The FDA has approved Trudhesa (Impel Neuropharma), a new dihydroergotamine nasal spray product, for acute treatment of migraine with or without aura in adults. Another dihydroergotamine nasal spray (Migranal, and generics) has been available for many years for the same indication.

Lyme disease in the US is caused by the spirochete Borrelia burgdorferi, which is transmitted to humans by Ixodes scapularis (blacklegged [deer] tick) and I. pacificus (western blacklegged tick). Most cases of Lyme disease occur in late spring and early summer in northeastern and mid-Atlantic states, the upper Midwest, and in northern California. B. mayonii, which is also transmitted by I. scapularis, has been shown to cause a similar illness in the upper Midwest.

The FDA has approved zavegepant nasal spray (Zavzpret – Pfizer) for acute treatment of migraine with or without aura in adults. Zavzpret is the first nasal spray formulation of a calcitonin gene-related peptide (CGRP) receptor antagonist ("gepant") to become available in the US.

An oral nonopioid analgesic is often sufficient for acute treatment of mild to moderate migraine pain without severe nausea or vomiting. A triptan is the drug of choice for treatment of moderate to severe migraine in most patients without vascular disease. Treatment of pain when it is still mild to moderate in intensity improves headache response and reduces the risk of recurrence.
