Can Medication Cause Late Period?

Yes, certain medications can cause a late or missed period. Some common types of medications that may affect the menstrual cycle include:

  1. Hormonal contraceptives: Birth control pills, patches, injections, and intrauterine devices (IUDs) can alter the menstrual cycle.
  2. Antipsychotics and antidepressants: Some medications used to treat mental health conditions can affect the hormonal balance and menstrual cycle.
  3. Chemotherapy: Cancer treatments can disrupt normal menstrual cycles.
  4. Thyroid medications: Thyroid disorders and the medications used to treat them can impact the menstrual cycle.
  5. Blood pressure medications: Some antihypertensive drugs may interfere with menstruation.
  6. Steroids: Both anabolic and corticosteroids can affect menstrual regularity.

Other factors, such as stress, significant weight changes, and underlying health conditions, can also contribute to a late period. If you’re concerned about a late period and suspect medication might be the cause, it’s best to consult with a healthcare provider.
