{June 16, 2010}  

Therapeutic efficacy

Roaccutane and its side effects are dose dependent and vary among different patients. This requires individual selection of doses in the course of treatment.

Roaccutane Treatment should begin with the dose of 0.5 mg / kg body weight / Maintenance dose for most patients ranges from 0.5 do1.0 mg / kg body weight / In severe forms of disease or body acne daily dose may be increased to 2 mg / kg body weight .

It is proved that the frequency of remission and relapse prevention are optimal when using a cumulative dose of 120 mg / kg (for treatment). Therefore, the duration of therapy in specific patients varies depending on the daily dose. Complete remission of acne is often elusive for 16-24 weeks of treatment. When poor tolerability of the drug dose can be reduced, but the duration of treatment with the need to increase.

In most cases, for a course of therapy is sufficient for the complete disappearance of acne. When relapse is shown a second course of treatment Roaccutane in the same daily and cumulative dose, as the first. Since improvement may continue for up to 8 weeks after drug withdrawal, re-course should be appointed not earlier than after the end of this period. Capsules taken with food 1 or 2 In renal insufficiency, severe treatment should be started with lower doses (eg, 10 mg) and individually to select it, depending on tolerability.
