What Zofran Zydis wafers are used for

Zofran Zydis wafers belong to a group of medicines called antiemetics.

Zofran Zydis wafers work by helping to stop the nausea (sick feeling) and vomiting which can occur after certain treatments. ‘Wafer’ used in the product name, is the word used for the special type of tablet which dissolves in a few seconds when placed on the tongue. It is easier to swallow than ordinary tablets.

Zofran Zydis wafers should only be used to treat the nausea and vomiting for which they have been prescribed.

Your doctor may have prescribed Zofran Zydis wafers for another reason.

Ask your doctor if you have any questions about why Zofran Zydis wafers have been prescribed for you.

Zofran Zydis wafers are not addictive.
