Maxalt Melt is the brand name for a form of rizatriptan. Maxalt Melts are used to treat migraines that occur with or without aura. One Maxalt Melt should be taken when the migraine starts to relieve the pain. This form of Maxalt is sometimes favoured as the tablet melts in the mouth rather than needing to be swallowed. Maxalt Melts do not prevent the migraine from occurring in the first place.
