Some MEDICINES MAY INTERACT with sinecatechins. Because little, if any, of sinecatechins is absorbed into the blood, the risk of it interacting with another medicine is low.

How to use sinecatechins:

Use sinecatechins as directed by your doctor. Check the label on the medicine for exact dosing instructions.

  • An extra patient leaflet is available with sinecatechins. Talk to your pharmacist if you have questions about this information.
  • Wash your hands before and immediately after using sinecatechins.
  • Gently apply a small amount of sinecatechins to each wart using the tips of your fingers. Completely cover each wart being treated, leaving a thin film of medicine on the wart.
  • Be careful not to get sinecatechins in the vagina or the anus.
  • Do not apply sinecatechins to open sores or broken skin.
  • Do not wash sinecatechins off before you apply your next dose. If you will be taking a shower or bath, apply sinecatechins afterwards.
  • Do not bandage, cover, or wrap the treated area; however, you may wear loose-fitting undergarments.
  • Uncircumcised men with warts under the foreskin should pull back the foreskin and clean the area every day.
  • Use sinecatechins on a regular schedule to get the most benefit from it. Using sinecatechins at the same times each day will help you remember to use it.
