Antifungals, Azole (Systemic)

Precautions While Using This Medicine

It is important that your doctor check your progress at regular visits. This will allow your doctor to check for any unwanted effects.

If your symptoms do not improve within a few weeks (or months for some infections), or if they become worse, check with your doctor.

These medicines should not be taken with astemizole (e.g., Hismanal), cisapride (e.g., Propulsid),dofetilide (e.g., Tikosyn) or terfenadine (e.g., Seldane) . Doing so may increase the risk of serious side effects affecting the heart.

Liver problems may be more likely to occur if you drink alcoholic beverages while you are taking ketoconazole. Alcoholic beverages may also cause stomach pain, nausea, vomiting, headache, or flushing or redness of the face. Other alcohol-containing preparations (for example, elixirs, cough syrups, tonics) may also cause problems. These problems may occur for at least a day after you stop taking ketoconazole. Therefore, you should not drink alcoholic beverages or use alcohol-containing preparations while you are taking this medicine and for at least a day after you stop taking it .

If you are taking antacids, cimetidine (e.g., Tagamet), famotidine (e.g., Pepcid), nizatidine (e.g., Axid), omeprazole (e.g., Prilosec), or ranitidine (e.g., Zantac) while you are taking itraconazole or ketoconazole, take the other medicine at least 2 hours after you take itraconazole or ketoconazole . If you take these medicines at the same time that you take itraconazole or ketoconazole, they will keep your antifungal medicine from working properly.

Ketoconazole may cause your eyes to become more sensitive to light than they are normally. Wearing sunglasses and avoiding too much exposure to bright light may help lessen the discomfort.
