Based on this small sample, ivabradine appears to be a reasonable option for patients with POTS who have failed or are unable to tolerate other treatment options, however, but a randomized controlled trial in this population is needed.

The studies included in this review indicate that levetiracetam is well-tolerated and may be an alternative treatment option for episodic migraine prophylaxis. Additional clinical evidence is necessary to establish the efficacy of levetiracetam for the prophylactic treatment of chronic migraine.
