When it comes to understanding the dosage of Roaccutane (isotretinoin), it is crucial to follow a physician's guidance closely. Roaccutane is a powerful medication primarily used to treat severe acne, and its dosage is typically tailored to the individual based on factors such as body weight, severity of the condition, and previous treatment responses.

For a person weighing 70 kg, the common practice is to calculate the daily dosage based on a range of 0.5 to 1 mg per kg of body weight. This means that a daily dose could range from 35 mg (0.5 mg/kg) to 70 mg (1 mg/kg). Therefore, taking 20 mg three times a day would amount to 60 mg, which falls within this range. However, taking 20 mg four times a day would result in a total of 80 mg, which may be considered excessive and could increase the risk of side effects.

It's important to note that Roaccutane can have significant side effects, including but not limited to dry skin, chapped lips, and more serious effects like liver enzyme elevation and potential teratogenicity (risk of birth defects if taken during pregnancy). Therefore, exceeding the recommended dosage without medical supervision can be dangerous.

Regarding the cost of the medication, prices can vary widely based on the pharmacy, location, and whether you have insurance coverage. Since the specific 20 mg formulation is not available in your case, it would be best to consult with a local pharmacy or healthcare provider for accurate pricing.

In summary, while you can consider taking 20 mg three times a day based on your weight, it is essential to consult with your dermatologist or healthcare provider before making any changes to your medication regimen. They can provide personalized advice based on your medical history and current health status. Always prioritize safety and efficacy when it comes to medication management, especially with potent drugs like Roaccutane.
