What is the effect of Borymycin on fetal embryos?


Hello Dr.
Liu,
My girlfriend took Borymycin to treat acne before she became pregnant, and unexpectedly, our baby has arrived during this time; she is currently about three weeks pregnant.
However, she continued to take Borymycin without knowing she was pregnant, but she has stopped for over a week now.
Based on our calculations, she likely took Borymycin during the first two weeks of pregnancy, but I'm not sure about the dosage.
I am concerned whether this could cause any abnormal fetal development.

I have researched the side effects of Borymycin online, but since neither of us are medical professionals, we cannot determine the implications.
The dermatologist did not provide us with a clear answer; he only said it was up to us to decide whether to continue the pregnancy or not, and he left my girlfriend with a comment: if family members blame her, she should say the doctor advised her to terminate the pregnancy.

I am uncertain about the potential effects of this situation.
Although this child was an unexpected surprise, both of our families are already looking forward to the arrival, and we are planning to get married soon.
We really want to ensure the safe delivery of our first child, who will also be the first grandchild for our parents.

Could you please help us with this situation and provide some reassurance? Living in constant worry is not good for the baby.
Thank you very much!

To explain: In normal circumstances, there is still a 3% chance of congenital malformations occurring during pregnancy, even without the use of medications.
The U.S.
Food and Drug Administration (FDA) classifies drugs based on their effects on the fetus into categories A, B, C, D, and X.
Generally, drugs classified as A, B, or C can be used during pregnancy because no harmful effects on the fetus have been found in human trials or clinical studies.
The medication your girlfriend is taking, Borymycin (minocycline), falls under pregnancy category D, which is not recommended for use during pregnancy (especially after the 12th week) due to the potential impact on bone and dental development.
As for the use of minocycline in early pregnancy, there is a lack of medical literature reporting on its use during this stage, making it difficult to determine whether it increases the risk of congenital malformations.

More Info


The situation you are describing regarding the use of Borymycin (minocycline) during early pregnancy raises important concerns about the potential effects of medications on fetal development. It is understandable that you and your partner are feeling anxious about this unexpected pregnancy, especially considering the medication that was taken prior to and during the early stages of pregnancy.

Borymycin, which contains minocycline, is classified by the U.S. Food and Drug Administration (FDA) as a Category D drug for use during pregnancy. This classification indicates that there is evidence of risk to the human fetus based on adverse reaction data from investigational or marketing experience or studies in humans. Specifically, minocycline has been associated with potential risks to fetal development, particularly concerning the development of bones and teeth. The primary concerns include the possibility of discoloration of teeth and impaired bone growth if the drug is taken during the second and third trimesters of pregnancy.

In your case, since your girlfriend took Borymycin during the first few weeks of pregnancy, it is important to note that the critical period for organogenesis (the formation of organs) occurs during the first trimester, particularly from weeks 3 to 8. While there is limited data on the effects of minocycline during early pregnancy, the lack of definitive evidence does not entirely rule out the possibility of risks. The medical literature does not provide a clear consensus on whether the use of minocycline in early pregnancy significantly increases the risk of congenital malformations.

Given that your girlfriend has already stopped taking the medication and is now approximately three weeks pregnant, it is advisable to focus on regular prenatal care. Consulting with an obstetrician or a maternal-fetal medicine specialist can provide you with tailored guidance and monitoring throughout the pregnancy. They can assess the situation more thoroughly, considering your girlfriend's medical history, the specifics of the medication taken, and any potential risks.

It is also essential to maintain open communication with healthcare providers. If there are concerns about the baby's development, they may recommend additional ultrasounds or tests to monitor fetal health. Remember that many pregnancies proceed without complications, even when medications are taken inadvertently during early pregnancy.

In summary, while there are concerns associated with the use of Borymycin during pregnancy, the best course of action is to seek professional medical advice and ensure that your girlfriend receives appropriate prenatal care. It is understandable to feel anxious, but focusing on the present and taking proactive steps can help alleviate some of that worry. The support of family and friends, along with professional guidance, will be invaluable as you navigate this journey together.
