Is there a correlation between missed periods and Suboxone (buprenorphine/naloxone) use?

Correlation Between Missed Periods and Suboxone (Buprenorphine/Naloxone)

Yes, there is a correlation between missed periods and Suboxone (buprenorphine/naloxone) use, as opioid medications including buprenorphine can affect the hypothalamic-pituitary axis and lead to menstrual irregularities.

Mechanism of Action

• Opioid medications, including buprenorphine (the active component in Suboxone), can influence the hypothalamic-pituitary axis, affecting hormone production and potentially leading to menstrual irregularities 1
• Similar to other medications that interact with hormonal systems, buprenorphine can alter metabolism of hormones and binding proteins, potentially disrupting normal menstrual cycles 1
• The effects on menstrual cycles are similar to those seen with other medications that affect the endocrine system, such as certain antiepileptic medications which have been documented to cause menstrual irregularities 1

Clinical Evidence

• Studies examining medication effects on hormonal systems have demonstrated that drugs affecting the central nervous system, including opioids like buprenorphine, can cause secondary endocrine complications including menstrual irregularities 1
• While specific research on Suboxone and menstrual cycles is limited, the medication's opioid properties are known to potentially affect hormonal regulation 1
• Medications that affect hormonal balance can cause cycle irregularities ranging from missed periods (amenorrhea) to irregular bleeding patterns 1

Management Considerations

• For women experiencing missed periods while on Suboxone, monitoring hormonal status may be warranted if irregularities persist 2
• Hormonal contraceptives may help regulate menstrual cycles in women experiencing irregularities while on Suboxone therapy 2
• Extended or continuous hormonal contraceptive regimens may be particularly beneficial for conditions exacerbated by hormonal fluctuations, including those caused by medications like Suboxone 1

Important Considerations for Women on Suboxone

• Women on Suboxone therapy should be informed about the possibility of menstrual irregularities as a potential side effect 1
• Regular follow-up is recommended to assess for menstrual irregularities and other potential hormonal effects 2
• If a woman on Suboxone therapy experiences persistent menstrual irregularities, evaluation for other potential causes should still be considered 2

Pregnancy Considerations

• For women with opioid use disorder who become pregnant while on Suboxone, recent research indicates that buprenorphine with naloxone appears to be a safe treatment option during pregnancy 3
• A 2024 study found similar and sometimes more favorable neonatal and maternal outcomes for pregnancies exposed to buprenorphine combined with naloxone compared with buprenorphine alone 3
• This supports flexibility in treatment decision-making for women with opioid use disorder who are pregnant or planning pregnancy 3

Clinical Approach

• If a woman on Suboxone reports missed periods, consider:
  • Ruling out pregnancy first (most important immediate step) 2
  • Evaluating for other potential causes of amenorrhea if pregnancy test is negative 2
  • Considering hormonal contraception to help regulate cycles if appropriate 2
  • Maintaining effective Suboxone treatment while addressing menstrual concerns 4

Common Pitfalls to Avoid

• Don't automatically attribute missed periods solely to Suboxone without ruling out other common causes including pregnancy 2
• Avoid unnecessarily discontinuing effective Suboxone treatment due to menstrual irregularities, as discontinuation rates are already high and can lead to relapse 4
• Don't overlook the importance of discussing potential menstrual irregularities when initiating Suboxone treatment in women of reproductive age 1
