Frequent use of acute migraine medications, like triptans, increases the risk of two problems that make headaches worse rather than better. First is tachyphylaxis: with repeated exposure, the drug’s effect can wane, so each attack may respond less well, nudging patients toward using more medication or dosing more often. Second is medication-overuse headache: regular use of triptans can trigger headaches on days when the drug isn’t used, or maintain a cycle of daily or near-daily headaches that persists because the brain’s pain pathways have been sensitized by the frequent meds. Limiting use to about 10 days per month minimizes these risks, helping preserve drug effectiveness and reduce the chance of chronic daily headaches. The other options aren’t the primary concern here—liver toxicity, kidney issues, or blood pressure effects are not the main reason for this dosing limit for trips.
