6 ADVERSE REACTIONS The following serious adverse reactions are described below and elsewhere in the labeling: Hypersensitivity Reactions [see Warnings and Precautions (5.1) ] Constipation with Serious Complications [see Warnings and Precautions (5.2) ] Hypertension [see Warnings and Precautions (5.3) ] Raynaud's Phenomenon [see Warnings and Precautions (5.4) ] The most common adverse reactions in AIMOVIG clinical studies (occurring in at least 3% of treated patients and more often than placebo) are injection site reactions and constipation.

6.1 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 2537 patients with migraine who received at least one dose of AIMOVIG, representing 3040.2 patient-years of exposure.

Of these, 2271 patients were exposed to 70 mg or 140 mg once monthly for at least 6 months, 1305 patients were exposed for at least 12 months, and 216 patients were exposed through 5 years.

In placebo-controlled clinical studies (Studies 1, 2, and 3) of 2184 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 [see Clinical Studies (14) ] .

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).

, The rate of injection site reactions reported in Table 1 is with the prefilled syringe.

The most frequent injection site reactions were injection site pain, injection site erythema, and injection site pruritus.

6.2 Postmarketing Experience The following adverse reactions have been identified during postapproval use of AIMOVIG.

Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

Immune System Disorders: Hypersensitivity reactions, including rash, angioedema, and anaphylaxis [see Warnings and Precautions (5.1) ].

Gastrointestinal Disorders: Constipation with serious complications [see Warnings and Precautions (5.2) ] , oral mucosal ulceration .

Skin and Subcutaneous Tissue Disorders: Rash, alopecia.

Vascular Disorders: Hypertension [see Warnings and Precautions (5.3) ] , Raynaud's Phenomenon [see Warnings and Precautions (5.4) ].
