 Ubrelvi quickly stops migraine in its tracks within two hours without worrying where you are. Most people had quick pain relief within two hours. Ubrelvi treats migraine attacks in adults and is not for prevention. It's available by prescription only. Do not take Ubrelvi with strong CYP3A4 inhibitors. Tell your healthcare provider about all the medicines you take. Most common side effects are nausea and tiredness. My hope is that by sharing my migraine story and the relief I get from Ubrelvi, it can help someone else.
