minor Known Drug Interaction
Calcium channel blockers : Certain calcium channel antagonists (nifedipine, isradipine, amlodipine, verapamil, and felodipine) are metabolized by CYP3A4.
Norvasc
Diflucan
Amlodipine (Norvasc) is a drug that lowers blood pressure and treats chest pain. It belongs to a class of drugs called calcium channel blockers.
Fluconazole is an antifungal medicine. It is used to treat infections caused by fungus.
This medicine treats high blood pressure (hypertension). Lowering blood pressure reduces the risk of strokes and heart attacks. Amlodipine also treats chest pain (angina) caused by coronary artery disease, including chronic stable angina and vasospastic angina.
Fluconazole treats vaginal yeast infections. It also treats yeast infections in the mouth and esophagus. Fluconazole can also treat urinary tract infections, peritonitis, systemic Candida infections, and pneumonia. It can also treat cryptococcal meningitis. Fluconazole can also prevent candidiasis in patients undergoing bone marrow transplantation.
Amlodipine blocks calcium from entering heart and blood vessel cells. This relaxes and widens blood vessels, making it easier for blood to flow. As a result, the heart does not have to work as hard, which lowers blood pressure and reduces chest pain.
Fluconazole works by stopping the growth of fungi. It blocks the fungus from producing a substance it needs to grow. This helps to clear up the infection.

Amlodipine may cause low blood pressure, especially if you have severe aortic stenosis. Some people with severe heart disease may experience worsening chest pain or a heart attack when starting or increasing the dose of amlodipine. If you have severe liver problems, your doctor will increase your dose slowly.
Coadministration of other drugs known to prolong the QT interval and which are metabolized via the enzyme CYP3A4 such as erythromycin, pimozide, and quinidine are contraindicated in patients receiving fluconazole.
Tell your doctor if you are pregnant or plan to become pregnant. High blood pressure during pregnancy can harm both the mother and the baby. Amlodipine passes into breast milk, but no harmful effects on the breastfed infant have been seen.
Tell your doctor if you are pregnant or plan to become pregnant. Fluconazole may not be safe for your baby. Talk to your doctor about breastfeeding while taking fluconazole.

How to Read This amlodipine vs fluconazole Comparison
amlodipine is classified in the Calcium Channel Blocker drug class, while fluconazole sits within the Azole Antifungal class. Drugs from different classes work through distinct mechanisms, so a head-to-head comparison illustrates trade-offs rather than equivalence. Both drugs are prescription-only, so a licensed provider must authorize use.
Adverse event totals above are pulled from the FDA's Adverse Event Reporting System (FAERS). For these top-ranked reactions alone, amlodipine has 67,050 submissions while fluconazole has 17,630. Those figures reflect cumulative reporting volume, not per-patient risk, so older, widely dispensed drugs typically look worse on count alone. These two drugs have a known minor interaction flagged in FDA labeling, attributed to fluconazole blocks the enzymes that break down amlodipine, which can lead to higher levels of the blood pressure medicine in your body.. Serious warnings, pregnancy guidance, and contraindications can differ even when indications overlap.
A table cannot represent individual circumstances. Data here is sourced from FDA Structured Product Labels (SPL) and FAERS, both of which update as manufacturers and clinicians submit new information. This registry does not provide medical, treatment, substitution, or medication-change directions for amlodipine or fluconazole.
