Frovatriptan (Frova) is a 5 HT-1 receptor agonist commonly called "Triptans". It causes intracranial vasoconstriction and is indicated for the treatment of patients with acute migraine attack. Frovatriptan has a very long half-life compared to other triptans (about five times that of other triptans) and hence, it may be indicated for the short-term prophylaxis of female patients with menstrual migraine.

• Hepatic impairment severe
• There is not much evidence of triptan cross-reactivity.

Warnings and precautions

• Anaphylactoid and Anaphylactic reactions:

  • There may be anaphylaxis, anaphylactoid responses, and hypersensitivity reactions (including edoema).

• Cardiac events

  • Administration of 5-HT-1 agonist has been associated with cardiac arrest, heart failure, transient ischemia and myocardial injury.
  • Stop side effects developing
  • Patients who suffer chest discomfort, pressure, tightness, or other symptoms that suggest angina should be checked for Prinzmetal's or CAD before continuing with medication.
  • If the patient experiences the same symptoms after treatment, ECG monitoring should be performed.
  • It is not advised for patients with vasospastic or ischemic CAD, Wolff-Parkinson-White syndrome, or arrhythmias linked to various diseases of the cardiac accessory conduction pathways.

• Cerebrovascular events

  • Contraindicated if you have a history of TIA/CVA.
  • Five-HT-1 agonist administration has been linked to strokes and cerebral/subarachnoid hemorhage (some fatal).

• High blood pressure

  • Hypertension rarely with end-organ damage, or markedly elevated blood pressure.
  • Contraindicated in conjunction with uncontrolled hypertension

• Headaches

  • If you take your medication for more than 10 days per month, withdrawal headaches can occur.

• Vasospasm-related events

  • Raynaud syndrome, gastrointestinal and peripheral vascular infarction, and infarction.

• Visual effects

  • There have been cases of partial and complete (reversible or irreversible) but no clear relationship.

• Coronary artery disease

  • Patients at high risk of developing CAD should be avoided (eg, hypertension and hypercholesterolemia; smoking obesity, diabetes, strong family history, men >40 years old, hypertension, smoking, or other factors that could increase the likelihood of developing CAD).
  • Contraindicated for CAD and coronary artery vasospasm
  • Before starting treatment, a cardiac evaluation is required. If you are using long-term treatment, follow up with periodic evaluation.

• Hepatic impairment

  • There are no data available. Please be careful.
