Certain antidepressants when used by breast cancer survivors taking tamoxifen may cause the disease to return.
Researchers examined medical records and selected:
- 945 women taking the drug tamoxifen alone
- 353 women taking tamoxifen plus antidepressants. These took the combination for about a year.
Result: Breast cancer returned in 7% of women taking tamoxifen alone. Breast cancer returned 14 % of women taking the combination.
