Does emgality cause constipation?

Probably not. According to the research done, 1% of people taking Emgality complained of constipation, versus 0.6% of those taking placebo. So very rare in both groups, and not necessarily caused by the drug. https://www.emgality.com/hcp/safety Discuss with your doctor.

Emgality results in very rare constipation complications. Aimovig is implicated in not infrequent constipation adverse effects, sometimes rather severe, and is best avoided if there is a history of constipation. Emgality is far better tolerated.
