Count from the final dose
Use the date of your final prescribed capsule as day zero, then wait the full month required in the United States. Do not shorten the interval because your skin has improved or because you feel well.
If you cannot confirm the final-dose date, ask your prescriber or pharmacist to help you reconstruct it before trying to conceive.
Finish the post-treatment steps
Complete the follow-up pregnancy test and any remaining U.S. program steps on the schedule your prescriber gives you. A calendar reminder can keep the last-dose date, follow-up test, and one-month endpoint separate.
If pregnancy may have occurred sooner
If you think you may be pregnant during treatment or within the month after treatment, contact the isotretinoin prescriber promptly for exposure assessment and pregnancy counseling.
Frequently asked questions
Does the wait begin after my last appointment or my last capsule?
Count from the final prescribed dose. Ask your prescriber to confirm the date if your appointment and final capsule were on different days.
Can I stop pregnancy prevention as soon as I take the final capsule?
No. Continue the required pregnancy-prevention method for 1 month after treatment.
