How to take Diflucan tablets correctly
How a tablet is swallowed matters for absorption, gastric tolerance and avoiding oesophageal irritation. Diflucan (Fluconazole) at 50mg, 100mg, 150mg, 200mg is straightforward to take for most adults but a few practical points reduce variability and minimise local side effects.
Standard administration of Diflucan
Most capsule, oral suspension of Fluconazole are taken whole with a full glass of water (about 200 mL). Sitting or standing upright for 10–15 minutes after dosing reduces the risk of the tablet lodging in the oesophagus and causing local irritation. Sufficient water carries the medication into the stomach where dissolution and absorption begin.
Practical tips and what to avoid
According to the prescribing information for Fluconazole, taking Diflucan with too little water or while lying down increases oesophageal exposure and can cause heartburn-like irritation in susceptible users. Lukewarm or cool water is preferable to very hot water. Tablets should not be chewed unless explicitly authorised by the prescriber for the formulation; Fluconazole is a triazole antifungal that inhibits the cytochrome P450-dependent enzyme lanosterol 14-alpha-demethylase, blocking the synthesis of ergosterol from lanosterol.

A full glass — about 200 mL — is the standard recommendation for Diflucan at 50mg, 100mg, 150mg, 200mg. Less water increases the risk of the tablet sticking on the way down and causing local irritation.
Can I take Diflucan without water? ▾
It is not advisable. Tablets without water can lodge in the oesophagus and cause local irritation; some formulations require water for proper dissolution. Always take Diflucan with adequate water unless the formulation explicitly says otherwise.
