RT Journal Article SR Electronic T1 Compliance with prenatal vitamins. Patients with morning sickness sometimes find it difficult. JF Canadian Family Physician JO Can Fam Physician FD The College of Family Physicians of Canada SP 1392 OP 1393 VO 52 IS 11 A1 Koren, Gideon A1 Pairaideau, Nicholas YR 2006 UL http://www.cfp.ca/content/52/11/1392.abstract AB QUESTION: Many pregnant patients cannot tolerate multivitamins because of morning sickness. Is it the tablet size or the iron content that causes the problems, and what can be done? ANSWER: Recent Motherisk studies have shown both tablet size and high iron content to be associated with lower compliance among women with morning sickness. It does appear that tablet size is more likely to affect compliance. Some new multivitamin tablets are smaller, and some have less iron content.
