There is no scientific evidence that lisinopril
may affect fertility
or cause difficulty in natural conception.
However, it is categorized as Class D drug by FDA for teratogenecity, i.e it may cause harm to the unborn fetus, and hence it is certainly advisable not to be on lisinopril and shift to aldomet
while trying for pregnancy
, as long as your blood pressure is well controlled on aldomet also.
