What are the side effects of Sanfu patches?

Sanfu patches exert the therapeutic principle of “treating winter diseases in summer” and also serve preventive and health-promoting functions. They are highly effective in managing chronic bronchitis, cough, low back pain, cervical spondylosis, lumbar spine disorders, gynecological conditions, menstrual irregularities, dysmenorrhea, and infertility.

What Are the Side Effects of Sanfu Patches?

Sanfu patches themselves do not have prominent side effects. However, some individuals may experience localized itching, warmth, or mild pain after application; a small number may develop blisters at the application site. Noticeable skin pigmentation following application is a normal physiological response. If large or severe blisters occur, scratching must be strictly avoided—prompt consultation with a dermatologist is recommended. Individuals with known allergies may exhibit symptoms such as erythema, swelling, or pruritus.

Improper use of Sanfu patches may lead to localized skin erythema and edema, along with pruritus. Some individuals may also experience palpitations, which can further trigger allergic reactions.

Sanfu patches are contraindicated for individuals with severe eczema, contact dermatitis, or other active dermatoses; those with compromised or damaged skin; or those with known hypersensitivity to any of the patch’s ingredients. Although Sanfu patches demonstrate excellent efficacy—particularly for respiratory and musculoskeletal disorders—not everyone is suitable for their use. Caution is advised for patients with malignant tumors, infectious diseases, diabetes mellitus, pregnant women, individuals with implanted cardiac pacemakers, and those with known skin allergies.

        Always follow your physician’s instructions when using Sanfu patches. Maintain good personal hygiene during treatment, and change undergarments regularly.We hope this information is helpful to you!
