Severe Side Effects with Avelox 400 mg – Experiencing Blood Discharge and Breathing Issues

I was prescribed Avelox 400 mg along with Parol and Vitamin C in December for a lung infection. After following the doctor's instructions, taking my stomach protector on an empty stomach and the medication two hours after meals, I had a terrifying reaction to Avelox. I experienced shortness of breath, shock, loss of consciousness, and severe shaking. I had to rush to the ER, feeling as though I was on the brink of death. On the third day of taking the medication, I noticed blood in my discharge. I checked Bayer’s website, but Avelox wasn’t even listed. This has left me deeply worried, and I’m unable to get any feedback or answers. Is this drug safe? What is causing the blood discharge? I need urgent clarification.
