Can Acyclovir tablets be crushed?
Crushing tablets is sometimes necessary — for patients who cannot swallow whole, for paediatric or elderly use, or for nasogastric tube administration. For Acyclovir (Acyclovir) at 200mg, 400mg, 800mg, whether crushing is appropriate depends on the formulation, and the answer is often "no" for modern controlled-release tablets.
When crushing is acceptable
Plain immediate-release tablet, capsule, oral suspension, topical cream of Acyclovir can usually be crushed for swallowing difficulties without affecting clinical effect. The crushed powder can be mixed with a small amount of soft food or water immediately before administration; do not store crushed tablets, as some active ingredients degrade rapidly outside the original formulation.
When crushing is not acceptable
Modified-release, enteric-coated, sublingual, buccal and certain film-coated formulations should not be crushed. Crushing destroys the controlled-release mechanism and can produce a sudden high dose of Acyclovir or expose it to gastric acid that the coating was designed to prevent. According to the prescribing information for Acyclovir, the patient leaflet states whether crushing is permitted at 200mg, 400mg, 800mg.
