You may experience reduced absorption of nafcillin in the presence of food. The effectiveness of the antibiotic may be reduced. Nafcillin should be administered one hour before or two hours after meals. This will make it easier for your body to absorb the medication.

nafcillin - sodium/potassium

Each gram of parenteral nafcillin sodium contains approximately 67 mg (2.9 mEq) of sodium and is buffered with 40 mg of sodium citrate. Each 250 mg capsule of nafcillin sodium contains approximately 17 mg (0.7 mEq) of sodium buffered with calcium carbonate. The sodium content should be considered in patients with conditions that may require sodium restriction, such as congestive heart failure, hypertension, and fluid retention. In addition, hypokalemia has been reported rarely during therapy with the penicillinase-resistant penicillins, which may be particularly important to bear in mind when treating patients with low potassium reserves or fluid and electrolyte imbalance. Clinical monitoring of electrolytes is recommended if these agents are used for prolonged periods.
