I'm looking for information on which medications are safe to take during pregnancy and during breastfeeding. I used www.motherisk.org when I was pregnant. But now that I am breastfeeding, I would like to be able to look up medications to see what the possible effects/risks might be for my baby. Does anyone have a good resource for this information?

To summarize:

During pregnancy, the best online resource for safe medications seems to be Motherisk.

During breastfeeding, the best online resource for information on medications seems to be the Drugs and Lactation Database (LactMed).

And of course, pregnant and breastfeeding women should always consult their doctors or pharmacists for advice on what is safe to take.

The leading resource for what drugs and medications are safe in pregnancy is Motherisk which is operated out of Sick Kids in Toronto.

Great site, I wish I had known about it when I was pregnant. If I could add my 2 cents to your response, I would use this as a starting point and discuss with my doc/OB/midwife, who may have further advice based on my personal situation.

Whenever I had a question like that, I would call my doctor's office or go ask a pharmacist.

Yeah, that's generally going to be the safest thing to do.

Unfortunately, my pharmacist don't seem sure about things that are safe for breastfeeding. I got a prescription yesterday and asked my pharmacist if it was safe and he said, "Well you have to take it so it doesn't matter." I wasn't satisfied with that response.

I'd find a new pharmacist. The ones I talk to are usually pretty sure. And when I'm at the doctor's office, as soon as I hear I'm going to be getting a prescription, I ask about it then. My general physician has a reference on his PDA, so if he doesn't know the answer off the top of his head, he looks it up right there.

Agreed with @mkcoehoorn - I'd be looking for a new pharmacist. Ours is great and always happy to answer questions. A response like "you have to take it" is especially concerning - first off, you need to know whether to stop breastfeeding, and second, there are very few meds that are the only option for a condition.

The CTIS Pregnancy Risk Information Line" has a list of common drugs and safety while pregnant and breastfeeding. They seem to focus more on pregnancy than breastfeeding but if you scroll toward the end of each handout there is some information on breastfeeding.

The National Institutes of Health provides a database called LactMed. Our doctors used it pretty heavily with my wife's medications when she was breastfeeding in the NICU.

This looks like a great site! Thanks for sharing.

The American Pregnancy Association has a list called Is It Safe? It doesn't address breastfeeding, however.

As Krista mentioned in her comment on dreamerisme's answer, use these lists for research, and followup with your doctor to discuss the entirety of your food, supplement, and medicine intake.
