Question
My sister-in-law just had a baby a week ago. Her doctor presribed Darviset (not sure of the spelling), for her epesiotomy. She is breastfeeding and the whole family is giving her a hard time. Is it harmful on the baby?  

Answer
Hi there,

Thanks for the question.  Was her doctor informed that she was breastfeeding when he gave her the prescription?

Darvocet is the correct spelling and here is some information that is pertinent:

Most important fact about this drug
You can build up tolerance to, and become dependent on, these drugs if you take them in higher than recommended doses over long periods of time.

How should you take this medication?
Take these drugs exactly as prescribed. Do not increase the amount you take without your doctor's approval. Do not take them for any reason other than those for which they are prescribed. Do not give them to others who may have similar symptoms.

If you miss a dose?
Take it as soon as you remember. If it is almost time for your next dose, skip the one you missed and go back to your regular schedule. Do not take 2 doses at once.

What side effects may occur?
Side effects cannot be anticipated. If any develop or change in intensity, inform your doctor as soon as possible. Only your doctor can determine if it is safe for you to continue taking one of these medications.
- More common side effects may include:
 Drowsiness, dizziness, nausea, sedation, vomiting
If these side effects occur, it may help if you lie down after taking the medication.

Special information if you are breastfeeding
Darvocet-N does appear in breast milk. However, no adverse effects have been found in nursing infants.

Well done to your sister-in-law for deciding to breastfeed, regardless of other people.  She just needs to make sure that she doses herself strictly to doctors orders to avoid later problems, especially dependency.

Please let me know if there is anything else that I can assist with.
