Trudhesa unites a trusty drug with gentle delivery

Time-tested and long-lasting

The medication in Trudhesa is called DHE or, if you want to get technical, dihydroergotamine mesylate. It has been used by specialists and hospitals for years. DHE is known for working when nothing else will.

Words 'About 2 out of 3 people had pain relief at 2 hours'

The result from a previous study of DHE with nasal spray delivery showed
In 4 previous studies of people using DHE with an older nasal spray device, many had no pain or mild pain at 2 hours.
Study 1

About 2 out of 3 people had pain relief

Study 2

About half of people had pain relief

Studies 3 and 4

3 out of 10 people had pain relief

Today, DHE is together with advanced delivery technology and ready to provide relief on demand.

Precision Olfactory Delivery but you can call it POD®

POD is designed to gently deliver medication to the ideal place in your nose for rapid absorption into your circulation. And that place is the upper nasal space.

There’s nasal, and then there’s upper nasal

This area of the nose is rich in blood vessels, so medications can be quickly absorbed into your circulation.

It also means that the drug doesn't need to take the journey through your gastrointestinal (GI) tract before it can start to work.

What relief at the ready could mean for you

And what exploratory results from a 24-week study of the safety showed, where 4515 migraine attacks were treated with Trudhesa.

In some people, Trudhesa was:

9 out of 10 people who were pain free at 2 hours were still pain free at 48 hours*

Of all the migraine attacks treated, 85% didn’t require a second dose, and those who got relief with Trudhesa once, were likely to get relief again

Rates of pain freedom were the same whether people took Trudhesa within 2 hours or several hours into a migraine attack*

When people compared Trudhesa to their regular migraine medication, more than half said Trudhesa:

  • Worked faster
  • Lasted longer
  • Was more consistent
  • Got them back to normal activities quicker
  • Results were from a poststudy questionnaire, which asked 354 people with migraine to rate their experience with Trudhesa against their best usual care. The results were patient-reported and not validated.

How to Use

Serious or potentially life-threatening reductions in blood flow to the brain or extremities due to interactions between dihydroergotamine (the active ingredient in Trudhesa) and strong CYP3A4 inhibitors (such as protease inhibitors and macrolide antibiotics) have been reported rarely. As a result, these medications should not be taken together.
Trudhesa is used to treat an active migraine headache with or without aura in adults. Do not use Trudhesa to prevent migraine when you have no symptoms. It is not known if Trudhesa is safe and effective in children.
Do not use Trudhesa if you:
  • Have any disease affecting your heart, arteries, or blood circulation
  • Are taking certain anti-HIV medications known as protease inhibitors (such as ritonavir or nelfinavir)
  • Are taking a macrolide antibiotic such as clarithromycin or erythromycin
  • Are taking certain antifungals such as ketoconazole or itraconazole
  • Have taken certain medications such as triptans or ergot-type medications for the treatment or prevention of migraine within the last 24 hours
  • Have taken any medications that constrict your blood vessels or raise your blood pressure
  • Have severe liver or kidney disease
  • Are allergic to ergotamine or dihydroergotamine
Before taking Trudhesa, tell your doctor if:
  • You have high blood pressure, chest pain, shortness of breath, heart disease; or risk factors for heart disease (such as high blood pressure, high cholesterol, obesity, diabetes, smoking, strong family history of heart disease or you are postmenopausal, or male over 40); or problems with blood circulation in your arms, legs, fingers, or toes.
  • You have or had any disease of the liver or kidney.
  • You are taking any prescription or over-the-counter medications, including vitamins or herbal supplements.
  • You are pregnant, planning to become pregnant or are nursing, or have ever stopped medication due to an allergy or bad reaction.
  • This headache is different from your usual migraine attacks.

The use of Trudhesa should not exceed dosing guidelines and should not be used on a daily basis.

Serious cardiac (heart) events, including some that have been fatal, have occurred following the use of dihydroergotamine mesylate, particularly with dihydroergotamine for injection, but are extremely rare.
