You should not use Boniva if you have severe kidney disease or low levels of calcium in your blood.
Do not take a tablet if you have problems with your esophagus, or if you cannot sit upright or stand for at least 60 minutes after taking the tablet.
Boniva tablets can cause serious problems in the stomach or esophagus. Stop taking Boniva and call your doctor at once if you have chest pain, new or worsening heartburn, or pain when swallowing.
Also call your doctor if you have muscle spasms, numbness or tingling (in hands and feet or around the mouth), new or unusual hip pain, or severe pain in your joints, bones, or muscles.
