Allergic Reactions: Individuals with allergic constitutions are prone to allergies caused by the ingredients or adhesives in pain relief patches. Mild reactions include skin rashes and itching, while severe cases may lead to chest tightness and difficulty breathing. Clinical cases show that some patients develop widespread rashes due to untreated allergic reactions.
Risk of Physical Damage: Prolonged application or frequent removal can damage sensitive skin, causing blisters or abrasions. This is particularly concerning for infants and the elderly, as the strong adhesive power can lead to epidermal detachment and increase the risk of bacterial infection.
Chain Reaction of Infections: Improper cleaning of the application area or untreated skin damage can allow pathogenic bacteria like Staphylococcus aureus to enter, causing folliculitis or abscesses. Severe cases may require oral antibiotic treatment.
Gastrointestinal Stress Reactions: Once absorbed through the skin into the bloodstream, non-steroidal anti-inflammatory components can irritate the gastric mucosa, leading to nausea, vomiting, abdominal pain, and diarrhea. Patients with a history of gastric ulcers are more likely to experience gastrointestinal bleeding with prolonged use.
Neurological Warnings: Some potent pain relief ingredients may interfere with neurotransmitter transmission, causing dizziness, headaches, drowsiness, and fatigue. This poses safety risks for drivers and high-altitude workers if they become mentally sluggish.
Liver and Kidney Metabolic Burden: The drug ingredients are metabolized by the liver and excreted by the kidneys. Long-term use by individuals with impaired liver or kidney functions can lead to drug accumulation in the blood, harming organ function.
Pre-test for Allergies: Before first use, apply a small amount of the patch to the inner wrist and observe for 24 hours. If no abnormalities occur, proceed with regular use.
Regulate Application Duration: Do not apply the patch for more than 12 hours in a single use. Avoid using it on the same area for more than three consecutive days to prevent excessive skin irritation.
Use with Caution in Special Populations: Pregnant women, breastfeeding women, children, and patients with chronic diseases should use pain relief patches strictly under medical guidance, with careful control of dosage and duration.
