Diflucan, while effective, can cause side effects. Common ones include headache, nausea, and diarrhea. These usually are mild and resolve without intervention. However, more serious reactions, though rare, require immediate medical attention. These include severe allergic reactions (rash, swelling, difficulty breathing), liver problems (jaundice, dark urine), and seizures.
Liver Function
Diflucan can affect your liver. Regular blood tests may be needed, particularly if you have pre-existing liver conditions or take other medications metabolized by the liver. Inform your doctor about all medications you are taking, including over-the-counter drugs and supplements, to prevent interactions.
Medication Interactions
Diflucan interacts with several medications. This can alter their effectiveness or increase the risk of side effects. Some notable examples include: warfarin (blood thinner), certain oral contraceptives, and some drugs used to treat heart conditions. Always discuss all medications with your doctor or pharmacist before starting Diflucan.
