What are the contraindications of Fengshi Gutong Pills?

Contraindications for Fengshi Gutong Pills generally include: pregnant women should not use, people with allergic constitutions should use with caution, those with bi syndrome due to damp-heat should avoid use, children and elderly individuals should use cautiously, and they should not be taken concurrently with certain medications. Specific details are as follows:

1. Pregnant women contraindicated: Fengshi Gutong Pills contain ingredients that promote blood circulation, remove blood stasis, unblock meridians, and relieve pain. These components may affect fetal stability and even lead to adverse pregnancy outcomes. Therefore, pregnant women must strictly avoid taking this medication to prevent harm to both mother and fetus.

2. Use with caution in individuals with allergic constitutions: Some people may be allergic to herbal ingredients in Fengshi Gutong Pills (such as Aconite species, frankincense, myrrh, etc.). Allergic individuals may experience allergic reactions such as rashes, itching, or difficulty breathing after taking the pills. Use should only occur after medical evaluation, and close monitoring of bodily responses is required during initial use.

3. Not suitable for bi syndrome due to damp-heat: Fengshi Gutong Pills tend to have warming properties and are primarily indicated for bone pain caused by wind-cold-dampness invasion. In cases of damp-heat bi syndrome (manifested as red, swollen, hot, and painful joints, bitter taste in mouth, dark yellow urine, etc.), taking this warming formula may exacerbate internal damp-heat, worsening symptoms and violating the principle of pattern differentiation in treatment.

4. Use with caution in children and elderly: Children's organs are not fully developed and their ability to metabolize drugs is weaker; elderly individuals often have reduced liver and kidney function, leading to slower drug elimination. Both groups face increased risks of adverse reactions. Dosage adjustments should be made under a doctor’s guidance—self-medication is not recommended.

5. Should not be taken with certain medications: Concurrent use of Fengshi Gutong Pills with anticoagulants, antihypertensives, hypoglycemic agents, or other specific drugs may result in drug interactions that alter efficacy or increase toxicity and side effects. For example, combining with anticoagulants may increase bleeding risk. Patients should inform their doctor of all current medications to avoid inappropriate combination therapy.

Fengshi Gutong Pills should be used strictly according to medical instructions—do not adjust dosage or prolong treatment duration without authorization. If adverse effects such as nausea, vomiting, palpitations, or limb numbness occur during treatment, discontinue use immediately and seek medical attention.
