Tag: Cold Sores

Cold sores, also known as fever blisters, are caused by the herpes simplex virus (HSV-1). They typically appear as small, fluid-filled blisters on or around the lips, though they can also occur on the nose, chin, or cheeks. Cold sores are highly contagious and can be spread through close contact, such as kissing or sharing utensils. While they often heal on their own within a week or two, over-the-counter antiviral creams like docosanol (Abreva) or prescription medications like acyclovir (Zovirax) can help reduce symptoms and speed up healing when applied at the first sign of an outbreak. These types of medicines can be bought online without a prescription: Valtrex, Valacyclovir, Zovirax, Acyclovir, Famvir, Famciclovir.
