Vein Infections

Updated November 21, 2016

Veins can become inflamed and infected, which if left untreated can become a serious condition. If you suspect you have a vein infection, you will need antibiotics to treat the infection before it spreads. Veins carry blood around the body, so the infection can spread quickly and seriously.


Infections usually start out as inflammation of the vein just beneath the skin. The inflammation usually goes away in a few weeks, but the vein can become infected. This can happen if you have a drip inserted for long periods, or have a compromised immune system.


When a vein becomes infected, the area becomes increasingly painful and the pain spreads further, such as down a leg or arm. You may notice the limb becomes red and the redness spreads down the limb. You may also feel unwell and possibly have a temperature.


A vein infection is treated with antibiotics, which should stop it from spreading. If the infection has already spread or is severe, you may need to be admitted into a hospital to be given antibiotics intravenously.
