Migraine Pregnancy Information

Migraine Pregnancy Information

Migraine usually takes a back seat during pregnancy. The painkilling effects of pregnancy hormones are thought to be the cause of this.

During pregnancy, several different researchers have noticed a very strong tendency for migraine to resolve during the second and third trimesters. This can be as much as an 80% reduction.

Worsening of migraine can occur in early pregnancy, and may be associated with vomiting of pregnancy, and unfortunately about 50% of women with migraine will experience a return of migraine in the first month after delivery.

Treating Migraine when Pregnant

The main thing is that you have a good routine and look after yourself - old fashioned advice - remember that the following will help prevent migraine:

  1. A good sleep pattern
  2. Keep hydrated - a cup of water every hour while awake
  3. Regular exercise, like walking 2-3 miles three times per week
  4. Avoiding obesity, and keeping weight gain to a minimum (difficult when you are pregnant I accept)
  5. Stress avoidance

There is scientific evidence to back up these statements - the bottom line - the better you look after yourself physically and mentally the less migraine you are likely to experience.

Are Migraine Medications Safe in Pregnancy?

In any individual it is impossible to make a 100% accurate prediction about what will happen in the future following taking a medicine.

It is, however, possible to suggest levels of risk associated with certain medicines.

The following drugs are generally regarded as low risk for use in pregnancy:

  1. Acute treatments for a migraine attack
    • Anti-emetics:

    • Metoclopramide
    • Promethazine
    • Analgesics (painkillers)

    • Paracetamol / Acetaminophen
    • Aspirin
    • Ibuprofen

    A combination of an anti-emetic and analgesic and a good sleep will probably treat the vast majority of pregnancy migraine.

  2. Migraine Prevention
    • Propranolol
    • NB - may affect fetal blood flow,so there is some caution in use of propranolol.
    • Magnesium preparations
    • Amitryptiline

    These should be reserved for people with disabling, frequent attacks who find it difficult to get relief from the other treatments for a migraine attack.

Breastfeeding and Migraine

These are thought to be OK in lactation (breastfeeding), as they do not pass in high concentrations into breastmilk.

  1. Acute treatments for a migraine attack
    • Sumatriptan
    • Paracetamol
    • Promethazine

  2. Migraine Prevention while breastfeeding
    • Magnesium
    • Propranolol
    • Timolol
