Hi. Zanaflex is short acting medicine and dosed very 8 hours. Manufacturer has no studies human milk excretion of this drug.

My suggestion to you is that you can feed the baby 6 hours after the dose and at other times feed a formula for few days. you can also do the pump and store it.

if pump and store, please read articles about breast milk storage at Medlineplus and follow all precautions. If you accept this answer, please rate my service by clicking on the stars.

Confused about this part "My suggestion to you is that you can feed the baby 6 hours after the dose and at other times feed a formula for few days. you can also do the pump and store it." So can I feed her after six hours or are you saying formula for days??

I only took one dose. Not planning on taking more...
Expert:  Saqib replied 8 months ago.

I mean to say that if you need to feed the baby every 3-4 then you can feed formula inbetween your 6 hourly breast feeding

Customer: replied 8 months ago.
Ok so the medicine will be out of the breastmilk 6 hrs after taking it?
Expert:  Saqib replied 8 months ago.

Yes, most of it will be out

Customer: replied 8 months ago.
What are the risks.
Expert:  Saqib replied 8 months ago.

As the drug is fat soluble, it can still appear into the breast milk but the effects on the infant are not listed.

Customer: replied 8 months ago.
Ok...still not really sure what to do but thank you for Trying
Expert:  Saqib replied 8 months ago.

I will say the best solution will be to store milk and then take the dose right away and do not pump the milk for next 8 hours. And also increase the interval between drug dosing to 12 hours. That way there will be less cumulative effect and much less chance of appearing it in the milk

Hi there,
Here is a much simpler answer.
Expert:  Dr. Cooper replied 8 months ago.
You and your baby will be just fine. Feed the baby in 2-3 hours. Since you only took one single dose, there will be no harm to the baby. Baby that is born full term are not at any risk.
Expert:  Dr. Cooper replied 8 months ago.
Hope this puts your mind at ease as I can understand your concern for your 5 months olds safety.
Expert:  Dr. Cooper replied 8 months ago.
if you need to take the medication in the future, you can do it 2 different ways: no need to pump and dump or even pump and save.
1. Feed the baby and then take the medication. That will cover you and the baby for the next 4 hours.
OR
2. Take the medication and feed the baby 4-6 hours later.
Even if the medication passes in the milk, it would be an insignificant amount and baby will be perfectly safe.
Let me know if you have any further questions or concerns.

Hi there,
Following up to see if you are not "touching it out" by not taking your medicine afraid it will affect the baby adversely.
Rest assured, you and the baby will be just fine if you take the medicine as I recommended. Last thing you want is to be in pain and not able to care for your child as you can when pain free.
Please take your medicine, and continue breastfeeding.
I am here to help with any question or concern you might have.
Take care.
