Preventing Migraines

(Page 5)

Opioids

If migraine pain is very severe and does not respond to other drugs, doctors may try painkillers containing opioids. Opioid drugs include morphine, codeine, meperidine (Demerol), and oxycodone (Oxycontin)]. Butorphanol is an opioid in nasal spray form that may be useful as a rescue treatment when others fail.

Opioids are not approved for migraine treatment and should not be used as first-line therapy. Nevertheless, many opioid products are prescribed to patients with migraine, sometimes with dangerous results. For example, following reports of several drug-related deaths, the Food and Drug Administration warned that the cancer pain pill fentanyl (Fentora) should not be used to treat patients with migraine or others conditions for which the drug is not specifically approved.

Side Effects. Side effects for all opioids include drowsiness, impaired judgment, nausea, and constipation. There is a risk for addiction, and these drugs can become ineffective with long-term use for chronic migraines. Doctors should not prescribe opioids to patients at risk for drug abuse, including those with personality or psychiatric disorders.

Drugs Used for Nausea and Vomiting

Metoclopramide (Reglan) is used in combinations with other drugs to treat the nausea and vomiting that occurs with other drugs and with migraine itself. Metoclopramide and other anti-nausea drugs, such as domperidone (Motilium), may help the intestine better absorb migraine medications.
