Does Methadone Cause High Blood Pressure?

Methadone is a medication for opioid use disorder. It’s not generally known to raise a person’s blood pressure. However, elevated blood pressure can be a symptom of methadone withdrawal.

Methadone withdrawal does not develop in people who are taking methadone as directed. Experiencing high blood pressure while taking methadone may be a sign of another health issue.

Increased Blood Pressure Caused By Methadone Withdrawal

Methadone is an opioid drug. Withdrawal from opioid drugs like methadone can cause a range of physical and psychological symptoms, including increased blood pressure.

What a normal blood pressure level looks like:

  • Less than 120 systolic mm Hg (upper number)
  • Less than 80 diastolic mm Hg (lower number)

Methadone withdrawal symptoms can occur if you miss a dose of methadone, or if you try to stop taking methadone too quickly after developing physical dependence.

Opioid withdrawal symptoms may also occur if the dose of methadone a person is taking is not sufficient to meet their needs. In this case, this may be something worth exploring with a doctor.

Can Methadone Cause Low Blood Pressure?

Methadone can cause decreased blood pressure, due to its depressant effects. Moreover, other factors, including the dose taken, may also influence a low blood pressure reading.

What can cause low blood pressure while taking methadone:

  • depressant effects on the nervous system
  • taking a very high dose of methadone
  • use of methadone with other CNS depressants
  • compromised ability to maintain blood pressure

People who plan to take methadone for opioid addiction should inform their doctor of any pre-existing health conditions, including hypotension or hypertension, prior to taking methadone.
