Respitory symptoms and conditions

I have been taking Singulair for at least 10 years, most of which on a daily basis. I had severe stomach pains and nausea for a period of time, went through a lot of testing and other medications all of which did not help and was at times limited to eating saltines. I also experienced anxiety attacks and depression. The depression would be on and off for periods of time. I attempted suicide several times. Only within the past 3 years, 3 years in which I was not taking my Singulair regularly (limited the Singulair to a few days at a time when I had asthma attacks or respiratory colds), was I no longer suicidal. I am not blaming these symptoms on Singulair but it is no surprise to me if it was the cause, as it was the only medication I took daily in that time period.

I've had recurring bronchitis for years and have used just about every drug, so my physician gave me someLevaquin about 2 months ago with 2 refills in case of another bout. Well, the first go around (7 days 500mg.) went fine and the bronchitis cleared up. The seconf go around, last week, was quote different. I took a pill and started to feel some relief; I took a second pill and hell broke loose. I had chest pain, numbness in my hands, a mild panic attack and trouble breathing. So I called the Pharmacist and he said STOP now!.
He then asked me if it was the first time I had tried Levaquin and I told him no. He then told me that it's not unusual for your body to produce a protein that then lives in it aftee the first shot and the, upon a second dose sees the Levaquin as a foreign body and produces these respitory dide effects.
I say this becasue he continued to tell me that had I not stopped I could have been hospitalized within a couple of days.
My point is that such an incredible drug with such wonderful potential for good can kick you in butt big time and that any side effect should be considered a red flag, stop taking it and report the effect to your physician post haste.
