Pharmacist tips for Fluconazole (Diflucan)

pharmacist
  • You can take fluconazole (Diflucan) with or without food. But nausea and stomach pain are common, so taking it with food can help ease or prevent these from happening.

    • Make sure to finish your entire treatment course. Don't stop taking fluconazole (Diflucan) early unless your prescriber specifically told you to do so. Stopping fluconazole (Diflucan) too soon can cause your infection to come back and become more difficult to treat.

      • If you're taking fluconazole (Diflucan) to treat a vaginal yeast infection, avoid having sex until your infection is completely better. Having sex before your infection is cleared up can be painful and make symptoms, like burning and itching, worse. There's also a risk to pass the infection to your partner.

        • Although rare, fluconazole (Diflucan) can cause dizziness and seizures. Be careful while driving or operating machinery, especially if you have a history of seizures or other nervous system problems.

          • Contact your prescriber if you develop other symptoms of an illness or if your symptoms become worse. This could be a sign that you're infected with a virus or bacteria instead of a fungus. If so, you'll need to a different medication than fluconazole (Diflucan) because it's only used to treat certain fungal infections.

            • If you're able to become pregnant, you're recommended to use effective birth control during fluconazole (Diflucan) treatment and for at least 1 week after your last dose. There's a chance that fluconazole (Diflucan) can cause birth defects.

              More tips for fluconazole (Diflucan) oral suspension

              • Shake the oral suspension each time before you measure out and take your dose.

                • Only use the measuring device provided at the pharmacy. Don't use household spoons to measure your dose since this could cause you to take the wrong amount.

                  • Store fluconazole (Diflucan) at room temperature. The suspension is good for 2 weeks from when you receive it from the pharmacy. Throw the medication away after 2 weeks, even if there's still some left over.

                    Frequently asked questions about Fluconazole (Diflucan)

                    Is fluconazole (Diflucan) an antibiotic?
                    No, fluconazole (Diflucan) is an antifungal, meaning it treats infections caused by fungus. Antibiotics, however, are used to treat infections caused by bacteria.
                    How long does fluconazole (Diflucan) take to work?
                    How long it takes for fluconazole (Diflucan) to work depends on different factors, such as the type of infection you're taking it to treat and how serious it is. For example, if you're taking fluconazole (Diflucan) for a vaginal yeast infection, your symptoms should improve within 1-3 days. But if you're taking fluconazole (Diflucan) for oral thrush, your might need to continue treatment for several days before you notice any improvement. Continue taking fluconazole (Diflucan) for the amount of time your prescriber recommended, even if you start to feel better. Stopping treatment too early can cause your infection to come back or be harder to treat.
                    How often can you take fluconazole (Diflucan) for a vaginal yeast infection?
                    The typical dose for treating a vaginal yeast infection is fluconazole (Diflucan) 150 mg by mouth once as a single dose. If your symptoms don't go away within 3 days after the dose, your HCP will instruct you to take a dose of fluconazole (Diflucan) every 3 days for a total of 3 doses. But if you have vaginal yeast infections more than 3 times within a year, your HCP might ask you to take fluconazole (Diflucan) daily for a longer period of time to control the infection. Ask your healthcare team if you've more questions about how long you should take this medication.
                    Does fluconazole (Diflucan) treat bacterial vaginosis (BV)?
                    No, fluconazole (Diflucan) doesn't treat bacterial vaginosis (BV). BV is a bacterial infection, so it's treated with antibiotics like metronidazole (Flagyl) or clindamycin (Clindesse) vaginal cream. Fluconazole (Diflucan) is an antifungal, so it doesn't work for bacterial infections, just fungal infections. Symptoms of a vaginal yeast infection and BV are similar (e.g., itching, burning, irritation), so make sure to check with your gynecologist if you have these symptoms. They'll make sure you receive the most appropriate treatment for your condition.
                    Can you drink alcohol while taking fluconazole (Diflucan)?
                    You should avoid drinking alcohol until you've finished your course of fluconazole (Diflucan). Drinking alcohol can weaken your immune system and make it harder to recover from an infection. Additionally, drinking alcohol while taking fluconazole (Diflucan) raises your risk for stomach-related side effects (e.g., nausea, vomiting, diarrhea) as well as the risk for liver problems. If avoiding alcohol isn't possible for you, talk to your prescriber about what's a reasonably safe amount of alcohol to drink while taking fluconazole (Diflucan).
                    Can you take fluconazole (Diflucan) while pregnant?
                    Typically, HCPs will avoid prescribing fluconazole (Diflucan) for people who are pregnant unless they have a serious infection that can't be treated with a safer option. Research shows taking higher doses of fluconazole (Diflucan) regularly during pregnancy can cause harm to unborn babies. While the same risk isn't linked to the single 150 mg dose of fluconazole (Diflucan) for vaginal yeast infections, it's also not recommended during pregnancy because of potential harm. Talk with your healthcare team if you have questions about fluconazole (Diflucan) and pregnancy.
                    How long do fluconazole (Diflucan) side effects last?
                    How long the side effects of fluconazole (Diflucan) last depends on what symptoms you're experiencing and whether they can be managed with lifestyle changes or other medications. For example, one of the more common side effects of fluconazole (Diflucan) is headache, which typically goes away on its own. But in the meantime, you can ease headache by drinking enough water or taking an over-the-counter pain medication that's safe for you. Another example is that taking fluconazole (Diflucan) can raise the risk for liver problems. This side effect is rare and typically don't lead to symptoms, but your HCP might ask you to avoid drinking alcohol while you're taking fluconazole (Diflucan) to minimize the risk of serious liver damage. Talk to your healthcare team if you're concerned with certain side effects of fluconazole (Diflucan).
                    How long does fluconazole (Diflucan) stay in your system?
                    It takes about 6 days for most of fluconazole (Diflucan) to leave your body after a dose. This timeframe is estimated based on the half-life of fluconazole (Diflucan). But if you have kidney problems, it can take up to 20 days for the body to remove fluconazole (Diflucan). Because this medication can stay in the body for a long time and has the potential to cause birth defects, anyone who is able to become pregnant should use birth control until at least a week after their last dose. Talk with your healthcare team if you have specific concerns about how long this medication might stay in your body.

                    What are the risks and warnings for Fluconazole (Diflucan)?

                    Fluconazole (Diflucan) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.

                    risk-warning

                    Liver damage

                    • Risk factors: Liver problems | Excessive alcohol use

                      Although rare, people who took fluconazole (Diflucan) have developed liver problems. Because of this risk, your prescriber might order blood tests before you start and during treatment to check your liver function tests to make sure your liver is healthy. Also, it's recommended to limit or avoid alcohol because it can also cause liver damage. Get medical attention right away if you notice yellowing of your skin or the whites of your eyes; stool changes; dark or brown urine; swelling of your stomach; stomach pain; or confusion. Your prescriber might ask you to stop taking fluconazole (Diflucan) in order to prevent further liver damage.

                      risk-warning

                      Allergic reaction

                      Severe allergic reactions to fluconazole (Diflucan) are possible, including life-threatening reactions like facial swelling, hives, and anaphylaxis (e.g., closing of the throat). If you notice difficulty breathing; a choking sensation; dizziness; fast heartbeat; nausea; or swelling around your eyes, lips, or tongue after taking fluconazole (Diflucan), get medical attention right away.

                      risk-warning

                      Severe skin reaction

                      Very rarely, people have developed a serious, potentially life-threatening skin reaction called exfoliative dermatitis after starting fluconazole (Diflucan). This serious rash can cause itchiness, redness all over your body, and scaly and peeling skin. Get medical help right away if you notice a new or severe rash with fever, skin redness, or unexplained blisters.

                      risk-warning

                      Harm to unborn babies

                      It's generally recommended to avoid using fluconazole (Diflucan) while pregnant unless there's a clear need for the medication. While there haven't been a lot of studies about the safety of fluconazole (Diflucan) during pregnancy, the studies that are available suggest there's a small chance it can cause harm to babies. Examples include problems in the heart, head, face, and bones. If you're taking 400 mg to 800 mg of fluconazole (Diflucan) per day, it's recommended to use birth control during treatment and for 1 week after your last dose. If you become pregnant while you're taking fluconazole (Diflucan), stop taking the medication right away and talk to your prescriber about the risks and benefits of continuing to use the medication.
