Answer: First of all, every pregnant or nursing mother and her doctor must carefully weigh the benefits to the woman against the risks to her fetus or infant when using any medication. Always inform your doctor if you are pregnant, planning a pregnancy or breastfeeding before using any medicine. That being said, nasal steroids are generally well tolerated during pregnancy and by nursing mothers. Benadryl is probably the safest antihistamine to use because it's been around the longest, although it can cause drowsiness. Many of the newer antihistamines have either not been tested, or they have been found to be present in breast milk. Great caution should be used with all of these medications and certainly not before a thorough consultation with your doctor.
SPL documents contain both the content of labeling (all text, tables and figures) for a product along with additional machine readable information (including drug listing data elements and clinical data elements). Drug listing data elements include coded information about the product (including product and generic names, ingredients, ingredient strengths, dosage forms, routes of administration, appearance, DEA schedule) and the packaging (package quantity and type). Clinical data elements include coded information about the clinical use of the product (including indications and use, contraindications, drug interactions, warning and precautions and use in special populations).
Saline was believed to have originated during the Indian Blue cholera pandemic that swept across Europe in 1831. William Brooke O'Shaughnessy , a recent graduate of Edinburgh Medical School , proposed in an article to medical journal The Lancet to inject cholera patients with highly oxygenated salts to treat the "universal stagnation of the venous system and rapid cessation of arterialisation of the blood" seen in severely dehydrated cholera patients.  He found his treatment harmless in dogs, and his proposal was soon adopted by the physician Thomas Latta in treating cholera patients to beneficial effect. In the following decades, variations and alternatives to Latta's solution were tested and used in treating cholera patients. These solutions contained a range of concentrations of sodium, chloride, potassium, carbonate, phosphate, and hydroxide. The breakthrough in achieving physiological concentrations was accomplished by Sydney Ringer in the early 1880s,  when he determined the optimal salt concentrations to maintain the contractility of frog heart muscle tissue. Normal saline is considered a descendant of the pre-Ringer solutions, as Ringer's findings were not adopted and widely used until decades later. The term "normal saline" itself appears to have little historical basis, except for studies done in 1882–83 by Dutch physiologist Hartog Jacob Hamburger ; these in vitro studies of red cell lysis suggested incorrectly that % was the concentration of salt in human blood (rather than %, the true concentration).
