Hi
I had gone through the question and understand your concern.
See , common side effects of Lupron Injection include redness/burning/stinging/pain/bruising at the injection site, hot flashes (flushing), increased sweating,
night sweats, tiredness, headache, upset stomach, nausea, diarrhea,
constipation, stomach pain, breast swelling or tenderness, acne, joint/muscle aches or pain, trouble sleeping (insomnia), reduced sexual interest, vaginal discomfort/dryness/itching/discharge, vaginal bleeding, swelling of the ankles/feet, increased urination at night,
dizziness, weakness, chills, clammy skin, skin redness, itching, or scaling,
testicle pain, impotence,
depression, or memory problems.
However , SVT is not even a rare side effect of Lupron injection. So , i would say you take Lupron injection as it does not precipitates your SVT.
I hope this information helps.
Let me know if you have any other queries.
Wish you good health
