Light is simply a wave with a specific wavelength or a mixture of wavelengths; it has no color in and of itself. An object that is emitting or reflecting light to our eye appears to have a specific color as the result of the eye-brain response to the wavelength.
There is limited experience in the use of Zofran in the prevention and treatment of post-operative nausea and vomiting in the elderly, however Zofran is well tolerated in patients over 65 years receiving chemotherapy.
There are three, recent large studies that provide the best information we have on the safety of Zofran use during pregnancy. The first study was important in showing no complications in pregnancy from Zofran, but the question of birth defects was not quite answered because half of the patients started Zofran after 10 weeks gestation, which is after the critical time for organ development in the embryo.
