Tamoxifen works by blocking estrogen receptors in breast tissue. While estrogen may not actually cause breast cancer, it is necessary for the cancer to grow in estrogen receptor-positive breast cancers. With estrogen blocked, the cancer cells that feed off estrogen may not be able to survive.

How to Take Tamoxifen

Tamoxifen is available in tablet form to be taken orally (by mouth). It should be taken around the same time every day. This medication should be swallowed whole with a full glass of non-alcoholic liquid. Do not crush, chew or break the tablets. A liquid version (Soltamox®) of this medication is also available. Talk with your provider if you have trouble swallowing pills. If you miss a dose take it as soon as you remember. If it is close to your next scheduled dose do not double your dose, rather skip the missed dose and continue your regular schedule.

It is important to make sure you are taking the correct amount of medication every time. Before every dose, check that what you are taking matches what you have been prescribed.

The blood levels of this medication can be affected by certain medications and supplements. These include: warfarin, paroxetine, fluoxetine, and amiodarone among others. Make sure your providers are aware of all medications (over-the-counter and prescription) and supplements you are taking.
