The straightforward answer to the question ‘Can I take fluconazole with Suboxone?’ is no. Suboxone treatment is a common medication used to treat opioid dependence. Conversely, fluconazole is an antifungal medication used to treat yeast and fungal infections. Despite their unrelated purposes, as they break down in the body, they exacerbate each other’s detrimental effects. As fluconazole impacts liver function, it results in fluctuations in the levels of Suboxone in the body. The main side effects of mixing these two can be drowsiness, lightheadedness, and breathing issues.
If you are taking fluconazole already and your opioid dependence requires you to take Suboxone, call 844.445.2565 our DEA-certified care providers before starting!

How Fluconazole and Suboxone Are Metabolized
To fully understand the answer to Can I take fluconazole with Suboxone, you need to know how these substances are metabolized in the body
| Medications | Breakdown in the Body |
|---|---|
| Fluconazole | The half-life of fluconazole is approximately 25 hours. It inhibits the CYP3A4 isoenzyme moderately, which is present in the liver and small intestine. This gene plays a role in the interaction and elimination of most of the prescribed drugs. 1That’s why there are fluconazole interactions with other drugs that break down at this site. |
| Suboxone | The isozyme CYP3A4 enables the breakdown of buprenorphine into norbuprenorphine in the liver. Azole antifungal medications, such as fluconazole and ketoconazole, are inhibitors of the liver enzyme CYP3A4. Due to this, they increase buprenorphine concentrations in the body. Therefore, you may experience suboxone side effects more intensely. |
