Flu 150 (Fluconazole 150mg): Guide for Fungal Infection

Fluconazole 150mg is a single-dose oral triazole antifungal formulated to treat localised and systemic candidal infections. In the UK, generic Flu 150 offers a bioequivalent alternative to Diflucan, delivering identical active drug absorption.

Key Takeaways

Active Salt: Fluconazole 150mg (Triazole Antifungal). Primary Indications: Acute vaginal thrush and candidal balanitis. Legal Status: This medicine is classed as either Prescription-Only (POM) or Pharmacy (P), depending on the specific product. Clinical Benefit: Single-dose oral therapy bioequivalent to Diflucan.

Pharmacological Mechanism of Action

Fluconazole selectively inhibits fungal cytochrome P450-dependent 14α-demethylase (CYP51). The conversion of lanosterol to ergosterol is halted through this action. The fungal cell membrane consequently becomes disrupted, which brings about cellular lysis.

Clinical Uses

Prescribers select Fluconazole 150mg for acute fungal indications managed under NHS and NICE pathways:

Vaginal Candidiasis: Acute vulvovaginal thrush in adult women. Candidal Balanitis: This refers to fungal inflammation affecting the glans penis. Mucosal Candidiasis: Oropharyngeal or oesophageal yeast infections.

Medicine Interactions with Flu 150

The hepatic enzymes CYP2C9 and CYP3A4 are potently inhibited by Fluconazole. Co-administration requires clinical caution: Warfarin & Coumarins: Enhances anticoagulant effects, elevating INR and bleeding risk. Phenytoin: Inhibits phenytoin clearance, risking toxicity. Rifampicin: Accelerates fluconazole clearance, requiring potential dose adjustments.

Safety Information

Fluconazole is generally well tolerated, but side effects occur. Always consult a qualified healthcare professional before starting or changing treatment.

Clinical Safety Advice

Hepatic Impairment

Baseline liver enzymes may require monitoring in patients with pre-existing hepatic disease.

Renal Impairment

Plasma clearance is reduced; prescribers adjust dosage based on creatinine clearance.

Pregnancy and Lactation

Contraindicated during pregnancy due to potential teratogenic risks unless clinically essential.

Accessing Treatment Safely in the UK
