Tegoyes (Tegafur) is for external use only and should not be taken orally
Based on the FDA drug label information, Tegoyes 20 mg tablets are NOT intended for oral administration 1. The product labeling explicitly states this is "for external use only" and warns to "avoid contact with eyes and mucous membranes" 1. The warnings clearly indicate this formulation should not be used on wounds or damaged skin, and specifically advises not to use in children under 12 years old without consulting a doctor 1.
Critical Safety Issue
You appear to have a product labeled as "Tegoyes" that is formulated for topical/external use, not oral chemotherapy. This is a completely different formulation from the oral tegafur chemotherapy agents discussed in cancer treatment literature.
If You Need Oral Tegafur Dosing for Cancer Treatment
If you are actually seeking dosing information for oral tegafur chemotherapy (not the Tegoyes topical product), the research literature provides the following guidance:
Standard Oral Tegafur Dosing for Cancer:
- Recommended dose: 1,000 mg/m²/day (1.0 g/m²/day) orally, divided into 2-3 doses 2
- Typical range: 600-1,200 mg/day total dose 3, 4, 5
- Duration: Usually given for 14-21 days in cycles with rest periods 2, 6
For a 20 mg Tablet Formulation:
If you had legitimate 20 mg oral tegafur tablets, a typical adult dose would require 30-60 tablets per day (600-1,200 mg total daily dose), which should immediately signal that something is wrong with your current product.
Do not administer the Tegoyes product you have orally. Contact your pharmacist or prescriber immediately to clarify the correct medication.
