I might have written that about Forteo. I haven't had side effects at all with Forteo. At 20mcg you are getting the same dose of PTH as Forteo. Both drugs lower your blood pressure as the PTH causes vasodilation. The vasodilation can cause headaches. And the dizzy lack of balance is from the low blood pressure.
I always hydrate before the injection and use it as an excuse to eat something salty.
There is a preservative in Tymlos that causes adverse reactions in some.
Some people really can't tolerate Forteo.
You could try taking the shot before bed.
Sometimes symptoms go away when your body adjusts. But two weeks with morning headaches? I wouldn't want to try and sleep with a headache either.
I hope it resolves. But I do think Forteo is the best osteoporosis drug.
