Does Aimovig (erenumab) cause side effects?
Aimovig (erenumab) is calcitonin gene-related peptide receptor (CGRP-R) antagonist used for the preventive treatment of migraine in adults. CGRP-R is a chemical produced by the body that acts on blood vessels in the brain which are believed to be responsible for the development of migraines.
Aimovig reduces the number of monthly migraine attacks by blocking CGRP-R receptors on blood vessels.
Common side effects of Aimovig include
Less common side effects of Aimovig include
Drug interactions of Aimovig include have not been identified. Aimovig does not affect the breakdown of other drugs. Aimovig did not interact with sumatriptan or an oral contraceptive in laboratory studies.
The use of Aimovig during pregnancy has not been properly studied. It is not known whether Aimovig can affect the developing baby or the birthing process.
What are the important side effects of Aimovig (erenumab)?
The most common side effect of erenumab are reactions to the injection site, for example, injection site:
Less common side effects include:
The needle shield within the white cap of the erenumab prefilled autoinjector and gray needle cap of the erenumab prefilled syringe contains dry natural rubber, which may cause allergic reactions in people who are sensitive to latex.
There are no warnings for erenumab.

Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.
- The safety of Aimovig has been evaluated in 2,537 patients with migraine who received at least one dose of Aimovig, representing 2,310 patient-years of exposure.
- Of these, 2,057 patients were exposed to 70 mg or 140 mg once monthly for at least 6 months, 1,198 patients were exposed for at least 12 months, and 287 patients were exposed for at least 18 months.
- In placebo-controlled clinical studies (Studies 1, 2, and 3) of 2,184 patients, 787 patients received at least one dose of Aimovig 70 mg once monthly, 507 patients received at least one dose of Aimovig 140 mg once monthly, and 890 patients received placebo during 3 months or 6 months of double-blind treatment.
- Approximately 84% were female, 91% were white, and the mean age was 42 years at study entry.
- The most common adverse reactions (incidence ≥ 3% and more often than placebo) in the migraine studies were injection site reactions and constipation.
- Table 1 summarizes the adverse reactions that occurred during the first 3 months in the migraine studies (Studies 1, 2, and 3).
Table 1: Adverse Reactions Occurring with an Incidence
of at Least 2% for Either Dose of Aimovig and at Least 2% Greater than Placebo
During the First 3 Months in Studies 1, 2, and 3
|Adverse Reaction||Aimovig 70 mg Once Monthly
N = 787 %
|Aimovig 140 mg Once Monthly
N = 507 %
N = 890 %
|Injection site reactionsa||6||5||3|
|Cramps, muscle spasms||< 1||2||< 1|
|aInjection site reactions include multiple adverse reactions related terms, such as injection site pain and injection site erythema.|
- In Studies 1, 2, and 3, 1.3% of patients treated with Aimovig discontinued double-blind treatment because of adverse events. The most frequent injection site reactions were injection site pain, injection site erythema, and injection site pruritus.
- As with all therapeutic proteins, there is potential for immunogenicity. The detection of antibody formation, including neutralizing antibodies, is highly dependent on the sensitivity and specificity of the assay.
- Additionally, the observed incidence of antibody (including neutralizing antibody) positivity in an assay may be influenced by several factors including assay methodology, sample handling, timing of sample collection, concomitant medications, and underlying disease.
- For these reasons, comparison of the incidence of antibodies to erenumab-aooe in the studies described below with the incidence of antibodies in other studies or to other products may be misleading.
- The immunogenicity of Aimovig has been evaluated using an immunoassay for the detection of binding anti-erenumab-aooe antibodies. For patients whose sera tested positive in the screening immunoassay, an in vitro biological assay was performed to detect neutralizing antibodies.
- In controlled studies with Aimovig, the incidence of anti-erenumab-aooe antibody development was 6.2% (48/778) in patients receiving Aimovig 70 mg once monthly (2 of whom had in vitro neutralizing activity) and 2.6% (13/504) in patients receiving Aimovig 140 mg once monthly (none of whom had in vitro neutralizing activity).
- The neutralizing anti-erenumab-aooe antibody positive rate may be underestimated because of limitations of the assay.
- Although these data do not demonstrate an impact of anti-erenumab-aooe antibody development on the efficacy or safety of Aimovig in these patients, the available data are too limited to make definitive conclusions.
Aimovig (erenumab) is calcitonin gene-related peptide receptor (CGRP-R) antagonist used for the preventive treatment of migraine in adults. Common side effects of Aimovig include injection site reactions such as pain, redness, and itching. Less common side effects of Aimovig include constipation and muscle cramps or spasms. The use of Aimovig during pregnancy has not been properly studied. There is no information about whether Aimovig is present in breast milk, its effects on the breastfed infant, or its effects on milk production.

Abdominal Migraines in Children and Adults
Migraine headache is a type of headache associated with a sensitivity to light, smells, or sounds, eye pain, severe pounding on one side of the head, and sometimes nausea and vomiting. The exact cause of migraine headaches is not known. Triggers for migraine headaches include certain foods, stress, hormonal changes, strong stimuli (loud noises), and oversleeping. Treatment guidelines for migraines include medicine, pain management, diet changes, avoiding foods that trigger migraines, staying hydrated, getting adequate sleep, and exercising regularly. Prevention of migraine triggers include getting regular exercise, drinking water daily, reducing stress, and avoiding trigger foods.
Migraines and Seizures (Symptoms, Auras, Medication)
Migraines are a type of headache and seizures are the main symptom of epilepsy. Migraine headaches and seizures are two different neurological problems that have similar signs, symptoms, and auras, for example, sensitivity to light (photophobia) and sound, irritability, nausea, and vomiting. Symptoms unique to migraine and migraine auras are water retention, problems sleeping, appetite changes, and talkativeness. Symptoms unique to seizure and seizures auras are depression, a feeling of heaviness, a feeling that a seizure is approaching, and depression. Many of the symptoms of migraine and seizures are the same, however, seizures do not cause migraines; however, people who have seizures are twice as likely to have migraines and vice-versa. People who have migraines are twice as likely to have seizures, and people with seizures are twice as likely to have migraines; however, one condition does not cause the other.
Migraine and Stroke
Migraine headache is a type of headache in which the exact cause is not known; however, they may be inherited, and certain foods and environmental factors can trigger and may contribute them. A stroke (brain attack) happens when a blood vessel in the brain leaks, bursts, or becomes blocked, which can be caused by many other health problems. Both migraines and strokes can can cause severe head pain (migraine pain usually is only on one side of the head). Migraine aura symptoms may mimic or feel like a stroke or mini-stroke (transient ischemic attack, TIA) because they have similar symptoms and signs like severe headache, numbness in the legs, feet, arms, hands, or face, nausea, vomiting, and dizziness. Other migraine aura symptoms include vision problems like flashing lights or blind spots in one eye. The main difference between migraine headache and stroke symptoms and signs is that a migraine headaches usually come on gradually while a stroke symptoms come on suddenly and unexpectedly.

Headaches are the most common reason why a person goes to the doctor or other healthcare professional for treatment. There are different types of headaches, for example, migraine, tension, and cluster headaches. The most common type of headache is tension headache. Migraine is much less common. There are few similarities between migraine and other headaches, for example, the severity of the pain can be the same, mild, moderate, or severe; and they can occur on one side or both sides of the head. However, there are many differences between migraine and other types of headaches. Migraine headaches also have different names, for example, migraine with aura and menstrual migraine. Symptoms of migraine that usually aren't experienced by a person with another type of headache include nausea, vomiting, worsens with mild exercise, debilitating pain, eye pain, throbbing head pain. Migraine trigger include light, mild exercise, strong smells, certain foods like red wine, aged cheese, smoked meats, artificial sweeteners, chocolate, alcohol, and dairy products, menstrual period, stress, oversleeping, and changes in barometric pressure. Untreated migraine attacks usually last from 4 to 72 hours, but may last for weeks. Most headaches resolve within 24-48 hours. Doctors don't know exactly what causes migraine headaches; however, other headaches like tension headaches have more specific triggers and causes. Additional tests usually are required to diagnose migraine from other types of headaches, diseases, or other medical problems. Most headaches can be treated and cured with home remedies like essential oils, massage, and over-the-counter pain medication like acetaminophen (Tylenol) and NSAIDs (nonsteroidal anti-inflammatory drugs) like naproxen (Aleve, Anaprox, Naprosyn) or ibuprofen (Advil, Midol, Motrin). Most headaches resolve with OTC and home remedy treatment, while your doctor may need to prescribe medication to treat your migraines. If you have the "worst headache of your life," seek medical care immediately.
