and helpful information, and understand which information is beneficial, we may combine your email and website usage information with other information we have about you.For the past three decades, isotretinoin has been one of the most effective treatments on the market for severe acne. Since , the brand name Accutane has no longer been available on the market, and several other generic isotretinoin formulations have emerged.
This article will provide a summary of the use of isotretinoin for acne and examine the effects of dosing and diet on treatment efficacy. Isotretinoin is an oral retinoid indicated for the treatment of severe, recalcitrant, nodular acne not responsive to traditional therapies. Unlike other therapies, it addresses all of the known acne pathogenic factors, including sebum production, follicular hyperkeratinization, bacterial proliferation, and inflammation.
It is a lipophilic molecule, which enhances its penetration to the sebaceous glands. Moreover, absorption is influenced by dosing daily versus twice daily and by the presence of a fatty meal. For optimal absorption, isotretinoin must be taken with high-fat, high-calorie meals.
In the real world, where many patients do not even eat three meals a day, let alone high-fat, high-calorie meals, absorption of isotretinoin may be much lower. Moreover, many dermatologists are not educating patients on the true dietary needs of patients on this medication.
One study showed that percent of teenagers regularly skip meals. The goal of isotretinoin treatment is to give patients both a short-term improvement and long-term remission. Relapse rates are low, but re-treatment is not uncommon. Several risk factors for relapse have been identified. One study followed severe acne patients treated with isotretinoin for five years post-treatment.
Of relapsed patients, 17 percent required two courses, five percent required three courses, and one percent required more than three courses. One of the major, modifiable risk factors for relapse is insufficient dose. Prescribers must acknowledge that non-adherence to prescribed regimens and under-dosing are common. Patient-related factors cannot be controlled, but prescribers must make sure that the target cumulative doses are reached. Low doses of isotretinoin are often prescribed; patients cannot be discontinued after the standard weeks of therapy, as adequate cumulative drug levels will not have been reached.
Diet and number of doses per day can both affect drug absorption. Plasma levels of isotretinoin in the fasting state have been shown to be nearly 60 percent lower than levels in the fed state. In addition, trough levels of twice-daily dosing with isotretinoin actually exceed once-daily peak levels. Currently, 63 percent of prescriptions are for twice-daily dosing.
It is important to evaluate our patients with each visit to the office. If their skin and lips are not dry, they may not be satisfactorily absorbing their medication. Is the patient taking the medication? If so, is the patient absorbing it?
Why not? In addition to giving out a prescription, we must educate our patients on how to take the medication. High-fat, high-calorie meals maximize absorption, and twice daily dosing is superior to single dosing regimens, if your patient will be adherent with taking it.
