Micardis-HCT should NOT be used during pregnancy. Telmisartan/hydrochlorothiazide can cause injury and death to the developing fetus. 

Tell your doctor if you are breastfeeding or plan to breastfeed. It is not known if telmisartan crosses into human milk, but hydrochlorothiazide is excreted in human breast milk. There is some evidence hydrochlorothiazide may reduce the amount of breast milk produced by women who take it. Because many medications can cross into human milk and because of the possibility for serious adverse reactions in nursing infants with use of this medication, a choice should be made whether to stop nursing or stop the use of this medication. Your doctor and you will decide if the benefits outweigh the risk of using Micardis-HCT.
