Soltamox Overview

Updated: 

Soltamox is a prescription medication used to treat breast cancer as well as lower the chance of developing breast cancer in certain populations. Certain types of breast cancers require estrogen to grow. Soltamox belongs to a group of drugs called anti-estrogens which can block estrogen’s effects, slowing the growth of cancer cells. 

Soltamox comes in an oral solution form and is usually taken once or twice a day, with or without food. 

Soltamox is usually taken for 5-years, unless your doctor tells you otherwise. 

Common side effects of Soltamox include hot flashes, altered menstrual period timing, and vaginal discharge.

Soltamox can also cause dizziness. Do not drive or operate heavy machinery until you know how Soltamox affects you.

Soltamox and Pregnancy

Tell your doctor if you are pregnant or plan to become pregnant.

The FDA categorizes medications based on safety for use during pregnancy. Five categories - A, B, C, D, and X, are used to classify the possible risks to an unborn baby when a medication is taken during pregnancy.

Soltamox falls into category D. In animal studies, pregnant animals were given this medication and had some babies born with problems. There are no adequate and well-controlled studies done in humans. Soltamox can cause harm to your unborn baby. 

Women should not become pregnant while taking Soltamox or within 2 months of stopping Soltamox. Women should use contraception while taking Soltamox and for 2 months after stopping Soltamox. It takes about 2 months to clear Soltamox from your body. To be sure you are not pregnant, you can start taking Soltamox while you are having your menstrual period. Or, you can take a pregnancy test to be sure you are not pregnant before you begin. If you get pregnant while taking Soltamox, stop taking it right away and contact your doctor. Soltamox may harm your unborn baby.

Soltamox and Lactation

Tell your doctor if you are breastfeeding or plan to breastfeed.

It is not known if Soltamox crosses into human milk. Because many medications can cross into human milk and because of the possibility for serious adverse reactions in nursing infants with use of this medication, women taking Soltamox should not breastfeed.

Soltamox comes in an oral solution form and is usually taken once or twice a day. Take with or without food.

If you miss a dose, take the missed dose as soon as you remember. If it is almost time for the next dose, skip the missed dose and take your next dose at the regular time. Do not take two doses of Soltamox at the same time.

Other Requirements

  • Have regular gynecology check-ups, breast exams and mammograms. Your doctor will tell you how often. These will check for signs of breast cancer and cancer of the endometrium (lining of the uterus). Because Soltamox does not prevent all breast cancers, and you may get other types of cancers, you need these exams to find any cancers as early as possible.
  • Tell all of the doctors that you see that you are taking Soltamox.
  • Tell your doctor right away if you have any new breast lumps.
  • Store at temperatures up to 25°C (77°F).
  • DO NOT freeze or refrigerate.
  • Store in original packaging in order to protect from light. Use within 3 months of opening.
  • Keep this and all medicines out of reach of children.

Soltamox FDA Warning

For women with a condition called Ductal Carcinoma in Situ (DCIS) and women at high risk for breast cancer:

Serious and life-threatening events have been associated with Soltamox in the risk reduction setting (women at high risk for cancer and women with DCIS) include uterine cancers, stroke and lung blood clots. Uterine cancers can consist of both endometrial adenocarcinoma and uterine sarcoma. Some of the strokes, blood clots, and uterine malignancies seen in clinical trials were fatal.

Health care providers should discuss the potential benefits versus the potential risks of these serious events with women at high risk of breast cancer and women with DCIS considering Soltamox to reduce their risk of developing breast cancer.

The benefits of Soltamox outweigh its risks in women already diagnosed with breast cancer.
