Pregnancy: When used in pregnancy during the second or third trimesters, drugs that act directly on the renin-angiotensin system can cause injury and even death to the developing fetus. When pregnancy is suspected, Losartan Potassium + Hydrochlorothiazide (Kenzar Plus) should be discontinued as soon as possible.
Nursing Mothers: It is not known whether losartan is excreted in human milk. Thiazides appear in human milk. Because of the potential for adverse effects on the nursing infant, a decision should be made whether to discontinue nursing or discontinue the drug, taking into account the importance of the drug to the mother.
