Sumatriptan (Imitrex) is used for the rapid relief of headache due to migraine or cluster headache. It belongs to the class of drugs called selective serotonin receptor agonists. Other medications in the same class include:

• Naratriptan (Amerge),
• Zolmitriptan (Zomig),
• Rizatriptan (Maxalt),
• Almotriptan (Axert),
• Frovatriptan (Frova), and
• Eletriptan (Relpax)

Sumatriptan (Imitrex) Uses:

• Acute treatment of Cluster headache: SubQ (excluding Zembrace):

  • It is used for the acute treatment of cluster headache episodes in adults as a single agent or combined with 100% oxygen.

• Moderate to severe acute Migraine:

  • Intranasal, Oral, SubQ: It is indicated for the acute treatment of migraine with or without aura in adults

Sumatriptan (Imitrex) Dose in Adults

Note:

• Limit use to less than 10 days every month to avoid over-medication headache.
• Do not use Triptans within 24 hours of the use of an ergotamine preparation or a different triptan.

Sumatriptan (Imitrex) Dose in the treatment of acute Cluster headache:

Note: As single agent or combined with 100% oxygen. Some experts recommend initial treatment with only 100% oxygen if available.

• SubQ (preferred route):
  • Initial: 6 mg once; 3 mg may be just as effective in some patients.
  • If initial dose was effective but headache recurs, may repeat a dose (usually same as first dose) after ≥1 hour;
  • some experts recommend waiting ≥2 hours before repeat dose.
  • Maximum dose: 6 mg per dose; 12 mg in 24 hours.
• Intranasal Solution (alternative route) (off-label):
  • Initial: 20 mg administered once in the nostril opposite the headache's side.
  • If the first dose worked but the headache returned, you could try again in about two hours.
  • 40 mg in 24 hours is the maximum dose.

Note:

• According to some experts, when treating acute cluster headache, following initial treatment for prevention of cluster headaches, patients with ≥2 headaches per day may temporarily receive >2 doses of sumatriptan in one day (either SubQ or intranasal at the usual dose and interval) until prophylaxis becomes effective.

Sumatriptan (Imitrex) Dose in the treatment of Acute moderate to severe Migraine:

Note:

• As single agent or combined with an NSAID (eg, naproxen).
• Administer at first sign of headache.
• When attack is complicated by vomiting or severe nausea, it is prefered to use non-oral preparation.
• Oral: Initial: Usual:
  • 50–100 mg all at once.
  • The same dose may be given again after around two hours if the first dose was only partially successful or the headache returned.
  • 100 mg maximum per dose; 200 mg maximum per day.

Sumatriptan (Imitrex) Dose in Children

Sumatriptan (Imitrex) Dose in the treatment of Migraine:

Note:

• Results of clinical studies are mixed with regards to efficacy, particularly with oral and SubQ sumatriptan doses; a 2004 practice parameter concluded that sumatriptan nasal spray was effective for the acute treatment of migraines in adolescent patients.

• Intranasal:

  • Children 5 to 12 years: Limited data available:

    • Customized dose of 5 mg, 10 mg, or 20 mg administered in one nostril as a single dose as soon as possible after the onset of migraine.
    • Weight-based dosing regimen:
      • Body weight: 20 to 39 kg: 10 mg/dose;
      • body weight ≥40 kg: 20 mg/dose;
      • however, relatively few children <12 years old were included in the study.
    • Intranasal dosages of 20 mg/dose were employed in a short, randomised, double-blind, placebo-controlled research involving 14 kids (range: 6 to 9 years; median: 8.2 years).

  • Children ≥12 years and Adolescents ≤17 years: Limited data available:

    • As soon as possible after the commencement of a migraine, 5 mg, 10 mg, or 20 mg should be delivered in one nostril as a single dose; the dosage should be customised.

  • Adolescents ≥18 years: Initial single dose:

    • Powder: (Onzetra Xsail):
      • 22 mg (11 mg nosepiece in each nostril).
      • If dose partially effective or headache recurs, same dose may be repeated if more than two hours have elapsed since initial dose (maximum: 44 mg [4 nosepieces] per 24 hours or 22 mg [2 nosepieces] and one dose of another sumatriptan product [separated by ≥2 hours] per 24 hours).
      • It has not been shown safe to cure more than four headaches on average in a 30-day span.
    • Solution:
      • 5 mg, 10 mg, or 20 mg administered in one nostril as soon as possible after the onset of migraine; the dose should be customized according to patient need.
      • A 10 mg dose may be administered as 5 mg in each nostril.
      • If dose partially effective or headache recurs, the same dose may be repeated if more than two hours have elapsed since initial dose, not to exceed a total daily dose of 40 mg.
      • A higher proportion of patients in clinical trials reacted to first dosages of 20 mg compared to 5 or 10 mg.
      • It has not been established that treating more than four headaches on average in a 30-day period is safe.

• Oral:

  • Adolescents ≤17 years:

    • Limited data available; efficacy results variable; efficacy of oral sumatriptan was not established in five controlled trials in adolescent patients; frequency of adverse events was dose-related and age-dependent (ie, younger patients reported more adverse events)

  • Adolescents ≥18 years:

    • Initial single dose: 25 mg, 50 mg, or 100 mg.
    • If adequate pain relief not achieved at 2 hours, a second dose may be given.
    • Results from clinical trials show that initial doses of 50 mg and 100 mg are more effective than doses of 25 mg, and that 100 mg doses may have increased potential for side effects and are not superior to 50 mg.
    • Maximum daily dose (cumulative 24 hours): 200 mg total dose/24 hours.
    • It has not been shown safe to cure more than four headaches on average in a 30-day period.

• SubQ:

  • Children ≥6 years and Adolescents ≤17 years:

    • 3 to 6 mg single dose. An open-labeled prospective trial of 17 children 6 to 16 years with juvenile migraine used SubQ doses of 6 mg in 15 patients weighing 30 to 70 kg, and 3 mg/dose in two children weighing 22 kg and 30 kg.
    • Another open-label prospective trial in 50 consecutive children (ages 6 to 18 years) with severe migraine used SubQ doses of 0.06 mg/kg/dose.
    • Relief was reported as good/excellent in 84% of the patients; 16% reported fair to poor relief; additional studies are needed.

  • Adolescents ≥18 years:

    • Imitrex, Sumavel: Initial: 6 mg;
    • if adverse effects not tolerated use lower doses:
      • Imitrex: 1 to 5 mg or
      • Sumavel: 4 mg.
    • if required repeat ≥1 hour after starting dose;
    • maximum dose: 6 mg/dose;
    • The total maximum 24-hour dose: 12 mg (two 6 mg injections).
    • Controlled clinical trials do not show benefit of a second 6 mg dose in non responders.
    • Zembrace: Initial: 3 mg; after 1 hour may repeat dose if needed up to 4 injections separated by at least 1 hour;
    • may also administer following the dose of another sumatriptan product if separated by at least 1 hour; total maximum 24-hour dose: 12 mg.

Sumatriptan Pregnancy Risk Category: C

• A study that used healthy, full-term human placentas was conducted and found that only a small amount of sumatriptan crossed the placenta.
• Data from September 2012 on 617 pregnancies (including 7 that were also exposed to Naratriptan) was collected.
• Sumatriptan exposure in the first trimester was associated with a 4.2% risk of major birth defects. There was no consistent pattern of birth defect cases.
• A study of data from the Swedish Medical Birth Register between 1995 and 2008 revealed that 5-HT1B/1D anabolic exposure led to pregnancy outcomes.
• Major congenital abnormalities were not increased by the first trimester sumatriptan administration (2.229 mg).
• The Norwegian pregnancy registry study's data revealed no elevated risk of significant congenital abnormalities.
• The study involved 415 women who had used sumatriptan in the first trimester between 2004 and 2007.
• Sumatriptan might be used to treat cluster headaches in pregnancy.
• For the initial treatment for migraines in pregnancy, other agents are preferable. However, sumatriptan can be used if first-line drugs fail to work.

Sumatriptan can be used during breastfeeding

• Breast milk contains sumatriptan.
• The mean relative infant dose of sumatriptan (RID) was 3.5% according to a study comparing it to a maternal weight-adjusted dose of 6mg.
• When the RID is less than 10%, breastfeeding is generally acceptable.
• Sumatriptan's RID was calculated with a milk concentration of 87.2 mg/L (range 61.9- 112.5 mcg/L).
• The milk concentration was determined after the maternal administration of sumatriptan 6mg SubQ to 5 women (mean length of lactation 22.2 week). Milk concentrations were measured over 8 hour.
• Breast milk had a median half-life of 2.2 hours. Maximum milk concentrations were between 1.7 to 3.5 after maternal dose.
• Manufacturers recommend that you refrain from breastfeeding for 12 hours after oral, subcutaneous or intramuscular administration.
• According to some sources, breastfeeding can be continued if necessary.

Dose in Kidney Disease:

• The manufacturer's label does not disclose any dose modifications (has not been studied).
• Therefore, no dosage modification is anticipated because inactive drugs are extensively metabolised.

Sumatriptan (Imitrex) Dose in Liver disease:

• Hepatic impairments mild to moderate:

  • Oral:
    • Liver disease can increase the bioavailability and bioavailability oral sumatriptan.
    • Do not exceed 50 mg if treatment is required.
  • Intranasal
    • The manufacturer's label does not provide any dosage adjustments (has not been tested).
    • Due to the extensive metabolism of inactive agents, however, there is no need to adjust the dosage.
  • SubQ
    • There is no need to adjust the dosage.

• Severe hepatic impairment

  • In severe hepatic impairment, contraindicated formulations for oral, subcutaneous, and intranasal (Imitrex, Zembrace injection) are
  • Sumavel should not be used in severe hepatic dysfunction.

• Ophthalmoplegic migraine

Warnings and precautions

• Anaphylactic and anaphylactoid reactions

  • Anaphylactic, anaphylactoid and hypersensitivity reactions (including angioedema), have been observed.

• Cardiac events

  • With 5-HT agonist administration, some of these events occurred within hours.
  • If these side effects persist, discontinue sumatriptan.
  • Patients experiencing chest pain/pressure/tightness, or other symptoms that suggest angina should be examined for coronary artery disease and Prinzmetal angina. If dosing is recommenced and the same symptoms recur after dosing, ECG monitoring may be recommended.

• Cerebrovascular events

  • 5-HT agonists have been linked to stroke and subarachnoid hemorhage (may prove fatal).
  • If a cerebrovascular emergency occurs, discontinue use.

• Depression in the CNS:

  • CNS depression may result in weakness, sleepiness, or vertigo. Both the body and the mind may be impacted by this. Patients should use caution when performing jobs that call for mental clarity (eg driving or operating machinery).

• High blood pressure

  • Patients with no history of hypertension have rarely experienced significant elevations in blood pressure.
  • Patients with uncontrolled hypertension are contraindicated

• Ocular effects

  • Use of 5-HT agonist has been associated with partial and permanent vision loss, as well as temporary and permanent blindness.

• Serotonin syndrome

  • Serotonin syndrome can occur when 5-HT agonists are combined with other serotonergic medications. Symptoms (eg., diarrhea, hyperreflexia and hyperthermia), incoordination, mental state changes, nausea, tachycardia and vomiting) usually occur within minutes to hours of starting/dosing up on a serotonergic medication.
  • If you suspect serotonin syndrome, discontinue use.

• Vasospasm-related events

  • Five-HT agonists have been shown to cause peripheral vascular ischemia, GI vascular ischemia infarction and infarction, as well as Raynaud syndrome.

• Coronary artery disease

  • Before starting treatment, perform a cardiovascular assessment in patients with 5-HT agonists-naive CAD risk factors (eg, hypertension and hypercholesterolemia; smokers, obese, diabetes, strong family history, menopause, males >40 years old).
  • Patients suspected of having CAD should undergo a cardiovascular evaluation. If the cardiovascular evaluation is positive, first dose should be administered in the office of a health care provider (eg monitoring).
  • These patients should have their cardiovascular health monitored regularly during long-term intermittent use.

• Hepatic impairment

  • When treating patients who have mild to moderate hepatic impairment, sumatriptan oral formulations should be used cautiously.
  • Sumatriptan is administered orally through hepatic first pass metabolism. Patients with hepatic impairment will need to adjust the dose in oral preparation. However, it is not necessary to adjust the dose via Non-oral routes (intranasal, intracutaneous) for patients with hepatic impairment.
  • In severe hepatic impairment, Sumavel should not be used.

• Seizure disorders

  • Individuals who have seizure disorders or who have low seizure thresholds need to exercise caution. Even in patients who had never had seizures, sumatriptan-treated patients had experienced seizures.

Sumatriptan: Drug Interaction

Risk Factor C (Monitor therapy)
Antiemetics (5HT3 Antagonists)	Could make serotonin modulators' serotonergic effects stronger. Serotonin syndrome might occur from this.
Antipsychotic Agents	Serotonin modulators might make antipsychotic drugs more harmful or toxic. Serotonin modulators, in particular, may enhance dopamine blockade, potentially raising the risk for neuroleptic malignant syndrome. Serotonin modulators' serotonergic effects may be strengthened by antipsychotic drugs. Serotonin syndrome might occur from this.
Droxidopa	Droxidopa's hypertensive action may be enhanced by serotonin 5-HT1D receptor antagonists.
Metaxalone	Could make serotonin modulators' serotonergic effects stronger. Serotonin syndrome might occur from this.
Methylphenidate	Serotonin modulators' harmful or toxic effects could be exacerbated. In particular, there may be an increased risk of serotonin syndrome or serotonin poisoning.
Metoclopramide	Serotonin modulators may intensify Metoclopramide's harmful or hazardous effects. These could appear as signs of neuroleptic malignant syndrome or serotonin syndrome.
Opioid Agonists	Could make serotonin modulators' serotonergic effects stronger. Serotonin syndrome might occur from this.
Serotonin Modulators	The negative or hazardous effects of other serotonin modulators might be increased. Serotonin syndrome may start to develop. Nicergoline and Tedizolid are exceptions.
TraMADol	Serotonin modulators may intensify TraMADol's harmful or hazardous effects. Seizures may become more likely. The serotonergic impact of serotonin modulators may be enhanced by TraMADol. Serotonin syndrome might occur from this.
Risk Factor X (Avoid combination)
Dapoxetine	Serotonin modulators' harmful or toxic effects could be exacerbated.
Ergot Derivatives	May enhance serotonin 5-HT1D receptor antagonists' ability to constrict blood vessels. The vasoconstrictive effects of ergot derivatives may be enhanced by serotonin 5-HT1D receptor antagonists. Exceptions: Nicergoline.
Methylene Blue	Could make serotonin modulators' serotonergic effects stronger. Serotonin syndrome might occur from this.
Monoamine Oxidase Inhibitors	May slow down the metabolism of substances that block serotonin 5-HT1D receptors. Management: Naratriptan, eletriptan, or frovatriptan may be suitable 5-HT1D agonists to use if MAO inhibitor medication is necessary.
Serotonin 5-HT1D Receptor Agonists	May intensify SUMAtriptan's harmful or negative effects.

Monitoring parameters:

1. Headache severity
2. Blood pressure
3. Symptoms and signs that point to angina. Before beginning 5-HT agonist-naive people with various cardiovascular risk factors, conduct a cardiovascular assessment (eg increased age, diabetes, smoking, obesity or strong family history of CAD).
4. Several cardiovascular risk factors should be considered by patients when monitoring their ECG.
