All you need to do is not use the medication on the day of the test. The day before gastroscopy, you can normally take all 2-3 doses of the drug, which will not affect the result of the test.

Tribux has a short-term effect - so it is necessary to take several doses at short intervals. Therefore, maintaining an interval of about 12-14 hours between taking the last dose of the drug and the test will be sufficient.
