Humulin R and Pregnancy
Based on what is known about Humulin R (regular insulin) and pregnancy, the medication appears to be safe for treating diabetes in pregnant women. Since both high blood sugar and low blood sugar can be dangerous to a fetus during pregnancy, it is important for pregnant women to control their blood sugar levels. If you are taking Humulin R and pregnancy occurs, notify your healthcare provider.
Humulin® R (regular insulin) is a medication used to treat diabetes. It is a short-acting form of insulin used to control blood sugar after meals. Humulin R is considered safe for treating diabetes in pregnant women.
The U.S. Food and Drug Administration (FDA) uses a pregnancy category system to classify the possible risks to a fetus when a specific medicine is taken during pregnancy. Pregnancy Category B is given to medicines that have not been adequately studied in pregnant humans but do not appear to cause harm to the fetus in animal studies.
It should be noted that Humulin R is identical to the insulin that is produced naturally in the human body. As long as blood sugar levels are appropriately controlled, Humulin R is considered to be quite safe for pregnant women.
Although it was originally thought that insulin molecules are too large to cross the placenta, it is now known that some insulins, in some circumstances, may cross the placenta. In general, most healthcare providers consider Humulin R to be safe for use during pregnancy. It is very important for pregnant women with diabetes (including gestational diabetes) to control their blood sugar, and Humulin R can be useful to help keep blood sugar under control.
Both high blood sugar (hyperglycemia) and low blood sugar (hypoglycemia) can be dangerous to the fetus during pregnancy. Therefore, very good blood sugar control is essential for a healthy pregnancy. Be sure to seek early prenatal care; as a pregnant woman with diabetes, you will likely require more care than the average pregnant woman.
