The doctor will also determine the lowest Labetalol dose in pregnancy that will work so that it is safe for you as well as the unborn baby.
2. Can Consuming Labetalol Cause The Baby To Be Born With Birth Defects?
Since most of the baby’s internal organs develop within the first 3 months (12 weeks) of pregnancy, any risk of birth defects will be higher at this time. Only a few studies have been conducted to identify if conditions like hypospadias or heart defects are linked to consumption of labetalol during pregnancy. The studies do not show any such link between labetalol and these defects at present.
3. Can Consuming Labetalol When Pregnant Cause Miscarriage?
One of the most common pregnancy-related issues is a miscarriage. It is the spontaneous loss of the baby in the first 20 weeks of pregnancy. Miscarriage due to the use of a particular drug is very rare.
There are no such assessments about miscarriage after consuming Labetalol. Very few evidence of miscarriages proves that it is one’s personal health status which is equally responsible for any such unfortunate eventuality.
4. Does Labetalol Cause Stillbirth?
Losing a baby is a terrible emotional blow. A baby who is born without any signs of life after 24 weeks of pregnancy, is called a stillborn child. The mother ‘s health, age, lifestyle, genetic factors are some of the reasons for it.
It is very difficult to say whether Labetalol causes stillbirth. There is a higher risk of stillbirth when high blood pressure of the pregnant age, lifestyle, genetic factors are some of the reasons mother is poorly controlled. Though there are cases where women are taking Labetalol experienced stillbirth, there are others who had a completely safe delivery. The effect of the high blood pressure that causes the risk of stillbirth and not Labetalol which alters the risk.
5. Does Labetalol Cause Preterm Birth (Before 37 Week), If Taken In Pregnancy?
Labetalol and pregnancy are absolutely common. Preterm delivery is sometimes medically induced by the doctor due to concerns about the baby’s health in the womb or because of the severity of the expectant mother’s high blood pressure. Therefore it cannot definitely be concluded that the medicines that are used to treat high blood pressure during pregnancy are actually responsible for the preterm delivery. Some studies of preterm birth rate were conducted in which it was found that taking Labetalol during pregnancy is not linked to an increased risk of preterm birth.
6. Can Consuming Labetalol In Pregnancy Cause Low Birth Weight?
It is quite a complicated question to affirm. Many of the studies that were conducted on the expectant mothers found no evidence that taking Labetalol during pregnancy increased the risk of low birth weight in the baby. Larger studies are much required to absolutely confirm that use of Labetalol during pregnancy does not cause low birth weight in the baby.
7. Can take Labetalol Cause other Health Problems in the Newborn Child?
It is absolutely uncertain whether labetalol dose in pregnancy can affect the baby after birth. There are some known side effects of Labetalol dose in pregnancy like low heart rate, low blood pressure, and low blood sugar. Sometimes these effects are found in babies who were exposed to Labetalol in their mother’s womb. However, a number of large studies have suggested that likelihood of any complication in the baby after birth is not due to the exposure of the baby to Labetalol in the mother’s womb. Therefore, mothers who have been taking Labetalol during pregnancy should arrange for the baby to be born at a unit where the baby can be well monitored and treated for a few hours or days after birth if required.
8. Is There Need Of Extra Monitoring For Me and Baby during Pregnancy or After Delivery?
When women with high blood pressure deliver their baby, they are usually offered special care and are closely monitored to ensure that their blood pressure is in the correct range and their baby is developing and growing at a normal pace. Most expectant mothers, as part of their antenatal care, are offered a scan at around 20 weeks of pregnancy to determine any birth defects in the fetus. Women who used Labetalol in the later stages of pregnancy should ensure appropriate medical intervention and support if the baby shows any signs of adverse effects of ‘beta blocker’ exposure.
Labetalol and pregnancy are not at all uncommon. One must also know that every pregnancy is unique. It is suggested to all expectant mothers to keep a record of all the medication undertaken during pregnancy in a handheld maternity record so that the doctor can see the medical history of the patient at a glance.
