Hi,
Concerta is used to treat attention deficit
hyperactivity disorder (ADHD). Concerta is a stimulant which increases attention and decrease impulsiveness and hyperactivity in patients with ADHD. Concerta can cause you to skip or delay periods as this can cause an elevated
prolactin level or an elevation in your thyroid function. Again, Concerta may cause loss of appetite or anorexia. Anorexia may cause
weight loss. Reduction of body weight can cause delayed
menstruation cycle, temporary cessation of menstrual cycle etc.
Even, naturally one or two menstrual periods may delay 7 days. It may happen without any specific reason. Do a pregnancy test 7-10 days after next missed period and consult your doctor. You can also undergo
thyroid function tests, s. prolactin level etc., to assess your hormonal status and exclude the causes.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Zubayer Alam, General And Family Physician
