Drug Precautions ::

 Precautions

Pregnancy: Category B. Lactation: Undetermined. Children: Safety and efficacy in children < 2 yr not established. ECG Changes: Can cause ECG interval change (PR, QTc, JT) prolongation and QRS widening) which could cause cardiovascular consequences, including heart block and arrhythmias. These changes are related in magnitude and frequency to the active metabolite. Conditions predisposing to prolongation of cardiac conduction intervals (eg, electrolyte abnormalities, class 1A antiarrhythmias, etc): Use with caution.

PATIENT CARE CONSIDERATIONS


Drug Side Effects ::

 Adverse Reactions

CV: Tachycardia; bradycardia; flushing; hypertension; hypotension. CNS: Headache; vertigo; dizziness agitation; drowsiness; sleep disorder; depersonalization. DERM: Rash; itching; sweating. GI: Abdominal pain; constipation; diarrhea; dyspepsia; anorexia; taste perversion; abnormal liver function. GU: Oliguria; urinary retention. OTHER: Fever; fatigue; pain; chills; shivering.

Drug Mode of Action ::  

 Action Selective serotonin (5–HT3) receptor antagonist that inhibits serotonin receptors in the GI tract and chemoreceptor zone.

Drug Interactions ::

 Interactions

Drugs which prolong the QTc interval (eg, quinidine, etc): Additive effects on conduction. Atenolol: Increased serum levels of active metabolite (IV only). Cimetidine: Increased serum levels of active metabolite. Rifampin: Decreased serum levels of active metabolite.

Drug Assesment ::

 Assessment/Interventions

  • Obtain patient history, including drug history and any known allergies. Note risk factors which can cause ECG interval changes.
  • Assess patient for nausea, vomiting and side effects.
  • Monitor I & O carefully.
  • Be prepared to give additional IV fluids to patient who is vomiting but do not overhydrate.
OVERDOSAGE: SIGNS & SYMPTOMS
  Hypotension, dizziness

Drug Storage/Management ::

 Administration/Storage

  • Administer oral dose without regard to food.
  • Dolasetron injection may be mixed with apple or apple-grape juice for oral administration in pediatric patients. Use within 2 hrs of dilution.
  • Dolasetron injection can be infused IV as rapidly as 100 mg/30 seconds or diluted in 50 ml of a compatible IV solution and infused over a period of up to 15 min.

  • Store tablets and undiluted injection at room temperature protected from light.

Drug Notes ::

 Patient/Family Education

  • Advise patient that headache is common side effect.
  • Advise patient that medication will greatly reduce likelihood of nausea and vomiting but that these are still possible.
