The Essential Guide to Migraine Treatments: Choosing Between Rescue and Preventative Therapies

Navigating the complexities of migraine treatment can be overwhelming, with various options categorized into two main types: rescue and preventative therapies. This guide aims to clarify these options, helping you make informed decisions about managing your migraine effectively.

Rescue Treatments: Immediate Symptom Management

Rescue medications, also known as abortive therapy, are taken at the onset of migraine symptoms to stop the headache in its tracks. Here's what you need to know about the common types:

1. Simple Analgesics: Drugs like Acetaminophen (Tylenol) and non-steroidal anti-inflammatory medications (NSAIDs) such as Ibuprofen (Advil) are the first line of defense. Opioids and opioid-like pain killers (e.g., Morphine, Oxycodone, Tramadol) are considered analgesics, however they are rarely used in headache rescue for two major concerns: 

   • A) They tend to mask rather than abort the headache, leading to a potential recurrence once the drug wears off—a phenomenon known as rebound headache.
   • B) Frequent use can lead to medication-overuse headache (MOH), a challenging condition to treat. Read more about MOH here.

2. Anti-emetics: Nausea is a predominant symptom of migraines, at times more debilitating than the headache itself. Anti-emetics not only relieve nausea but also impact brain centers that trigger migraines. Their utility extends beyond mere nausea treatment, making them a crucial component of rescue therapy even if the nausea is minimal.

3. Migraine-Specific Treatments: This category includes Triptans (e.g., Sumatriptan, Rizatriptan) and CGRP antagonists (e.g., Ubrogepant (Ubrelvy), Rimegepant (Nurtec)). These are not typical analgesics; they specifically target migraine mechanisms and are known for their effectiveness and favorable side effect profiles. While beneficial, it's important to note that even these specific treatments can lead to MOH if used excessively.

4. Dihydroergotamine (DHE): For severe cases that resist other treatments, DHE remains a potent option. It's one of the specialized services offered at facilities like Miami Headache & Pain Clinic due to its efficacy in managing resistant migraine attacks.

Preventative Therapy: Reducing Migraine Frequency and Severity

Preventative medications are used regularly to decrease the likelihood and impact of migraine attacks. The selection of a preventative treatment is based on several factors, including migraine type, attack frequency, and any co-existing medical conditions. The array of options includes:

• Anti-hypertensives
• Anti-depressants
• Anti-convulsants
• Botox (R)
• CGRP antagonists
• And many others

While the list of potential preventative therapies is extensive, a detailed discussion of each is beyond the scope of this article, though future discussions are planned.

Knowing the distinction between preventative and rescue therapy is important, because their efficacy should be judged accordingly. For example, if you have 3 migraine attacks a week, and a preventative therapy reduces that frequency to only 1 time a week, then this preventative therapy has worked, even if the remaining headache is still out-of-this-world-intense and disabling. Along the same lines, if you have 10 migraine attacks a month, but for each attack a single pill of triptan resolves the headache completely, then this rescue is effective, even if it has not reduced the frequency. Understanding this difference will allow you to know what the target is for each treatment, and add them to each other effectively to arrive to the best possible outcome in the quality of life.

Deciding on Preventative Therapy

The conventional wisdom suggests initiating preventative therapy when migraines occur more than four times a month. Here's why:

• Starting a daily medication regimen is a significant commitment, and many patients prefer not to embark on this path unless necessary.
• At lower attack frequencies, it's challenging to assess whether a medication is truly effective due to the natural variability in migraine occurrence. For example, if you had 1 attack a month before starting a preventative therapy. The following two months, you had no attacks at all, but then had 2 attacks the month after. Has the medication worked? or was that just an expected variation of the headache frequency? This ambiguity makes it difficult to judge if the treatment is worth continuing or not. On the other hand, if someone has a migraine 14 times a month, and then headache frequency drops to 4, then it is obvious that the treatment has worked.

Special Cases Where Preventative Therapy May Be Initiated Sooner

While the general rule applies to most, there are exceptions:

• Severe Debilitation: For patients whose migraines are so severe they require emergency care or hospital admissions, starting preventative therapy may be justified even if attacks are infrequent.
• Complex Symptoms: Patients experiencing severe neurological impairments with their migraines, such as paralysis or profound confusional states, may also benefit from early preventative treatment.
• Occupational Considerations: Individuals in critical roles where even one attack could be disastrous (e.g., pilots, surgeons) might start preventative therapy sooner. This also applies to those experiencing migraines with visual auras, who face significant risks if an aura occurs during critical tasks, such as schoolbus drivers.
• Special cases: Certain migraine headaches can be easy to anticipate, and hence one can pre-emptively attempt to treat them with a rescue therapy, effectively using the abortive therapy as a preventative measure. For example, a woman who has menstrual migraines may elect to use an abortive therapy (such as Ibuprofen or a triptan) each morning during her period, and hence minimizes the possibility of having a headache during that time. Another example is a patient who gets a migraine headache after sexual intercourse, and hence elects to use a rescue treatment just before intercourse.

Conclusion

Understanding the distinctions between rescue and preventative therapies—and when each is appropriate—is crucial for effective migraine management. This knowledge empowers patients to collaborate with their healthcare providers to tailor treatment plans that not only address the symptoms but also integrate seamlessly into their lifestyles, ultimately enhancing well-being and daily functioning.
