Notes
Unlike past Elder Scrolls games, in Skyrim there is no Cure Paralysis effect.
Finding merchants that sell items with this effect for disenchantment purposes is only possible when you are level 22 or higher.
The name of the alchemical version of this effect is actually "Paralysis" instead of "Paralyze".
Paralyze does not cause any direct damage to targets. However, because of the ragdoll effect, the victim might instead tumble off a cliff and receive fall damage, potentially killing them. 

If you have unlocked the Deep Freeze perk, a Deep Freeze Paralyze effect is added to all Frost Damage spells. This effect, however, is affected by any Alteration modifiers, such as the perk Stability.
Enemies fall over when paralyzed and take a moment to get back up. Even a one second Paralysis effect might disable them for several seconds, which might make it worth creating an enchantment with more charges rather than a greater duration. Also, while they are getting back up, the enemy will be completely vulnerable to pickpocketing, allowing you to take any item even if you have a 0% chance of stealing it.
Creatures that are immune to paralysis include: atronachs, automatons, chaurus hunters , dragons, dragon priests, gargoyles , ghosts, horses, ice wraiths, Karstaag , magic anomalies, mammoths, all varieties of mounted riekling , seekers , skeletons, vampire lords , werewolves, wisps, and wispmothers.
Named NPCs that are specifically immune to paralysis include: all the hostages during With Friends Like These, all Souls , Astrid, Ildari Sarothril , Jiub , Miraak , and the Ebony Warrior . 
Targets that are immune to paralysis may still be staggered.
Followers equipped with bows may have a difficult time hitting targets that are paralyzed because their AI doesn't know how to adjust their aim downwards.

Leaving and returning to the area makes the body lootable again.
