Second-generation H1 antihistamine
How to take Loratadine tablets correctly
How a tablet is swallowed matters for absorption, gastric tolerance and avoiding oesophageal irritation. Loratadine (Loratadine) at 5mg, 10mg is straightforward to take for most adults but a few practical points reduce variability and minimise local side effects.
Standard administration of Loratadine
Most tablet, oral syrup, orodispersible tablet of Loratadine 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 Loratadine, taking Loratadine 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; Loratadine selectively blocks peripheral H1 histamine receptors, antagonising the effects of histamine released during allergic reactions.
