Particular caution is advised when using Ketokonazol Polfarmex:
There have been reports of anaphylactic reactions (severe allergic reaction) after taking the first dose of the medicine.
Do not drink alcohol during treatment with ketoconazole. There have been reports of disulfiram-like reactions (flushing, pulsating headache, nausea, and vomiting, difficulty breathing). The symptoms resolve on their own within a few hours.
Consult your doctor, even if the above warnings refer to past situations.
Tell your doctor or pharmacist about all medicines you are currently taking or have recently taken, as well as any medicines you plan to take.
Ketoconazole inhibits the metabolism and increases the plasma concentration of astemizole, terfenadine, cisapride, cyclosporine, HMG-CoA reductase inhibitors (simvastatin and lovastatin), enhances the sedative and hypnotic effects of benzodiazepines (mainly midazolam and triazolam), and the anticoagulant effect of warfarin.
Imidazole derivative antifungal medicines enhance the effect of oral antidiabetic medicines.
It is not known whether this interaction occurs with ketoconazole.
Concomitant use of ketoconazole and medicines metabolized by the cytochrome P450 system (terfenadine, astemizole, mizolastine, quinidine, pimozide, midazolam, triazolam, cisapride) increases the risk of life-threatening heart rhythm disorders (ventricular arrhythmias, including torsade de pointes).
Particular caution is advised when taking ketoconazole with oral anticoagulants, HIV protease inhibitors (indinavir, saquinavir), oncology medicines (vinca alkaloids, busulfan, docetaxel), dihydropyridine calcium channel blockers, verapamil, cyclosporine, digoxin, buspirone, alfentanil, sildenafil, alprazolam, ebastine.
When taking ketoconazole with cyclosporine, it is recommended to monitor cyclosporine plasma concentrations and adjust the dose if necessary. When taking warfarin, it is recommended to monitor prothrombin time.
When taking ketoconazole with medicines that reduce stomach acid (e.g., antacids, proton pump inhibitors, H2 receptor antagonists), ketoconazole should be taken at least 2 hours before administration of these medicines. Patients with achlorhydria (e.g., some patients with AIDS) are advised to take ketoconazole with cola-type beverages.
In diabetic patients treated with oral antidiabetic medicines, it is recommended to periodically monitor blood glucose levels at the beginning of treatment.
Alcohol and medicines with potential hepatotoxic effects taken concomitantly with ketoconazole increase the risk of liver damage, especially in patients taking ketoconazole for a long time and in patients with a history of liver disease.
Ketoconazole increases the plasma concentration of phenytoin, and phenytoin decreases the plasma concentration of ketoconazole.
Antacids, anticholinergic medicines, H2 receptor antagonists, proton pump inhibitors, sucralfate may significantly reduce the absorption of ketoconazole.
Rifampicin and isoniazid decrease the plasma concentration of ketoconazole; concomitant administration of these medicines is not recommended.
