Compliance with prenatal vitamins. Patients with morning sickness sometimes find it difficult.

Abstract

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.
