migraine
"Have been using orphenadrine  for migraine for several years. I use 100mg ER tablet with 1000mg acetaminophen. It is the only thing that has consistently worked on my migraines without major side effects. It is inexpensive and nonaddictive but not used much in the US. I had suffered for years with migraines, had been on atenolol with some decrease in the number but it exacerbated asthma. I discovered this medication while living in the Philippines and it has been a lifesaver. Fortunately I have migraines only 2 to 3 times per month. I do not know how it would work with intractable migraines."
