 1  Mastitis Extreme dizziness and feeling like I'm in a dream-like state now that I'm up. Bizarre dreams that I attributed to fever at first, but my fever has been down for days. I'm calling my doctor before I take another dose now that I realize all my weird symptoms the past few days are probably related to keflex! F 35 1 days

 3  upper respiratory/sinus infection I think it took care of the infection, but the side effects were ugly. Had the usual antibiotic-induced g.i. distress, which responded well to taking a probiotic and drinking kefir 2x a day. The worst was the malaise and severe depression. Wanted to quit job, quit hobbies, give up on life. Being made to feel this way while sick is MOST unfortunate. It did not go away quickly once off the drug, either. Continued enough that I felt half crazy. It is possible it interferes with absorption of my anti-depressant. Will beg for an alternative if a doctor tries to give me this again. The depression resulting from it was more toxic than the infection I had. F 58 7 days

 5  Sinus Infection I had heart pals and immediately knew I was low on magnesium. Once the doc checked...I was right. I take two 400mg of Mag a day, no sadness, or blues..no crying or meaness. No anxiety....because Mag cures all these symptoms. Keflex depletes Mag horribly....which in turn, causes hearts pals....Mag is needed for ventricle contractions. The heart pals, cause anxiety....the list goes on. Mag is a mood booster, therefore when delepted, it causes depression. Eat some nuts people....and smile, because Keflex is a awesome drug, when you know science. Love ya!! F 31 10 days

 1  Upper Respiratory 1st time I ever got this med!! I had first taken it after getting a bad chest cold for 2 days, I started feeling so sad, lost & depressed! I was very paranoid, & very just angry & mean!! It helped my congestion, but I really had the worse body feeling- pain in legs no energy very sleepy I thought it was just a bad flu, & was scared that I was getting very "dark depressed" ! I just stopped, about 2 days later I was my normal chipper self! I really thought it to be something else So about 3 days later, I felt the congestion again & thought I would take 1 b4 bed & knock it out ( I don't like taking antiobiotics for longer than needed!!) I was in a happy mood & had been energetic , took it 30 minutes b4 bed, after falling asleep I had the worse "most real nightmare & prob 1st night terror in my life!!! It was the most real dream, I was looking out from my eyes! I was being kept from my family, in a place I was scared, it was dark & evil I got a chance to leave & felt I was riding in a car, like really felt it! We stopped & I got out, I ran & the streets got Darker, like the dark was chasing me, I could feel the evil behind me ( like shadows in the dark) I turned to face it & I seen this creature, & ran again but this time I heard voices screaming run your almost safe then jump & I grabbed a rope & I swung into a group of people & woke up , I had shakes ,cold sweats & felt scared!!!

 1  Infected cryptic tonsils Extreme and debilitating dizziness, nausea, and fatigue all coupled with uncontrollable laughter on one occasion, headaches, intense chills, feelings of losing my mind Dizziness may not seem like a big deal, sleeping on the floor because I am too dizzy to stand without falling. There have been times where I was sitting and even that was too much. I've been tying my hair back, something I never do, just in case I have to run and puke. I've been taking non-optional five hour long naps or longer and then staying up all night. I have headaches all the time and get freezing cold chills very suddenly. Also, I have felt like I've been losing my mind hearing things and having absurd thoughts. I have been on this drug for four days out of the ten I am supposed to be on it and I feel like I want to kill myself. Unfortunately, I probably wouldn't be able to stand long enough to get the job done because I am so dizzy. I would recommend this drug to absolutely no one as it is one messed up trip the entire time you're on it. However, it does seem to be clearing up the infection, so there's that. But to be honest, I'd rather go without the Keflex even if I can't eat or drink because my tonsils got too big to swallow. That would be a better alternative than taking these pills. Which, by the way, smell and taste like rancid bacon. F 18 4 days

 2  facial cellulitis This drug is causing more problems and does not seem to be helping. The left side of my face remains swollen, I have no energy and life seems hopeless. I know it is the drug causing it so I HOPE it will cure my facial cellulitis, but, I would never take this again. I am thankful for locating this site. Sometimes the cure is worse than the disease! Worst antibiotic I have ever taken. F 61 3 days
