You can tell Imitrex® is a Serious Drug because it must be taken intravenously. I've seen the large, complex setup that comes with each dose, designed to hide the needle beneath a thick sheath of plastic before and during use, and after use to encase and destroy it irrecoverably. I guess the extra landfill mass is a small price to pay to keep the migraine sufferer's garbage from becoming a treasure trove for junkies.
