I'm only using it for one thing, but I'm thrilled. I've been taking sumatriptan for migraines since 1990, about the time it became available in pill form. It was very expensive. Back then, my insurance mostly defrayed that. It stopped debilitating headaches.
Great! "One day, it will be generic," I thought.
For the next seventeen or so years, multiple doctors tried to switch me to newer drugs that weren't much different, just time-released or fast-dissolving. This would have extended the time to a generic version. Indefinitely, if I kept saying yes. "No, thank you. This one works."
At some point, I received a letter from my insurance company that said, "No matter what your doctor says, we will only cover eight pills a month." I've never received a letter about that about any other drug. It must have been REALLY expensive for them to cover it.
The generic date came. The price didn't go down, because the drug company sued. I had gone on COBRA after my divorce and it didn't cover prescriptions, so I was paying $200/month for those eight pills, but they prevented days of debilitating pain, so I forked it over. When they lost the suit, the price went down to generic levels, but I still only got eight pills a month and they'd gotten years of my money at the non-generic rate. I had became very skilled at deciding how bad I needed to feel before I took one of the precious jewels. (Also, I'd gotten prescription insurance again.)
We got new insurance last year, and suddenly I could only get 50 mg tablets for the generic price. My usual 100 mg tablets went up to $80/month. I could still only get eight. Tony said, "Have you tried Mark Cuban's outfit?"
Well, Mark Cuban sells me 30 pills/month, and they cost $12, including shipping. Just being free of worrying whether I'm going to run out is life-changing.
