Dual 5α-reductase inhibitor (type 1 and type 2)
How to take Dutasteride tablets correctly
How a tablet is swallowed matters for absorption, gastric tolerance and avoiding oesophageal irritation. Dutasteride (Dutasteride) at 0.5mg is straightforward to take for most adults but a few practical points reduce variability and minimise local side effects.
Standard administration of Dutasteride
Most capsule of Dutasteride 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 Dutasteride, taking Dutasteride 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; Dutasteride irreversibly inhibits both isoenzymes of 5α-reductase, the enzyme that converts testosterone to dihydrotestosterone (DHT).
Frequently asked questions
How much water should I take with Dutasteride? ▾
A full glass — about 200 mL — is the standard recommendation for Dutasteride at 0.5mg. Less water increases the risk of the tablet sticking on the way down and causing local irritation.
Can I take Dutasteride 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 Dutasteride with adequate water unless the formulation explicitly says otherwise.
