Ergot Alkaloids
The advantage of ergot alkaloids in some patients is a longer half life time and a lower recurrence rate. Therefore, these substances should be restricted to patients with very long migraine attacks or with regular recurrence. The only compound with sufficient evidence of efficacy is ergotamine tartrate 2 mg (oral or suppositories).

Migraine Prophylaxis
There is no commonly accepted indication for starting a prophylactic treatment. In the view of the Task Force, prophylactic drug treatment of migraine should be considered and discussed with the patient when
- The quality of life, business duties, or school attendance are severely impaired
- Frequency of attacks per month is two or higher
- Migraine attacks do not respond to acute drug treatment
- Frequent, very long, or uncomfortable auras occur

Migraine in Pregnancy
If migraine occurs during pregnancy, only paracetamol is allowed during the whole period. Non-steroidal anti-inflammatory drugs (NSAIDs) can be given in the second trimester. These recommendations are based on the advices of the regulatory authorities in most European countries. There might be differences in some respect between different countries (in particular, NSAIDs might be allowed in the first trimester).
For migraine prophylaxis, only magnesium and metoprolol are recommended during pregnancy (level B recommendation).
Definitions:
Evidence Classification Scheme for a Therapeutic Intervention
Class I: An adequately powered prospective, randomized, controlled clinical trial with masked outcome assessment in a representative population or an adequately powered systematic review of prospective randomized controlled clinical trials with masked outcome assessment in representative populations. The following are required:
- Randomization concealment
- Primary outcome(s) is/are clearly defined
- Exclusion/inclusion criteria are clearly defined
- Adequate accounting for dropouts and crossovers with numbers sufficiently low to have minimal potential for bias
- Relevant baseline characteristics are presented and substantially equivalent among treatment groups or there is appropriate statistical adjustment for differences
Class II: Prospective matched-group cohort study in a representative population with masked outcome assessment that meets a–e above or a randomized, controlled trial in a representative population that lacks one criteria a–e
Class III: All other controlled trials (including well-defined natural history controls or patients serving as own controls) in a representative population, where outcome assessment is independent of patient treatment
Class IV: Evidence from uncontrolled studies, case series, case reports, or expert opinion
Rating of Recommendations
Level A rating (established as effective, ineffective, or harmful) requires at least one convincing class I study or at least two consistent, convincing class II studies.
Level B rating (probably effective, ineffective, or harmful) requires at least one convincing class II study or overwhelming class III evidence.
Level C rating (possibly effective, ineffective, or harmful) requires at least two convincing class III studies.
