What medications should not be taken after eating crab?

Generally, it is not recommended to consume crab while taking antibiotics, anticoagulant medications, antipyretic analgesics, antidiarrheal drugs, or antihistamines, as this may affect the effectiveness of the medications. It is advised to consult a professional physician first. Detailed explanations are as follows:

1. Antibiotics: Such as amoxicillin capsules and cefixime granules. Crab contains abundant protein, which might interfere with the absorption of antibiotics when consumed together, thereby reducing drug efficacy.

2. Anticoagulant medications: Such as enteric-coated aspirin tablets and clopidogrel sulfate tablets. The vitamin K and other components in crab may affect the anticoagulant effects of these medications, potentially leading to abnormal bleeding or coagulation function.

3. Antipyretic analgesics: Such as paracetamol tablets and ibuprofen sustained-release capsules. The protein and purine substances in crab may increase gastrointestinal irritation. Taking them together with antipyretic analgesics could lead to symptoms such as indigestion and abdominal pain, and may also reduce drug effectiveness.

4. Antidiarrheal drugs: Such as montmorillonite powder and loperamide hydrochloride capsules. Crab is cold in nature and difficult to digest. Taking it together with antidiarrheal drugs may worsen gastrointestinal discomfort and exacerbate diarrhea.

5. Antihistamines: Such as loratadine tablets and cetirizine hydrochloride capsules. Crab is a type of seafood that may easily cause allergic reactions. Consuming crab while taking antihistamines might reduce drug effectiveness and potentially worsen allergic symptoms.

To ensure drug effectiveness and avoid adverse reactions, it is recommended to avoid eating crab during the course of taking the above medications. Additionally, maintaining healthy dietary habits and lifestyle practices, such as avoiding staying up late, is also advised while taking medications.
