Is there a risk of going into preterm labor because of lovenox, heparin or low dose aspirin? I'm 22 weeks, feeling braxton hicks contractions on a daily basis and have history of severe anxiety which is being managed without medication and I'm concerned about preterm labor.

What can I do next?

My sister took lavanox her whole pregnancy then switched to heparin. She delievered right on schedule. Why are you concerned with preterm labor? Just because of the braxton hicks and you are wondering if they are related to the drugs? Are you saying that you have anxiety to explain that you might be just worrying about it due to the anxiety issues? I wouldn't worry if that is the case. If there is something else going on, you need to talk to your doctor. You can always call a pharmacist and ask if this is a risk associated with these drugs.

One thing to keep in mind- to my understanding you CAN NOT, absolutely can not, stop taking blood thinners once you are on them while pregnant. The risk of having a blood clot increases immensely if you are on them and get off. Are you currently taking them, or are you trying to decide whether to or not? If you are trying to decide, you need to have a conversation with your doctor about the risks of taking them, and the risks of not. Because if they are prescribing them for you there must be a very good reason to think you need them. They are not prescribed lightly. Good luck! I know this is a scary thing to deal with.

talk to your doctor or midwife before taking any medications.

You many want to consider some non-medical options too, such as accupuncture, massage and chiropractor to help ease your anxiety. If you don't have a midwife, you may try contacting one -- they often have a lot of non-medical and homeopathic suggestions that can help in many common pregnancy ailments.

No matter what you do, contact your doc/midwife before you start it -- just so they can go over the risks/benefits of it.

Good luck!

i dont know if theres a risk of preterm labor but i wouldnt be using heparin being it is a clotting agent. that just seems dangerous.

hi A.,

I was on lovenox and heparin during my pregnancies due to additional chromosomes which makes me more likely to get blood clots. (I'm not sure if you are on them for the same reason.) They did NOT cause premature labor for me. One of my kids was born 3 days late and the other 4 days late after being induced. Just make sure you follow the doctors orders, switching at 36 weeks to heparin due to it's shorter half life, and then don't take it again once you feel as though you are really in labor.
Write me back if you have any other ques's.
good luck...

To my knowledge, there is no risk of pre-term labor with any of these medications. However, I'm not sure what exactly the risks are related to pregnancy. As I'm sure you know if you're taking any of these medications, they are all blood thinners which can have dangerous side effects, but I'm sure your doctors have weighed the pros and cons of the medications with you. I know Asprin is not recommended during pregnancy. I would definitely talk to your doctor about the risks and side effects of the medications.
