Precautions
It is very important that your doctor check your progress at regular visits to make sure that this medicine is working properly and to check for unwanted effects.
A woman should contact her doctor right away if she develops:
- Changes in vaginal discharge or
- Changes in vision or
- Coughing up blood or
- Leg swelling or tenderness or
- Menstrual irregularities or
- New breast lumps or
- Pelvic pain or pressure or
- Sudden chest pain or
- Unexplained shortness of breath or
- Vaginal bleeding
If you seek medical attention for any reason, be sure to tell your doctor that you take tamoxifen or have taken tamoxifen.
For women: Tamoxifen may make you more fertile. It is best to use some type of birth control while you are taking it. However, do not use oral contraceptives (“the Pill”) since they may change the effects of tamoxifen. Tell your doctor right away if you think you have become pregnant while taking this medicine.
