Clonazepam in Pregnancy: Klonopin, Rivotril and Taper Checks
Published 2026-07-17 | By SafeMama Editorial Team | Editorial policy
Short answer
Clonazepam in pregnancy is a prescriber-guided risk-benefit decision. NHS says clonazepam can be taken during pregnancy when needed, especially for epilepsy, while MotherToBaby and DailyMed warn that late-pregnancy exposure can cause temporary newborn symptoms.
Prescriber-guided only
What is the safest way to think about this?
NHS says clonazepam can be taken during pregnancy when needed and that late-pregnancy use may make the baby drowsy or sleepy after birth. MotherToBaby says data on clonazepam alone are limited and that exposed newborns can have temporary symptoms such as breathing trouble, poor circulation or low muscle tone. DailyMed warns about neonatal sedation or withdrawal after late-pregnancy benzodiazepine exposure and about withdrawal after abrupt discontinuation. LactMed and NHS SPS advise caution during breastfeeding because clonazepam has a long half-life and may cause infant sedation, especially with other central nervous system depressants.

What is generally okay?
- Tell your obstetric clinician and the prescriber who manages clonazepam if you are pregnant, planning pregnancy or had unplanned exposure.
- Keep the reason for use, brand name, dose, frequency, last dose and any seizure or panic history ready for the appointment.
- Ask whether continuing, tapering, switching, extra fetal checks or newborn monitoring applies to your diagnosis and trimester.
- Review alcohol, opioids, sleep medicines, antihistamines, other benzodiazepines, seizure medicines and your breastfeeding plan before making changes.
What should you avoid or double-check?
- Avoid stopping clonazepam suddenly, especially with daily use, seizure treatment or long-term panic control.
- Avoid starting clonazepam, borrowing Klonopin or using Rivotril that was not prescribed for you.
- Avoid combining clonazepam with opioids, alcohol, sleep medicines or other sedatives unless your clinician specifically directs it.
- Avoid hiding late-pregnancy clonazepam use from the delivery team because the newborn may need monitoring.

Frequently asked questions
Is clonazepam safe in pregnancy?
It is not a simple yes or no. NHS says it can be taken when needed, especially for epilepsy, but your prescriber needs to weigh seizure or panic control, dose, trimester, other medicines and newborn monitoring.
What does clonazepam en el embarazo mean?
It means clonazepam in pregnancy. If you searched in Spanish, bring the medicine name, brand, dose and timing to your clinician or pharmacist rather than relying on translated internet advice.
Can I stop clonazepam after a positive pregnancy test?
Do not stop suddenly without medical advice. DailyMed warns that abrupt discontinuation after extended benzodiazepine use can cause withdrawal, and seizure treatment needs especially careful planning.
Can I taper clonazepam during pregnancy?
Possibly, but taper timing and speed should be designed by your prescriber. The plan depends on why you take clonazepam, how long you have used it and whether stopping could trigger seizures, panic or withdrawal.
Is Klonopin or Rivotril the same as clonazepam?
Yes. Klonopin and Rivotril are brand names for clonazepam in some markets. Check the active ingredient on the label and tell your clinician which brand and strength you use.
Is clonazepam used for seizures different from panic use?
Yes. The reason for treatment changes the risk-benefit discussion. Stopping a seizure medicine suddenly can be dangerous, while panic treatment still needs a careful plan for symptoms, sleep and withdrawal risk.
Can clonazepam affect the newborn?
Use near delivery can be associated with temporary newborn sedation or withdrawal symptoms. Tell the delivery team about dose and timing so the baby can be watched if needed.
Can I take clonazepam in the first trimester?
Ask the clinician who prescribed it and your pregnancy clinician. MotherToBaby says data on clonazepam alone are limited and have not shown an increased birth-defect chance in a small number of studies, but your own diagnosis and other medicines matter.
What medicines should not be mixed with clonazepam?
Avoid mixing clonazepam with alcohol, opioids, sleep medicines, other benzodiazepines or other sedatives unless your clinician specifically directs it. DailyMed warns that benzodiazepine and opioid combinations can cause dangerous sedation and breathing problems.
Is clonazepam safe while breastfeeding?
It needs individualized advice. NHS says it can usually be taken while breastfeeding if a clinician says the baby is healthy, but LactMed and NHS SPS recommend caution and infant monitoring for sleepiness, poor feeding, breathing changes and weight gain.
