My sister Laureen Lawlor-Smith has a summary of Raynauds of the nipple(including a case study written by a mother) in the next issue of Breastfeeding Review(Journal of Nursing Mothers Assn. of Aust.) We have also written an article on case studies of 5 women with nipple vasospasm. It has been submitted to a medical journal for publication.......We are waiting to hear fron them...... We have found Nifedipine useful in the dose of 5-10mg. 2-3x per day. We use the medium acting tablets(not capsules which are used for angina) Nifedipine is highly protein bound and insignificant amounts get into breastmilk.Most women tolerate it well although we have needed to change a few to long acting Nifedipine(30mg.) which is better tolerated by some women.Some of the mothers have been able to stop the drug when the weather got warmer and others have needed to continue it for the whole time they were breasfeeding.Carolyn Lawlor-Smith DR/LC South Australia
