Resumo
Conivaptan is a CYP3A4 substrate and clarithromycin markedly increases its exposure. This may lead to excessive aquaresis, overly rapid sodium correction, and a risk of osmotic demyelination. Labeling contraindicates strong CYP3A4 inhibitors.
O que esta interação significa em palavras simples
Clarithromycin and Conivaptan are not normally used together. Taking them at the same time is expected to cause harm or make one of them unsafe, so a different medicine is usually chosen for one of the two.
Por que acontece
Clarithromycin inhibits CYP3A4 and reduces conivaptan clearance.
O que fazer
Do not coadminister; use an alternative antibiotic and monitor serum sodium closely during conivaptan therapy.
O que perguntar ao farmacêutico
- Is there an alternative to one of these two medicines for me?
- If both are essential, who is monitoring me and how often?
- Which symptoms mean I should stop and seek help straight away?
