Zofen TS 1.5mg Tablet 1 Strip

Zofen TS is indicated as a prophylactic treatment for vascular headache of migraine type, such as classical migraine, common migraine, and cluster headache. It is not effective in relieving migraine attacks once in progress.

Pizotifen works by inhibiting the peripheral actions of serotonin and histamine in increasing the membrane permeability of cranial vessels and transudation of plasmakinin, while altering pain thresholds in migraines. By blocking 5-HT receptors, pizotifen attenuates the signalling of serotonin in causing cranial vasoconstriction, as well as serotonin-enhanced platelet function and aggregation. There is evidence that it also inhibits the peripheral actions of bradykinin. Pizotifen may inhibit serotonin reuptake by blood platelets, which affects the tonicity and decreases passive distension of extracranial arteries. The effects of pizotifen leading to appetite stimulation may be due to the drug acting at the metabolic level rather than a direct stimulation of the appetite centre.

The central effects of sedatives, hypnotics, antihistamines (including certain common cold preparations) and alcohol may be enhanced by Zofen TS. Zofen TS antagonizes the hypotensive effect of adrenergic neurone blockers.

Pizotifen is contraindicated in patients with known hypersensitivity to any of its ingredients.

The most common side effects are appetite-stimulating effect, increase in body weight, and drowsiness.

Information on using Pizotifen in pregnancy is limited, although no ill effects have been reported. The drug should therefore only be given during pregnancy if the potential benefit to mother justifies the potential risk to the fetus. The safety of Pizotifen during lactation has not been established, so mothers should avoid taking it when breastfeeding.

Urinary retention and renal impairment should be taken into consideration. Drowsiness may affect the performance of driving vehicles & operation of machinery. Zofen TS enhances the action of alcohol.

Keep in a dry place away from light and heat. Keep out of the reach of children.
