Cumulative Dose Calculator

What is cumulative dose?

Cumulative dose is the total amount of Accutane (isotretinoin) taken over time, calculated as milligrams per kilogram of body weight (mg/kg). Providers use it to guide treatment length and reduce the risk of relapse.

The right cumulative dose helps:

  • Lower the chance of acne returning
  • Avoid under- or over-treatment
  • Support long-term clearance

How do I calculate my Accutane cumulative dose?

To calculate your cumulative dose, multiply your daily dose (mg) by the number of days you've taken it, then divide by your weight in kg. For example: (40mg × 180 days) ÷ 70kg = 103mg/kg. Our calculator does this automatically for you.

What is the target cumulative dose for Accutane?

The recommended target range is 150-220 mg/kg of body weight. Research shows this range provides the best treatment outcomes with the lowest risk of acne relapse. Honeydew follows these evidence-based guidelines.

How accurate is this Accutane calculator?

Our calculator uses the standard medical formula for cumulative dose calculation and is designed by healthcare professionals. However, it's for educational purposes - always consult your dermatologist for treatment decisions.

Can I use this calculator for isotretinoin?

Yes! Accutane is the brand name for isotretinoin. This calculator works for any isotretinoin medication, including generic versions and other brand names like Claravis, Absorica, or Myorisan.

What happens if I miss doses in my calculation?

If you miss doses, don't count those days in your calculation. Our calculator allows you to enter different monthly doses to account for changes or missed medication throughout your treatment.

How often should I check my cumulative dose?

It's helpful to check your cumulative dose monthly or at each dermatology appointment. This helps you and your provider track progress toward your target range and estimate remaining treatment time.

Is 150 mg/kg enough for Accutane treatment?

150 mg/kg is the minimum target for most patients. Many dermatologists prefer patients reach 150-220 mg/kg for optimal long-term results. Your specific target may vary based on your individual case and provider recommendations.

How does Honeydew help with Accutane treatment tracking?

Honeydew patients get automatic dose tracking built into their treatment platform. Our system calculates your cumulative dose in real-time, sends progress updates, and helps ensure you reach your optimal target range without manual calculations.
