Bit by Brown recluse a week ago &prescribed Keflex 2000 mg/day should i get second opinion? Why is the area now warm With Yellowish gray in the middle

Mrsa is generally treated with Bactrim or clindamycin, but again, drainage is the key. ...Read more

How long does keflex take to work?

7-10 days: Antibiotics such as Keflex can work in 7-10 days sometimes shorter- it is important to complete the course of therapy prescribed for you in order to completely eradicate the infection.
