Advice on administration via enteral tube
Current resources suggest that it is likely to be safe to administer the dispersible tablets via enteral feeding tubes. Dissolve the tablet in the barrel of an enteral syringe. Stop the enteral feed before administration. Flush the feeding tube with water before and after administration of the medication. No break in feeding is required after the medication has been administered.
Available as other formulations?
Intravenous infusion (powder for reconstitution), cream, eye ointment
Note
Current resources suggest that the suspension preparation is extremely viscous and no specific data on enteral tube administration are available for this preparation. The suspension contains sorbital. Aciclovir is absorbed in the upper gastrointestinal tract, therefore there may be a risk of reduced absorption when the drug is given through an enteral feeding tube terminating in the jejunum. It is important to monitor the patient for clinical effect.
