The most common adverse effect reported was nausea, which occurred in less than 5% of users, the company said.
Migraine headache pain is often described as an intense throbbing or pulsating pain in one area of the head. Additional symptoms include nausea and/or vomiting and sensitivity to light and sound. Approximately one third of individuals who suffer from migraine also experience aura shortly before the migraine. An aura can appear as flashing lights, zig-zag lines, or a temporary loss of vision. Migraines can often be triggered by various factors including stress, hormone changes, bright or flashing lights, lack of food or sleep and diet. Migraine is three times more common in women than in men and affects more than 10% of people worldwide.
In a study published last month, the drug showed greater rates of pain and symptom relief from migraine compared to a placebo, with more than 19% of participants given the drug reporting to be pain-free within two hours and nearly 40% relieved of the most bothersome symptoms linked to migraine, which include light and noise sensitivity. This is compared to roughly 12% and 28%, respectively, from the placebo. Nausea, sleepiness and dry mouth were the most commonly reported side effects.
Prior to treatment, patients involved in the studies reported moderate to severe migraine pain, with symptoms such as nausea and sensitivity to light and sound. Results showed that a high percentage of patients were able to gain relief from their migraine pain, some in as little as two hours after treatment. The most common side effect reported was nausea and dry mouth.
