Does keflex clear sinus infection?

Cephalexin. Not best choice for sinusitis, but it is is acute, the causative organism sensitive to first generation cephalosporins, and you absorb it adequately it may work well. Under the best of circumstances Cephalexin (keflex) yields low serum concentrations and entry into the sinuses in therapeutic concentrations may be problematic. Amoxicillin, trimethoprim-sulfa might also be effective.

Saturday woke w/gunk on eye. Cleared when blinked. No pink or itch. Sinus infection. Rx'd Tobramycin 2 drops 3x's day for 7 days. Keflex Enuf drops?

Sounds viral. Over all it sounds like a viral infection with both sinus and eyes involved. Bacterial eye infection/conjunctivitis usually have continuous pus like discharge all day. Gunk on eye in the morning is not specific for bacterial infection. Viral infection and allergies can also cause gunk on eye in the morning. Over use of antibiotic to treat viral infection can lead to resistant bacteria later on. Read more...

Been taking keflex 500mg 4 times daily for sinus infection. Have no symptoms other than low grade fever. How or when will I know if its going to work?

Depends. Keflex is a cephalosporin type antibiotic, which is rather broad spectrum. It can be bacteriostatic (knocks them down) or bacteriocidal (kills them-bacteria). I do not know how long you have been taking it, but a full course of 7 days needs to be taken. If not better by then, a culture and sensitivity test should be done to find the appropriate drug for a full cure. Read more...
See below. Sinusitis is characterized by nasal congestion, purulent nasal discharge, headache and facial pain over the sinuses in the frontal and maxillary areas. Low grade fever alone would not indicate sinusitis. Sinusitis is usually self limited and does not require antibiotics unless severe or prolonged. Keflex is not the best drug for sinusitis. Ceftin, (cefuroxime) vantin or Augmentin would be better choices. Read more...

Is keflex good for sinus infection and upper respiratory infection?

Only. If it is a bacterial infection. Most upper respiratory infections however, are viral and many people mistake a viral rhinnitis for sinusitis and take unnecessary antibiotics.
