Sumatriptan Injection Site (Low BF%) in General Board Posted December 10, 2019 This is from the American Headache Society, 2018, regarding Indomethacin for hemicrania: >>>Indomethacin (Indocin) is a medication that ﬁghts inﬂammation, similar to ibuprofen or naproxen, but indomethacin is unique in that it is the only medication that functions as a key in the lock to stop HC. Usually indomethacin is started at a low dose, such as 25 mg, taken 3 times per day with meals. The dose is then increased until the head pain is relieved. Doses can sometimes reach 75 mg 3 times per day or more before the pain is fully blocked. When taking this medication, stomach protection against ulcers and bleeding is generally required. Proton pump inhibitors, such as omeprazole or lansoprazole, or H2 receptor antagonists, such as ranitidine or famotidine, can provide such protection. Most people tolerate indomethacin, particularly in lower doses. Unfortunately, others are unable to tolerate indomethacin at all, or in the doses needed to relieve their pain.<<< https://americanheadachesociety.org/wp-content/uploads/2018/05/Hemicrania_Continue_June_2015.pdf I'm not saying you should be taking it or shouldn't; just that this seems to be what's needed to give it a reasonable test (and possibly tolerate it).
