Fixed (ie non weight-based) doses in adults are historically based on a 70 kg patient. Specific disease states or individual patients may warrant dosages that differ from the above recommendations. Since product-specific criteria for dose adjustment based on creatinine clearance exist, consult product information regarding specific recommendations for dosage adjustment based on estimated creatinine clearance.
