"March 11, 2014 - The U.S. Food and Drug Administration allowed marketing of the first device as a preventative treatment for migraine headaches. This is also the first transcutaneous electrical nerve stimulation (TENS) device specifically "...

Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
FROVA was evaluated in four randomized, double-blind, placebo-controlled, short-term trials. These trials involved 2392 patients (1554 on FROVA 2.5 mg and 838 on placebo). In these short-term trials, patients were predominately female (88%) and Caucasian (94%) with a mean age of 42 years (range 18 -69).The treatment-emergent adverse events that occurred most frequently following administration of FROVA 2.5 mg (i.e., in at least 2% of patients), and at an incidence ≥ 1% greater than with placebo, were dizziness, paresthesia, headache, dry mouth, fatigue, flushing, hot or cold sensation, dyspepsia, skeletal pain, and chest pain. In a long term, open-label study where 496 patients were allowed to treat multiple migraine attacks with FROVA 2.5 mg for up to 1 year, 5% of patients (n=26) discontinued due to treatment-emergent adverse events.
Table 1 lists treatment-emergent adverse events reported within 48 hours of drug administration that occurred with FROVA 2.5 mg at an incidence of ≥ 2% and more often than on placebo, in the four placebo-controlled trials. The events cited reflect experience gained under closely monitored conditions of clinical trials in a highly selected patient population. In actual clinical practice or in other clinical trials, these incidence estimates may not apply, as the conditions of use, reporting behavior, and the kinds of patients treated may differ.

within 48 Hours (Incidence ≥ 2% and Greater Than Placebo) of
Patients in Four Pooled Placebo-Controlled Migraine Trials
|Adverse events||FROVA 2.5 mg
|Central & peripheral nervous system|
|Gastrointestinal system disorders|
|Body as a whole – general disorders|
|Hot or cold sensation||3%||2%|
The incidence of adverse events in clinical trials did not increase when up to 3 doses were used within 24 hours. The incidence of adverse events in placebo-controlled clinical trials was not affected by gender, age or concomitant medications commonly used by migraine patients. There were insufficient data to assess the impact of race on the incidence of adverse events.
Other Events Observed in Association with the Administration of FROVA
The incidence of frequently reported adverse events in four placebo-controlled trials are presented below. Events are further classified within body system categories. Frequent adverse events are those occurring in at least 1/100 patients.
Central and peripheral nervous system: dysesthesia and hypoesthesia.
Gastrointestinal: vomiting, abdominal pain and diarrhea.
Body as a whole: pain.
Psychiatric: insomnia and anxiety.
Vision disorders: vision abnormal.
Skin and appendages: sweating increased.
Hearing and vestibular disorders: tinnitus.
Heart rate and rhythm: palpitation.
The following adverse reactions were identified during post approval use of FROVA. Because these events are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
Central and peripheral nervous system: Seizure.

Ergot-containing drugs have been reported to cause prolonged vasospastic reactions. Because these effects may be additive, use of ergotamine-containing or ergot-type medications (like dihydroergotamine or methysergide) and FROVA within 24 hours of each other is contraindicated [see CONTRAINDICATIONS].
Because their vasospastic effects may be additive, co-administration of FROVA and other 5-HT1 agonists (e.g., triptans) within 24 hours of each other is contraindicated [see CONTRAINDICATIONS].
Selective Serotonin Reuptake Inhibitors / Serotonin Norepinephrine Reuptake Inhibitors and Serotonin Syndrome
Cases of serotonin syndrome have been reported during combined use of triptans and SSRIs, SNRIs, TCAs, and MAO inhibitors [see WARNINGS AND PRECAUTIONS].
