I was not able to find anything to boost its damage, since the effect is applied separately from the shot, meaning that player damage boosting perks, chems etc. do not work on it.
In my experience, Syringer is a great stealth weapon. Get detected = Pax Syringe or Mind Cloud Syringe and sneak away or just right past the enemy. I had not encountered any organic enemy not to be affected by those two. Berserker Syringe is also fun (especially with Super Mutant Suiciders).
Paralyze and Endangerol can be good for companion-focused characters
