Storing Fluconazole, and how long it keeps

Quoted from this product’s own FDA label. Storage belongs to the product and its device, not to the drug in general — a pen and a tablet of the same medicine are kept completely differently.

• “After reconstitution: Store suspension between 30°C (86°F) and 5°C (41°F) and discard unused portion after 2 weeks.”
• “Store reconstituted suspension between 30°C (86°F) and 5°C (41°F) and discard unused portion after 2 weeks.”
• “After reconstitured: Store suspension between 30°C (86°F) and 5°C (41°F) and discard unused portion after 2 weeks.”

How long does Fluconazole stay in your body?

The elimination half-life of fluconazole is about 30 hours (range 20 to 50 hours) — the time it takes the body to clear about half of it. As a rule of thumb, a medicine is mostly gone after roughly 4 to 5 half-lives, though this varies from person to person with age and kidney or liver function. Kidney function is the main driver: the label reports an inverse relationship between the elimination half-life and creatinine clearance, so the half-life is markedly prolonged in renal impairment (and tends to be longer in older adults, whose kidney clearance declines). No active metabolite outlasts the parent — fluconazole is cleared mostly unchanged by the kidneys (about 80% excreted unchanged in urine, only ~11% as metabolites). Not a prodrug.

This is general information, not medical advice. It doesn’t tell you when a drug test would read negative (tests detect substances for different, often longer, windows) or when it’s safe to take another dose — ask your pharmacist or prescriber.

Frequently asked questions

What does Fluconazole treat?

Fluconazole (Fluconazole) may be used to treat blastomycosis, chronic mucocutaneous candidiasis, oral candidiasis, vulvovaginal candidiasis, coccidioidomycosis, histoplasmosis, based on NIH RxClass drug-classification data (conditions a drug may treat — not a verbatim copy of the FDA-approved label). This is general reference, not medical advice.

How does Fluconazole work?

Fluconazole is a azole antifungal. Azole antifungals block a fungal enzyme (lanosterol 14-alpha-demethylase) that the fungus needs to make ergosterol, a key building block of its cell membrane. Without enough ergosterol the membrane becomes leaky and unstable, which stops the fungus from growing and can cause it to break apart and die.

How much does Fluconazole cost?

Nobody can tell you what you will pay — your price is set by your insurer's formulary, your deductible and the pharmacy's markup, and none of those are published. What IS published is what the pharmacy paid to acquire it: about $0.42 per ml, per the CMS NADAC survey. Treat that as the floor, not the quote — ask the pharmacist for the cash price as well as your copay, because for cheap generics the cash price often wins. Pharmacies pay less for a same-class option, Clotrimazole — about $0.21 on the same basis.

Is there a coupon or discount for Fluconazole?

pharmaranks is an independent ratings site, not a pharmacy — we don't issue coupons or sell Fluconazole. To pay less, Fluconazole is already a generic — usually the lowest-cost version — so the main levers are comparing cash prices between pharmacies and using a pharmacy discount-card service. Prices vary by pharmacy, insurance, and location, so always confirm at the counter. This is general reference, not medical or financial advice.
