It promotes pancreatic insulin secretion by inhibiting the DPP-4 enzyme that degrades the intestinal hormone GLP-1 that is activated when eating (Baetta 2011, Scheen 2011).Oral administration, once daily.Very low risk of hypoglycemia. Doses 6 times higher than normal for 10 days or 4 times higher for 28 days do not produce side effects (EMA 2016). The most common side effect is rhinopharyngitis. Since the last update we have not found published data on its excretion in breast milk. Its pharmacokinetic data (EMA 2016, Scheen 2011): large volume of distribution, moderately high molecular weight and low liposolubility, make it unlikely that it will pass through to breast milk in significant amounts. Until there is more published data on this drug in relation to breastfeeding, safer known alternatives may be preferable, especially during the neonatal period and in case of prematurity. Diet, exercise, and breastfeeding improve blood sugar levels. Among the antidiabetics of this same group, Saxagliptin and Vildagliptin would be preferable due to their short half-life (less than 3 hours). See below the information of these related products:
CAS Number: 486460-32-6
No information is available on the clinical use of sitagliptin during breastfeeding. If sitagliptin is required by the mother, it is not a reason to discontinue breastfeeding. However, an alternate drug may be preferred, especially while nursing a newborn or preterm infant. Saxagliptin has a shorter half-life than the other dipeptidyl-peptidase IV inhibitors and linagliptin is highly protein bound, so these might be better choices among drugs in this class for nursing mothers.
During whole lactation period you shall first discuss with your doctor and then together you shall decide whether you shall take that drug or not however if you have already taken Januvia | Sitagliptin Tablet then you shall inform your doctor, But you should not be worried too much as Januvia | Sitagliptin Tablet comes in category of low risk drug.
Though Januvia | Sitagliptin Tablet dose not comes in category of safe drugs rather it comes in category of low risk but if your doctor is aware that you are breastfeeding your baby and has still recommended it then its advantages must be outweighing the risks.
