Overview
Fluconazole is an antifungal drug that doctors use to treat or prevent various types of fungal and yeast infections, such as:
- vaginal yeast infections
- oral yeast infections (oral thrush)
- fungal skin infections
- fungal meningitis
Fluconazole comes in different forms, including oral tablets, oral suspension, and injection. It is available as a generic drug or under the brand name Diflucan.

What foods interfere with fluconazole?
The prescribing information for fluconazole (Diflucan) does not list any foods that are known to affect the absorption of this drug. So, you should be able to eat and drink as usual while taking fluconazole.
Although you may have heard milk, coffee, and grapefruit as things that you need to avoid while taking fluconazole, research only shows a possible interaction between fluconazole and caffeine, which is found in coffee.
Some sources may suggest that milk and grapefruit affect the body’s ability to absorb fluconazole, but research shows that fluconazole’s absorption is not affected by food or the pH levels in your stomach.
Some research, however, suggests that a balanced diet and improved gut microbiome — the healthy bacteria and other organisms that live in your gut — may help reduce fungal infections and therefore support fluconazole treatment. This may mean avoiding foods high in processed sugars and saturated fats.

Get free cardCan I drink coffee with fluconazole?
Fluconazole may interact with caffeine, and caffeine is found in coffee. Fluconazole may slow down the way your body clears out caffeine. This could increase your risk of experiencing side effects of caffeine. Some common side effects of caffeine may include:
- feeling jittery
- fast heartbeat
- anxiety
Because of this, your doctor may recommend limiting the amount of caffeine you consume while you’re taking fluconazole. However, this may not be necessary for everyone. Some 2023 research suggests that caffeine may even support treatment with fluconazole.
Examples of foods and beverages that contain caffeine include:
- coffee
- tea
- chocolate
- sodas
- energy drinks
If you’d like to learn more about drinking coffee or consuming caffeine during your treatment with fluconazole, talk with a doctor.
Can I drink milk while taking fluconazole?
Despite some claims that drinking milk can limit your body’s absorption of fluconazole, the drug’s prescribing information does not list any foods or drinks that are known to affect the absorption of this drug. So, you should be able to continue to drink milk as usual.
It may be worth noting that the Candida diet sometimes recommends limiting the intake of milk and some other dairy products. In theory, galactose (a type of sugar found in milk sugars) may encourage Candida to grow. However, there is not enough research to confirm this yet.
The Candida diet is meant to limit foods and drinks with the potential to increase Candida growth. Candida is the most common fungus in the human body. Although it’s generally harmless, too much of this fungus can lead to infections such as vaginal yeast infections and other fungal infections that fluconazole is prescribed to treat.
What drugs interact with fluconazole?
Although there are no foods known to interact with fluconazole, several other medications may interact with the drug. Some medications that may affect fluconazole include:
- some antibiotics, like azithromycin (Zithromax)
- some antidepressants, like citalopram (Celexa)
- some diabetes medications, like glipizide (Glucotrol XL)
- some antipsychotics, like haloperidol (Haldol)
- some immunosuppresants, like cyclosporine (Neoral)
- some statins
Some of these medications may increase the risk of fluconazole side effects, while others may see their own side effects increase. Before starting fluconazole, always speak with a doctor about your other medications to avoid any possible interactions.
