What does it mean by "uncertain" in the instructions for external use?

Being marked with "Unclear adverse reactions" does not mean there is a problem with the drug. The practice of marking "not yet clear" on drugs with the national drug approval is permitted by the state. The statement "not yet clear" sounds a bit scary, but it is actually because when these breeds were observed in clinical studies, there were no adverse events in the observed groups. Such labeling does not mean that there is a problem with the medicine, nor does it mean that these medicines will not have adverse reactions in the future. Due to individual differences between patients, special attention is required when taking medicines. The most important thing is to take medicines under the guidance of a doctor and not to take medicines blindly.
