Generic name: tamoxifen citrate
Written for women who use Soltamox™ to lower their high chance of getting breast cancer or who have ductal carcinoma in situ (DCIS)
This Medication Guide discusses only the use of Soltamox™ to lower the chance of getting breast cancer in high-risk women and in women treated for DCIS.
People taking Soltamox™ to treat breast cancer have different benefits and different decisions to make than high-risk women or women with ductal carcinoma in situ (DCIS) taking Soltamox™ to reduce the chance of getting breast cancer. If you already have breast cancer, talk with your doctor about how the benefits of treating breast cancer with Soltamox™ compare to the risks that are described in this document.
Why should I read this Medication Guide?
This guide has information to help you decide whether to use Soltamox™ to lower your chance of getting breast cancer.
You and your doctor should talk about whether the possible benefit of Soltamox™ in lowering your high chance of getting breast cancer is greater than its possible risks.
Your doctor has a special computer program or hand-held calculator to tell if you are in the high-risk group. If you have DCIS and have been treated with surgery and radiation therapy, your doctor may prescribe Soltamox™ to decrease your chance of getting invasive (spreading) breast cancer.
Read this guide carefully before you start Soltamox™. It is important to read the information you get each time you get more medicine. There may be something new. This guide does not tell you everything about Soltamox™ and does not take the place of talking with your doctor. Only you and your doctor can determine if Soltamox™ is right for you.
What is the most important information I should know about using Soltamox™ to reduce the chance of getting breast cancer?
Soltamox™ (tamoxifen citrate) is a prescription medicine that is like estrogen (female hormone) in some ways and different in other ways. In the breast, tamoxifen can block estrogen’s effects. Because it does this, tamoxifen may block the growth of breast cancers that need estrogen to grow (cancers that are estrogen- or progesterone- receptor positive).
Tamoxifen can lower the chance of getting breast cancer in women with a higher than normal chance of getting breast cancer in the next five years (high-risk women) and women with DCIS. Because high-risk women don’t have cancer yet, it is important to think carefully about whether the possible benefit of tamoxifen in lowering the chance of getting breast cancer is greater than its possible risks.
This Medication Guide reviews the risks and benefits of using Soltamox™ to reduce the chance of getting breast cancer in high-risk women and women with DCIS. This guide does not discuss the special benefits and decisions for people who already have breast cancer.
Why do women and men use Soltamox™?
Soltamox™ has more than one use. Soltamox™ is used:
This guide talks only about using Soltamox™ to lower the chance of getting breast cancer (#1 and #2 above).
What are the benefits of Soltamox™ to lower the chance of getting breast cancer in high-risk women and in women treated for DCIS?
A large U.S. study looked at high-risk women and compared the ones who took tamoxifen for 5 years with others who took a pill without tamoxifen (placebo). High- risk women were defined as women who have a 1.7% or greater chance of getting breast cancer in the next 5 years, based on a special computer program. In this study:
The study showed that on average, high-risk women who took tamoxifen lowered their chances of getting breast cancer by 44%, from 7 in 1,000 to 4 in 1,000.
Another U.S. study looked at women with DCIS and compared those who took tamoxifen for 5 years with others who took a placebo. In this study:
The study showed that on average, women with DCIS who took tamoxifen lowered their chances of getting invasive (spreading) breast cancer by 43%, from 17 in 1,000 to 10 in 1,000.
These studies do not mean that taking Soltamox™ will lower your personal chance of getting breast cancer. We do not know what the benefits will be for any one woman who takes Soltamox™ to reduce her chance of getting breast cancer.
What are the risks of Soltamox™?
In the studies described under "What are the benefits of tamoxifen?", the high- risk women who took tamoxifen citrate got certain side effects at a higher rate than those who took a placebo. Some of these side effects can cause death.
In one study, in women who still had their uterus:
These results show that, on average, in high-risk women who still had their uterus, tamoxifen doubled the chance of getting endometrial cancer from 1 in 1,000 to 2 in 1,000, and it increased the chance of getting uterine sarcoma. This does not mean that taking tamoxifen will double your personal chance of getting endometrial cancer or increase your chance of getting uterine sarcoma. We do not know what this risk will be for any one woman. The risk is different for women who no longer have their uterus.
For all women in this study, taking tamoxifen citrate tablets increased the risk of having a blood clot in their lungs or veins, or of having a stroke. In some cases, women died from these effects.
Tamoxifen increased the risk of getting cataracts (clouding of the lens of the eye) or needing cataract surgery. (See "What are the possible side effects of Soltamox™?" for more details about side effects.)
