During 39 pregnancies, 33 women with a history of recurrent UTIs (and, in some instances, pyelonephritis) received postcoital prophylaxis consisting of a single oral dose of either cephalexin (250 mg) or nitrofurantoin macrocrystals (50 mg).hile 130 UTIs occurred during a mean observation period of 7 months before prophylaxis, only a single UTI occurred during pregnancy after prophylaxis; this difference was highly significant.

Change fees are in addition to the charge for the difference in fare. So, if a traveler were to purchase a domestic ticket for $300 and then want to change the dates of travel, and the price had then increased to $350, the airline would charge the fare difference of $50 plus the change fee.specially if that flight is on US Airways or United. Last week, United quietly increased the fee for changing a flight from $150 to $200 for domestic flights. Today, US Airways matched the fee increase. The change was reflected on their web site.
