hi, mamabear77,
teriparatide can cause low magnesium and low magnesium can cause low potassium.
Calcium, magnesium and potassium imbalance are implicated in muscle spasm and RLS.
Taking magnesium glycinate or citrate might help. The trouble with magnesium is that it can cause stomach discomfort. Magnesium glycinate is the easiest on the stomach.
You might have your electrolytes tested and consult with the prescribing physician.
Both Tymlos and Forteo work by causing transient elevation in serum calcium, and that may be throwing you off balance.
I hope you don't have to quit because I think Forteo the best available osteoporosis medication.
Unrelated to your question is this a link to a connect conversation about Nidra bands https://connect.mayoclinic.org/discussion/rls-and-the-nidra-bands/
Though, restless leg increase isn't noted as a common side effect, it is noted. Leg pain is common, but commonly abates within three months.
I've just begun my fourth year of Forteo without side effects, so I'm not the best source information.
I hope you won't have to quit because I think Forteo is the best available osteoporosis medication.
