Medications during pregnancy


Hello Dr.
Jan: I visited the obstetrics and gynecology department at 20 weeks of pregnancy due to vaginitis.
The doctor informed me that I had an infection in the pelvic cavity and prescribed Ulecin antibiotics for me to take for a total of 14 days, but my discharge has not improved.
I am unsure if this medication has any effects on the fetus.

More Info


The use of antibiotics during pregnancy, particularly Ulecin (clindamycin), raises important questions regarding fetal health. Clindamycin is classified as a Category B drug by the FDA, which means that animal reproduction studies have not shown a risk to the fetus, and there are no adequate and well-controlled studies in pregnant women. This classification suggests that clindamycin is generally considered safe for use during pregnancy, especially when the benefits outweigh the risks.

In your case, you were prescribed Ulecin for a pelvic infection during your 20th week of pregnancy. It is crucial to treat infections during pregnancy, as untreated infections can lead to complications such as preterm labor, low birth weight, and even maternal health issues. Clindamycin is effective against certain types of bacteria, particularly anaerobic bacteria, which are often involved in pelvic infections.
The fact that you have been taking Ulecin for 14 days without improvement in symptoms is concerning, and it is essential to follow up with your healthcare provider. They may consider alternative treatments or further investigations to ensure that the infection is adequately addressed.
Regarding the potential impact of Ulecin on fetal health, studies have not reported significant adverse effects on fetal development when clindamycin is used during pregnancy. However, as with any medication, there can be individual variations, and it is essential to monitor for any unusual symptoms or side effects.
In addition to the safety profile of clindamycin, it is also important to consider the overall health of the mother and the fetus. Maintaining good maternal health through proper nutrition, hydration, and rest is vital during pregnancy. If you have concerns about the medication or your symptoms, do not hesitate to discuss them with your obstetrician. They can provide personalized advice based on your medical history and current condition.

In summary, Ulecin (clindamycin) is generally considered safe for use during pregnancy, particularly for treating infections that could pose a risk to both the mother and the fetus. However, it is crucial to monitor your symptoms and work closely with your healthcare provider to ensure the best possible outcome for both you and your baby. If you have any further questions or concerns, please reach out to your healthcare provider for guidance.
