What are treatment options to phlebitis?

Antiinflamatory meds. Treatment of a superficial phlebitis involves antiiflamatory medication and warm soaks.
Many Options. I assume you are talking about a superficial phlebitis of the legs. The best option is to wear graduated compression stockings, take and anti-inflammatory medication daily and use moist heat to the area. I do a lot of vein care and at times will start the patient on Prednisone and at times drain the clotted blood from the vein to speed up the healing process.
