Twynsta and Breastfeeding
Because no human studies have been done to determine if Twynsta (telmisartan/amlodipine) passes through breast milk, it is not known if this medication would harm a nursing infant. One of the components in this product has been shown to pass through breast milk in rats. Before taking Twynsta while breastfeeding, make sure to talk to your healthcare provider about the potential risks.
Is Twynsta Safe While Breastfeeding?It is unknown if Twynsta® (telmisartan/amlodipine) passes through breast milk. Therefore, it is not known if it is safe to take this medication while breastfeeding. If you are nursing a child, talk with your healthcare provider before taking Twynsta.
More Information on Breastfeeding and TwynstaTwynsta contains a combination of two medications -- telmisartan (Micardis®) and amlodipine (Norvasc®). Telmisartan has been shown to pass through the breast milk of rats; however, it is unknown if it passes through human breast milk. No research has been done to see if amlodipine passes through breast milk.
There have been two case reports of women using amlodipine while breastfeeding. In both of these reports, amlodipine did not seem to harm the nursing infant. However, it is not possible to determine if Twynsta is safe for use while breastfeeding based on this limited information.
In addition, there is no information available about the potential effects of telmisartan (the other component in Twynsta) in a nursing infant.
Although the lack of information about Twynsta and breastfeeding is certainly frustrating, it is important to keep in mind that studies are rarely done in breastfeeding infants. Such studies might put the infant, who would otherwise not directly benefit from the medication, at unnecessary risk.
