- Drug-Herb Interactions.
- Anesthesia, General - Beneficial or supportive interaction with professional management, prevention or reduction of drug adverse effect; Zingiber reduces post-operative nausea and vomiting (PONV) caused by anesthetics. Possible alternative to pharmaceuticals in moderate PONV. Insufficient activity for emetic rescue in acute cases. Consider pretreatment in elective surgery patients.
- Antiplatelet Agents - Potential or theoretical adverse interaction of uncertain severity; This is based on Zingiber's "NSAID-like" activity (clinical occurrence and significance not established, increase risk of bleed negligible). Professional monitoring advised but preferably avoid.
- Cisplatin and Emetogenic Antineoplastic Chemotherapies - Beneficial or supportive interaction with professional management, prevention or reduction of drug adverse effect; Zingiber reduces acute nausea and vomiting associated with these drugs. Consider pretreatment and post-treatment (up to 24 hours) for nausea.
- Nonsteroidal Anti-inflammatory Drugs (NSAIDs) and Analgesic Antiarthritics - Beneficial or supportive interaction not requiring professional management, prevention or reduction of drug adverse effects; Zingiber given as an adjuvant helps to increase symptom relief and reduces side effects of drug allowing for lower doses.
- Phenprocoumon and Related Oral Vitamin K Antagonist Anticoagulants - Potential or theoretical adverse interaction of uncertain severity; Zingiber has a theoretical additive effect on hemostasis (one case report, conflict with clinical data, suggests risk generally overstated). Monitor INR.
