Yes, this is a safe amount. I've seen people who received 4000 mg in a 24-hour period. You're a smart cookie though. Always question. The Pharmacists who fill the prescriptions also know what the normal dosage is in medications. So, if a Doctor writes a prescription where there is an error, the Pharmacists usually catch it. Those kinds of errors usually don't happen.

Juli, Keflex is a safe antibiotic.  They give a higher dosage to knock it out sooner.  Take it with food, because, if I'm not mistaken, that stuff tastes horrible if it repeats on you.  Good luck.  Bobbie

Yes, that is a safe amount...I've been on it 4 times a day at one point and was just fine, prescribed by the doctor at that much.
