Zokinvy should be taken twice a day with food at a recommended dosage based on body surface area

Zokinvy offers flexible dosing for your patients.1

The recommended dosage of Zokinvy is based on body surface area (BSA). For convenience and flexibility, Zokinvy is available in both 50 mg and 75 mg hard capsules.1

Dose adjustment for patients with persistent vomiting and/or diarrhoea

  • For patients who have increased their dosage to 150 mg/m2 twice daily and are experiencing repeated episodes of vomiting and/or diarrhoea resulting in dehydration or weight loss, the dose can be reduced to the starting dosage of 115 mg/m2 twice daily1
  • All daily doses should be rounded to the nearest 25 mg increment and divided into 2 equal, or near equal, doses (see Table 1)1

How to take Zokinvy
