Can I take this if I am pregnant or trying to get pregnant or if I am breastfeeding?

Lisinopril has been assigned to pregnancy category D by the FDA for use during the second and third trimesters and to category C during the first trimester. Animal and human data have revealed evidence of embryolethality and teratogenicity associated with ACE inhibitors. There are no controlled data in human pregnancy. Congenital malformations have been reported with the use of ACE inhibitors during the first trimester of pregnancy, while fetal and neonatal toxicity, death, and congenital anomalies have been reported with the use of ACE inhibitors during the second and third trimesters of pregnancy. If the patient becomes pregnant, lisinopril should be discontinued as soon as possible. Lisinopril is considered contraindicated during pregnancy.

Drugs that act directly on the renin-angiotensin system can cause fetal and neonatal morbidity and death when administered during pregnancy. A committee of the National Institutes of Health has recommended that these drugs be avoided during pregnancy. Limited data have shown an association between major congenital malformations and the use of ACE inhibitors during the first trimester. In addition, the use of drugs that act directly on the renin-angiotensin system during the second and third trimesters of pregnancy has been associated with fetal and neonatal injury, including hypotension, neonatal skull hypoplasia, anuria, reversible or irreversible renal failure, and death. Oligohydramnios has also been reported, presumably resulting from decreased fetal limb contractures, craniofacial deformation, and hypoplastic lung development. Prematurity, intrauterine growth retardation, and patent ductus arteriosus have also been reported, although it is not clear whether these occurrences were due to exposure to the drug. Mothers whose embryos and fetuses are exposed to an ACE inhibitor during the first trimester should be informed of the risks. When pregnancy is detected or expected, lisinopril should be discontinued as soon as possible.

There are no data on the excretion of lisinopril into human milk. The manufacturer recommends that due to the potential for serious adverse reactions in nursing infants, a decision should be made to discontinue nursing or discontinue the drug, taking into account the importance of the drug to the mother.

I am on so many medications; do I have to take them all?
This is called polypharmacy—many different medications being used at the same time by one person. Sometimes, being on multiple medications is acceptable and appropriate but at other times it may be problematic. If you are receiving your medications from multiple physicians you need to ensure that they all know what medications you are taking. The best way to do this is to make a list of all the medications you are currently using, including all nutritional supplements, homeopathic remedies, vitamins and over-the-counter drugs (if possible, also include all the diseases you have been diagnosed with). Give a copy to every doctor who takes care of you so they have it on file, this way they can avoid duplicating medications and perhaps even try to consolidate some. After every doctor's visit remember to update the list accordingly. Also, as much as you possibly can, try to use the same pharmacy to fill all your prescriptions, this way any potential drug interactions can be caught and averted.
