Other medicines

Look at the list of medicines given above that must not be taken while you are taking posaconazole. In addition to the medicines named above there are other medicines that carry a risk of rhythm problems that may be greater when they are taken with posaconazole. Please make sure you tell your doctor about all the medicines you are taking (prescribed or non-prescribed).

Certain medicines may increase the risk of side effects of posaconazole by increasing the amount of posaconazole in the blood.

The following medicines may decrease the effectiveness of posaconazole by decreasing the amount of posaconazole in the blood:

• rifabutin and rifampicin (used to treat certain infections). If you are already taking rifabutin, you will need a blood test and you will need to look out for some possible side effects of rifabutin.
• phenytoin, carbamazepine, phenobarbital or primidone (used to treat or prevent fits).
• efavirenz and fosamprenavir used to treat HIV infection.

Posaconazole may possibly increase the risk of side effects of some other medicines by increasing the amount of these medicines in the blood. These medicines include:

• vincristine, vinblastine and other “vinca alkaloids” (used to treat cancer)
• venetoclax (used to treat cancer)
• ciclosporin (used during or after transplant surgery)
• tacrolimus and sirolimus (used during or after transplant surgery)

• diltiazem, verapamil, nifedipine, nisoldipine or other “calcium channel blockers” (used to treat high blood pressure)
• digoxin (used to treat heart failure)
• glipizide or other “sulfonylureas” (used to treat high blood sugar)
• all-trans retinoic acid (ATRA), also called tretinoin (used to treat certain blood cancers).

If any of the above apply to you (or you are not sure), talk to your doctor or pharmacist before taking posaconazole.
