For Kidney Infections "I started taking this antibiotic about 12 hours ago before bed. Though the UTI symptoms subsided, they were replaced with a spell of horrible side effects from the medication. I woke up every couple of hours to drink water because I felt dehydrated, then I would quickly throw the water up. I had frequent sleep paralysis nightmares and was beginning to hallucinate, experience anxiety, and have a sore throat. When I cough, it gives me a splitting headache. The absolute delirium I feel mixed with the blurry vision I was experiencing, joint pain, and confusion on top of everything else absolutely freaked me out. So much so that I was even scared to lay down alone in my room. I walked very hunched back to my computer due to back pain and looked up the medication to find that many have experienced all of these symptoms as well. I am really agitated that I have to take this medication for 6 more days. I don't think I will finish it."

For Bacterial Infection "Took this for a bad infection of a tooth that had gone into soft tissue. Within 2 hours of the first dose, I felt like I was dying in pain from the worst headache of my life... That says a lot for me because I suffer from migraines since the age of 12. I'm 29 and not the healthiest, so I don't know if that plays a part in how my body handles it. I am going to finish the antibiotic because I've heard it works amazingly. Hope this helps. Dosage 500 mg/4x a day for 10 days."

For Bacterial Infection "Second time I have taken this. First time was 4 years ago for cellulitis, 500 mg 4 times a day for 10 days, and it worked, but I was in bed most of the time post-surgery. This week, I was on it for a possible bacterial infection of neck up. 500 mg 3 times a day for 5 days. Very tired the entire time, legs hurt to where it was hard to walk sometimes, my neuropathy got bad in my feet for one morning only. I had a little numbness near my mouth for a short time twice, had some whopper headaches, I dreamed heavily, which I don’t do. My back molar is bothering me, and I called my dentist, and they said this should clear that too. It has not. Despite these side effects, I would take it again. So, despite my side effects, I would take it again. Calling the dentist Monday!"

For Bacterial Infection "Because of my weight, I was prescribed 500 mg of this antibiotic. But that was way too much! Headaches, intestinal issues, etc. Thankfully, I feel better now, but definitely be careful of dosage."
