CGRP Inhibitors: Your Quick Guide to Migraine Relief

If you’ve ever counted the days between migraine attacks, you know how unpredictable they can be. CGRP inhibitors are a newer class of drugs that aim to stop those attacks before they even start. They’re not pills you take every day; most come as monthly or quarterly injections that target a specific protein linked to migraine pain.

How CGRP Inhibitors Work

CGRP stands for calcitonin gene‑related peptide, a tiny molecule that spreads across nerves during a migraine. When CGRP levels spike, blood vessels swell and you feel the throbbing headache. CGRP inhibitors are monoclonal antibodies designed to bind either the peptide itself or its receptor, blocking the signal that leads to pain.

Because they’re large proteins, these drugs can’t be swallowed – they need to be injected under the skin (subcutaneously) or into a vein (intravenously). After the shot, the antibody hangs around in your bloodstream for weeks, keeping CGRP in check without daily dosing. Many people notice fewer attacks after just one month.

Choosing the Right CGRP Inhibitor

The market now offers four main options: erenumab (Aimovig), fremanezumab (Ajovy), galcanezumab (Emgality), and eptinezumab (Vyepti). All have similar effectiveness, but they differ in dosing schedules. Erenumab is a once‑monthly shot, fremanezumab can be given monthly or quarterly, galcanezumab is also monthly, while eptinezumab requires an infusion every three months.

Side effects are usually mild – think injection site redness, occasional constipation, or rare allergic reactions. Because these drugs suppress a specific pathway rather than the whole nervous system, they tend to have fewer typical migraine medication drawbacks like dizziness or nausea.

If you’re thinking about trying one, start by talking to your neurologist or headache specialist. They’ll review your attack frequency, other health conditions, and insurance coverage – cost can be a hurdle since many plans still treat these as specialty drugs.

When you get a prescription, the pharmacy will either ship pre‑filled syringes to your door or set up an infusion center for eptinezumab. Most patients learn to self‑inject after a short training session; the process feels like a tiny pinprick and takes under a minute.

Keep a migraine diary while you’re on treatment. Note any changes in attack length, severity, and triggers. This data helps your doctor decide whether the drug is working or if another CGRP inhibitor might fit better.

Bottom line: CGRP inhibitors give many chronic migraine sufferers a way out of endless daily meds. They target the root cause, work over weeks, and have a clean side‑effect profile for most users. If you’re tired of counting down to your next headache, ask your doctor if a CGRP inhibitor could be your next step.
