Dear Midwife,
Hi ! Thank you for giving me the opportunity to ask you about a problem that really really bothers me.

I am pregnant in 24/25 weeks and a manage to stay pregnant (as first pregnancy as well, my boy is 4 years old) taking tocolitics like no- spa and progesterone ,until 20 week of pregnancy.

My real problem is that some how (I don't know how) I was positive for VDRL test 2 years ago and a followed some treatment but I don't know if it was effective because on my 16 week of pregnancy I had a positive VDRL , unknown tires. I followed treatment with benzanthile penicillin 2x 1,2 mil units , repeated after a week. Now my doctor told me that I have much amniotic fluid . My VDRL tests are uncertain and I decided to start again a session of treatment with benzanthile penicillin 2x 1,2 mil units , repeated 2 weeks . Now I've got the fist shot 2x1.2mil .

I am very scared not to harm may baby , isn't so much penicillin toxic ? I've read some article that said that this type of penicillin causes hart defects on fetus ? Please help me


Benzathine penicillin is Pregnancy Category B, so no worries there, as far as I know. But if you have ever had a positive VDRL, it is not uncommon that you will always have one from then on, especially during pregnancy. We usually treat only based on the titre in these cases, so it is important to get the titre.

If you are in the U.S., the health department will advise your provider on when to treat. You may also be checked for other conditions that might be affecting the lab results, but again, that will depend on the titres.
