Can Concerta delay my period?

Question

Hello, I took my last contraceptive pill 10 days ago and I still have no period. Usually, I am very regular... I did a pregnancy test which was negative and nothing has changed (for/sport/stress) except that I started taking Concerta a month ago.

Hello Ma'am, I have found no indication that Concerta affects the menstrual cycle or the effects of birth control. When was the pregnancy test taken? Keep in mind that having a ''regular cycle'' on the pill does not indicate that your menstrual cycle will be regular when you stop taking the pill. It may take some people 3 to 6 months to become regular, but does not necessarily indicate a problem, especially in the absence of other symptoms. Cordially, Tom Samaha, pharmacist
