Km. Neuzil et al., SAFETY AND PHARMACOKINETICS OF VITAMIN-A THERAPY FOR INFANTS WITH RESPIRATORY SYNCYTIAL VIRUS-INFECTIONS, Antimicrobial agents and chemotherapy, 39(5), 1995, pp. 1191-1193
Infants with respiratory syncytial virus infection have low serum vita
min A levels. We treated 21 respiratory syncytial virus-infected child
ren with 12,500 to 25,000 IU of oral vitamin A. Vitamin A levels were
normalized at 6 h, and none of the children experienced vitamin A toxi
city or exacerbation of respiratory illness. Vitamin A treatment of pr
eviously healthy respiratory syncytial virus-infected infants at these
doses is safe and well tolerated.
