Drugs Home > Talwin and Breastfeeding

Talwin (pentazocine) is thought to pass through breast milk. However, it is not exactly clear how this drug may affect a nursing infant. Using Talwin for long periods of time while breastfeeding is likely to increase the risk for problems in an infant rather than using the drug intermittently. To help minimize problems, talk to your healthcare provider before beginning treatment.

Can Breastfeeding Women Use Talwin?

Talwin® (pentazocine lactate) is a prescription medication used before surgery or anesthesia, or to treat moderate-to-severe pain. It is thought to pass through breast milk. Therefore, if you are breastfeeding or plan to start, talk to your healthcare provider before using Talwin.
 

More Information on Talwin and Breastfeeding

Talwin has not been adequately studied in breastfeeding women. Based on the properties of the medication, it is expected to pass through breast milk to some extent. However, the effects of the drug on a nursing infant are currently unknown.
 
According to some experts, infrequent use of Talwin in small doses is unlikely to cause any substantial problems during breastfeeding. However, other sources state that other medications are preferred due to the lack of information on the use of using Talwin while nursing. In general, the chronic use of Talwin would probably be more likely to cause problems in a breastfeeding infant than intermittent use.  
 
If your healthcare provider recommends breastfeeding while using Talwin, make sure to carefully watch your child for any potential side effects and report them immediately to your child's healthcare provider. Some of these possible side effects may include:
 
  • Unusual sleepiness
  • Breathing problems
  • Difficulty feeding
  • Limpness.
