Since I use this medication to BREATHE....I was upset to find the inhaler did not work properly! Duh!! The nebulizer/inhaler stopped spraying with 135 sprays still indicated inside the unit. I'm not sure when it actually quit spraying. It is clearly faulty! Just as I expected....Teva Pharmaceuticals has NOT notified me of my complaint/issue! I file a complaint over a week ago. Since they have their money....their interest in me as a customer is zero. "So what if he can't breathe because our medication failed....we got our money so TOUGH!!" Perhaps more attention could be paid to quality control instead of the "bottom line"! User's recommendation: Ask your physician to perscribe medication from another manufacture...
