I'm assuming you are low level and with badly balanced stats, first fight any werewolf and throw him love potions each one increase your reputation by 25, when you reach 80 or more the enemy have more chances to tease than attack. If you're still dying, when facing the alpha werewolf throw him sleeping mist that will make him sleep for 3 turns, but if you attack him it will weak up, so instead use silver bombs, they deal more damage to werewolf and won't weak up.
