Pizofen-TS 1.5mg 10pcs

Indications

Pizotifen is used to treat vascular headaches of the migraine type, such as classical migraine, common migraine, and cluster headache, as a preventative measure. It is ineffective in stopping migraine attacks after they have started.

Pharmacology

The role of Pizotifen is to inhibit the peripheral effects of serotonin and histamine, increase the permeability of the cranial blood vessel membrane and the exudation of plasma kinin, and at the same time change the pain threshold of migraine. By blocking 5HT receptors, pizotifen attenuates serotonin signaling by causing cranial vasoconstriction and serotonin-enhanced platelet function and aggregation. There is evidence that it also inhibits the peripheral effects of bradykinin. Pizotifen can inhibit the reuptake of serotonin by platelets, thereby affecting tension and reducing passive dilation of extracranial arteries. The effect of pizotifen in causing appetite stimulation may be due to the drug acting on the metabolic level rather than directly stimulating the appetite center.

Dosage & Administration

Adults: Usually 1.5 mg daily. This may be taken as a single dose at night or in three divided doses. Dosage should be adjusted to the individual patient requirements up to a maximum of 4.5 mg daily. Up to 3 mg may be given as a single dose.

Children (aged over 2 years): Up to 1.5 mg daily, usually as a divided dose, although up to 1 mg has been given as a single dose at night.

Interaction

Pizotifen may augment the central effects of sedatives, hypnotics, antihistamines (including several common cold remedies), and alcohol. The hypotensive impact of adrenergic neuron blockers is counteracted by pizotifen.

Contraindications

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

Side Effects

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

Pregnancy & Lactation

The use of Pizotifen during pregnancy is unknown, however, no adverse consequences have been observed. As a result, the medicine should only be used during pregnancy if the potential benefit to the mother outweighs the danger to the fetus. Pizotifen has not been proven to be safe during nursing, thus mothers should avoid taking it during breastfeeding.

Precautions & Warnings

Renal impairment and urinary retention should be considered. Drowsiness can impair your ability to drive a car or operate machinery. Pizotifen boosts the effects of alcohol.

Storage Conditions

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