Some people have trouble swallowing tamoxifen in pill form or just prefer a liquid, so a liquid form of tamoxifen (brand name: Soltamox) is also available. If you dislike pills or you’re having trouble swallowing tamoxifen pills, Soltamox can help make it easier to stay on your treatment plan.

Soltamox (tamoxifen in liquid form) produces the same effect as pills and is the only liquid formulation approved by the U.S. Food and Drug Administration (FDA) to treat the same exact conditions:

  • women and men diagnosed with hormone-receptor-positive, early-stage breast cancer after surgery (or possibly chemotherapy and radiation) to reduce the risk of the cancer coming back (recurring)
  • women and men diagnosed with advanced-stage or metastatic hormone-receptor-positive disease

Tamoxifen also is used to:

  • reduce breast cancer risk in women who haven't been diagnosed but are at higher-than-average risk for disease

Tamoxifen won't work on hormone-receptor-negative breast cancer.

As with tamoxifen in pill form, you should not take liquid tamoxifen if you are breastfeeding, pregnant, trying to get pregnant, or if there is any chance that you could be pregnant. Tamoxifen may cause damage to developing embryos. You should use an effective non-hormonal type of birth control -- such as condoms, a diaphragm along with spermicide, or a non-hormonal I.U.D. – while you are taking tamoxifen and for 2 months afterward. Ask your doctor which type of non-hormonal birth control would be best for you.

Soltamox is available to patients who qualify at the same co-pay cost as generic tamoxifen. Patients can download a $10 co-pay per prescription card for unlimited use.
