There are Some Drug Connection With Tolvasca Tablet (Tolvaptan)

Tolvaptan can interact with other medications, altering their effectiveness or increasing the risk of side effects. It is important to inform your healthcare provider about all the medications, including prescription, over-the-counter drugs, and herbal supplements, that you are currently taking. Here are some notable drug interactions:

CYP3A4 Inhibitors: Tolvaptan/Samsca is metabolized by the CYP3A4 enzyme. Co-administration of strong CYP3A4 inhibitors, such as ketoconazole, clarithromycin, or ritonavir, may increase Tolvaptan blood levels. Your healthcare provider may adjust the Tolvaptan dosage or monitor you closely for potential adverse effects.

CYP3A4 Inducers: Concurrent use of strong CYP3A4 inducers, such as rifampin, phenytoin, or St. John's wort, may reduce Tolvaptan blood levels. Your healthcare provider may consider increasing the Tolvaptan dosage or opting for alternative medications.

Diuretics: Tolvaptan is a diuretic itself, and combining it with other diuretics may result in excessive fluid loss and dehydration. Your healthcare provider will carefully monitor your fluid balance if Tolvaptan is co-administered with other diuretic medications.

Lithium: Tolvaptan may increase lithium blood levels, which can lead to lithium toxicity. If you are taking lithium, your healthcare provider may need to adjust your lithium dosage and monitor your lithium blood levels closely.

Other Medications: Tolvaptan may interact with medications that affect liver enzymes, electrolyte levels, or QT interval. It is crucial to disclose all your medications to your healthcare provider to prevent potential drug interactions.
