My son started taking Keflex 500 MG for a knee injury because of a Dirt bike accident and he had a MAJOR anxiety attack, had the sweats and felt like he was going to vomet. I never in my life saw him like that and I don't ever want to see him like that again. I will never use that Antibiotic or have any of my boys use it.
