Frova (Frovatriptan Succinate) - Drug Interactions, Contraindications, Overdosage

DRUG INTERACTIONS

Drug Interactions (see also CLINICAL PHARMACOLOGY, Drug Interactions)

Ergot-containing drugs have been reported to cause prolonged vasospastic reactions. Due to a theoretical risk of a pharmacodynamic interaction, use of ergotamine-containing or ergot-type medications (like dihydroergotamine or methysergide) and FROVA within 24 hours of each other should be avoided (see CONTRAINDICATIONS).

Concomitant use of other 5HT_1B/1D agonists within 24 hours of FROVA treatment is not recommended (see CONTRAINDICATIONS).

Selective Serotonin Reuptake Inhibitors / Serotonin Norepinephrine Reuptake Inhibitors and Serotonin Syndrome: Cases of life-threatening serotonin syndrome have been reported during combined use of selective serotonin reuptake inhibitors (SSRIs) or serotonin norepinephrine reuptake inhibitors (SNRIs) and triptans. (See WARNINGS).

OVERDOSAGE

There is no direct experience of any patient taking an overdose of FROVA. The maximum single dose of frovatriptan given to male and female patients with migraine was 40 mg (16 times the clinical dose) and the maximum single dose given to healthy male subjects was 100 mg (40 times the clinical dose) without significant adverse events.

As with other 5-HT₁ receptor agonists, there is no specific antidote for frovatriptan. The elimination half-life of frovatriptan is 26 hours, therefore if overdose occurs, the patient should be monitored closely for at least 48 hours and be given any necessary symptomatic treatment.

The effects of hemo- or peritoneal dialysis on blood concentrations of frovatriptan are unknown.

CONTRAINDICATIONS

FROVA should not be given to patients with ischemic heart disease (e.g. angina pectoris, history of myocardial infarction, or documented silent ischemia), or to patients who have symptoms or findings consistent with ischemic heart disease, coronary artery vasospasm, including Prinzmetal’s variant angina or other significant underlying cardiovascular disease (see WARNINGS).

FROVA should not be given to patients with cerebrovascular syndromes including (but not limited to) strokes of any type as well as transient ischemic attacks.

FROVA should not be given to patients with peripheral vascular disease including (but is not limited to) ischemic bowel disease (see WARNINGS)

FROVA should not be given to patients with uncontrolled hypertension (see WARNINGS).

FROVA should not be administered to patients with hemiplegic or basilar migraine.

FROVA should not be used within 24 hours of treatment with another 5-HT₁ agonist, an ergotamine containing or ergot-type medication such as dihydroergotamine (DHE) or methysergide.

FROVA is contraindicated in patients who are hypersensitive to frovatriptan or any of the inactive ingredients in the tablets.
