It is really hard to listen to your baby cry, but do not give up breastfeeding you will have many more times to feed your baby once this is all over.
Yes give bottle to DP/DH if you can as she will rebel and just want breast from you, if she knows it is not an option she might accept bottle.
Just found this on google books in Drugs in Pregnancy and Lactation, Gerald G Briggs et.al. 1998 - there are no reports describing use of cinnarizine during human lactation the molecular weight (369) and elimination half life (3-6 hours) suggest that the drug will be excreted into breastmilk. The effects of exposure on a nursing infant are unknown.
This is because they have no research on it even on animals there is not enough data from what I have found.
From Electronic Medicines Compendium under Cinnarizine Sturgeon 15 "The safety of Stugeron in human pregnancy has not been established although studies in animals have not demonstrated teratogenic effects. As with other drugs it is not advisable to administer Stugeron in pregnancy.
There are no data on the excretion of Stugeron in human breast milk. Use of Stugeron is not recommended in nursing mothers."
If half life is 3-6 hours from book then 15mg tablet if completely metabolised and plasma levels peak after 3 hours will be 7.5 after 9 hours, 3.75 after 15, 1.875 after 21, 0.9375 after 27, 0.46875 after 33 and 0.23mg after 39 hours and even less in breastmilk as it will not have same concentration as plasma. However drug information from EMC site says half life 4-24 hours, so it could take longer to come down to that level in plasma.
