From the Research
Tamsulosin (Flomax) is generally considered compatible with breastfeeding, with limited data suggesting that very small amounts of the medication pass into breast milk, making the risk to a nursing infant minimal. The American Academy of Pediatrics classifies tamsulosin as usually compatible with breastfeeding 1, 2. If you need to take tamsulosin while nursing, you can continue to breastfeed your baby as normal. Tamsulosin works by relaxing muscles in the prostate and bladder neck, primarily treating urinary symptoms related to benign prostatic hyperplasia (BPH) in men, though it's occasionally used for urinary retention or kidney stones in women. Since tamsulosin is primarily prescribed for conditions affecting men, it's not commonly used during breastfeeding, which explains the limited research available.
Some key points to consider:
- The amount of medication that passes into breast milk is typically very small, and the risk to the infant is considered minimal 3, 4.
- If you're concerned, consider taking the medication immediately after breastfeeding to minimize exposure, and monitor your baby for unusual drowsiness or feeding difficulties.
- Always inform your healthcare provider that you're breastfeeding before starting any medication.
- While there is limited research on the use of tamsulosin during breastfeeding, the available data suggest that it is safe for use in nursing mothers 5.
It's essential to weigh the benefits and risks of taking any medication while breastfeeding, and to consult with your healthcare provider before making any decisions. However, based on the available evidence, tamsulosin (Flomax) can be considered safe for use during breastfeeding.
