Compare Reclast vs. Nolvadex

Head-to-head comparisons of medication uses, side effects, warnings, and more.

Key takeaways

Reclast (zoledronic acid) and Tamoxifen (Nolvadex) are both prescription medications, but they serve different purposes and belong to different drug classes. Reclast is a bisphosphonate used to treat osteoporosis and Paget's disease, and it is administered as an intravenous infusion, typically once a year or every two years. In contrast, Tamoxifen is a selective estrogen receptor modulator (SERM) used to treat and prevent hormone receptor-positive (HR+) breast cancer, and it is taken orally, usually once a day. Reclast works by slowing down bone breakdown to increase bone strength, while Tamoxifen blocks estrogen from acting on breast cancer cells to stop their growth. Common side effects of Reclast include joint pain, fever, and headache, whereas Tamoxifen often causes hot flashes, vaginal discharge, and swelling in the arms and legs. Additionally, Tamoxifen has a risk of causing uterine cancer and blood clots, while Reclast can lead to severe jaw problems and kidney damage. Both medications have generic forms available.

Summary of Reclast vs. Nolvadex
Summary for Bisphosphonate
Prescription only
Reclast (zoledronic acid) is used to treat osteoporosis. It's only available as an intravenous (IV) infusion that's given at a clinic or your provider's office. The medication is an option for postmenopausal women with osteoporosis who can't take bisphosphonates by mouth or for those at very high fracture risk. Reclast (zoledronic acid) is a long-lasting medication, so the dosing isn't often (either one-time only, once a year, or once every 2 years). It can cause side effects like muscle and joint pain, headache, and fever. This medication is available under the brand name Reclast and as a generic.
