- Not effective for tension headache
Ergotamide tartrate
Ergotamide tartrate has high incidence of ADRs (2)

- Drowsiness (so have to limit use at work)
Overuse of ergotamide for acute migraine can cause (2)
- Rebound H/A
- 'ergotamide h/a'
Has a poor benefit/risk ratio --> there are better drugs for acute migraine

- Beta blocker
- Erythromycin
- Troleandomycin
- Derivative of ergotamine
- Available SC, IM, IV or nasal sprary
Dihydroergotamine
For acute migraine
- Less vasoconstrictive than ergotamine --> less likely to cause HTN
Dihydroergotamine
Causes less N/V and HTN than ergotamine
Dihydroergotamine
For acute migraine
- Little or no risk of rebound h/a
- ADRs - diarrhea + muscle cramps
Dihydroergotamine
Dihydroergotamine ADRs
