Sumatriptan (Imitrex) and other triptans have been available without a prescription in all European countries for over a decade. A new study by Austrian researchers published in the current issue of Headache confirms the outstanding safety of these drugs.
The study looked at 13,833 people over 50 years of age who were prescribed a triptan in 2011, the year before triptans became available over-the-counter. The comparison group included 41,400 triptan non-users. Of the 13,833, 19% were older than 65. The researchers established that 16% “overused” triptans, defined as getting more than 30 doses in a 90-day period, although the concept of “overuse” clearly lacks a scientific basis.
They discovered that those who were taking triptans did not spend more time in a hospital. They also did not have a higher frequency of heart attacks, hypertension, irregular heartbeats (arrhythmias), strokes, circulation problems in their extremities, or other vascular problems. This was true even for those who “overused” triptans.
These findings are consistent with the “Consensus Statement: Cardiovascular Safety Profile of Triptans in the Acute Treatment of Migraine” by the Triptan Cardiovascular Safety Expert Panel published in 2004. It states “The incidence of serious cardiovascular events with triptans in clinical trials and clinical practice appears to be extremely low “.
Unfortunately, in the US triptans are available only by prescription. About 15 years ago, the FDA blocked an application by the American Home Products (a company that Pfizer later acquired) to launch over-the-counter sumatriptan. This greatly restricts access to a highly effective and safe migraine drug. Many physicians remain under the impression that triptans cause heart attacks, strokes, and other dangerous side effects. My patients often tell me that this is what their previous doctor warned them about.
It is clear that triptans are safer than Excedrin, aspirin, ibuprofen, or naproxen. Several dozen of my patients have been taking triptans daily for years. They do not have medication overuse headaches, do not suffer any long-term side effects, and do enjoy disability-free life.
