 Interactions

HMG-CoA reductase inhibitors (eg, lovastatin):

Increased risk of myopathy and rhabdomyolysis.

Increased tacrolimus plasma levels with increased risk of toxicity.

Warfarin:

The anticoagulant effect may be increased, increasing the risk of hemorrhage.

 

 Lab Test Interferences None well documented.

 

 Adverse Reactions

CARDIOVASCULAR: Palpitations; chest pain. CNS: Dizziness; headache; vertigo; somnolence; fatigue. DERMATOLOGIC: Rash; photosensitivity.

 Precautions

Pregnancy: Category B. Lactation: Undetermined. Cardiac effects: Serious cardiovascular events have occurred with other macrolide antibiotics, especially when given concomitantly with certain antihistamines (eg, terfenadine).

Pseudomembranous colitis: May be factor in patients who develop diarrhea.

PATIENT CARE CONSIDERATIONS


 

 Administration/Storage

Oral suspension/Tablets

  • Administer 1 hr before or 2 hr after meal.
  • Tablets can be taken without regard to meals.
  • Time doses evenly throughout day for optimal blood levels.

Adults and children 16 yr and older: PO 500 mg as a single dose on the first day followed by 250 mg once daily for 4 days.

 

 Interactions

HMG-CoA reductase inhibitors (eg, lovastatin):

Increased risk of myopathy and rhabdomyolysis.

Tacrolimus:

Increased tacrolimus plasma levels with increased risk of toxicity.

Warfarin:

The anticoagulant effect may be increased, increasing the risk of hemorrhage.

 

 Lab Test Interferences None well documented.

 

 Adverse Reactions

CARDIOVASCULAR: Palpitations; chest pain. CNS: Dizziness; headache; vertigo; somnolence; fatigue. DERMATOLOGIC: Rash; photosensitivity. GI: Diarrhea; nausea; vomiting; abdominal pain; dyspepsia; flatulence; melena. GU: Vaginitis; monilia; nephritis. HEPATIC: Cholestatic jaundice. OTHER: Angioedema; anaphylaxis.

 

 Precautions

Pregnancy: Category B. Lactation: Undetermined. Cardiac effects: Serious cardiovascular events have occurred with other macrolide antibiotics, especially when given concomitantly with certain antihistamines (eg, terfenadine). Gonorrhea/Syphilis: Ineffective for treatment of these infections. Hepatic/Renal function impairment: Use cautiously. Pneumonia: Only effective for mild community-acquired pneumonia. Pseudomembranous colitis: May be factor in patients who develop diarrhea.
