Be sure to remember why contraceptive pills should not get wet!

The main active ingredient of oral contraceptives is on the sugar coating

The sugar coating is most susceptible to moisture and deterioration. If the medicine is stored for too long and the air humidity is too high, the sugar coating will deliquesce; if the hands are not dried after washing or the hands are sweaty and the medicine is not taken with the medicine spoon, the water on the hands will adhere to part of the medicine sugar coating, which may cause the loss of the active ingredients of the medicine.

Partial loss may cause hormone mutations in the body due to insufficient dosage, resulting in irregular vaginal bleeding, while complete loss may lead to contraceptive failure.
