Introduction
If menstrual flow suddenly increases or decreases after applying the Sanfu贴 (herbal patches) during menstruation, accompanied by significant abdominal pain, dizziness, or other discomforts, it may indicate that the medication's stimulation has affected the circulation of qi and blood; in such cases, the patch application should be discontinued. However, if menstrual flow and cycle remain normal during menstruation, with no abdominal discomfort or skin abnormalities after applying the Sanfu贴, and the herbal ingredients used are mild and do not contain blood-activating components, discontinuation may not be necessary.

Generally, if there is an abnormal menstrual flow or abdominal discomfort after applying the Sanfu patch during menstruation, the application should be paused. However, if the menstrual cycle remains stable and there is no discomfort after applying the patch, it may not be necessary to stop using it. Detailed analysis is as follows:

If after applying the Sanfu patch during menstruation, the menstrual flow suddenly increases or decreases, accompanied by significant abdominal pain, dizziness, or other discomforts, it might indicate that the medication's irritation is affecting the circulation of blood and qi. In such cases, the patch application should be paused.

If the menstrual flow and cycle remain normal during menstruation, and there is no abdominal discomfort or skin abnormalities after applying the Sanfu patch, and the medicinal ingredients used are mild and do not contain blood-activating components, and the body tolerates the patch application well, then it may not be necessary to discontinue the treatment.

During the period of applying the Sanfu patch while menstruating, pay attention to menstrual flow and physical sensations. Before applying the patch, inform the physician about your menstrual status. If any abnormal reactions occur, do not persist; remove the patch promptly and consult a healthcare professional to ensure safety.
