I started with a cold last week. On Wednesday (June 15, 2005) my doctor gave me some cough meds. Then I went back on Friday, still ill. He prescribed Zurtech (SPELLING?) Antibiotic? And some other breathing med that starts with a "V" I belive... and Singulair. I took it, laid down. FIVE min later, I sat up in bed. My throat had closed and I was having a hard time breathing today. My 12 year old had to call 9-11. When they came they couldn't understand what was wrong with me. My BP was like about 178/100 (That afternoon it was 122/70) and my pulse was even elevated. My lungs were totally clear. They had me sign a release of liability and then left. When I looked on the net I see that this drug CAN cause the throat to close! NO MORE OF THIS FOR ME!!!!!
