mijas07,
I didn't have any side effects.
Within seconds of the injection the hormone pulls calcium from your bones, your digestive tract and back from your kidneys. You'll have about four hours of higher calcium levels.
Higher calcium levels dilate your blood vessels. More room in your blood vessels causes your blood pressure to drop and your heart to beat faster to keep the blood circulating at speed; It can cause a headache and/or nausea.
Salt and caffeine constrict your blood vessels. And extra fluids increase serum volume. I like a green olive and a glass of water before the injection. Tea or coffee might work even better, but not if you take the medication before sleep. If it did make you dizzy, you don't want to have to get up dizzy and half asleep.
If you inject in the morning just plan easy activities for the first few hours until you see how it affects you.
I was laughably cautious the first week, taking my blood pressure as fast as I could reset the cuff. I have low blood pressure usually 100/60, I'd lose 20 points on the systolic immediately, but I never felt anything.
Some do have allergic reactions to Forteo. But it is so easy to stop taking it. It leaves your system mostly in the first four hours.
It is a great drug to alert a patient to problems with their parathyroid glands or kidneys.
Mijas, it's good to use bone markers to make sure that Forteo is building bone. P1NP usually rises rapidly in the first two months. CTX will let you know if the effectiveness is lessening at a later point in time.
You might ask your physician to order CTX and P1NP before you start and two months in.
I hope Forteo will bless your bones. It's likely.
