Salt is not a recommended treatment for cold sores due to its potential to cause pain, irritation, and delayed healing. While it may temporarily dry out the lesion, it can also damage the surrounding healthy tissue. Instead, better options for cold sore treatment include over-the-counter medications like docosanol (Abreva) which can be applied at the first sign of a cold sore, or prescription antivirals such as acyclovir (Zovirax), valacyclovir (Valtrex), or famciclovir (Famvir) 1. These medications work by targeting the herpes simplex virus that causes cold sores. For pain relief, consider using benzocaine or lidocaine products. Cold compresses can also help reduce pain and swelling. Cold sores typically heal on their own within 7-10 days, but these treatments can speed healing and reduce discomfort. If you experience frequent or severe outbreaks, consult a healthcare provider for prescription options.
Some key points to consider when treating cold sores include:
- The use of antiviral medications such as acyclovir, valacyclovir, or famciclovir to target the herpes simplex virus 1
- The application of over-the-counter medications like docosanol (Abreva) at the first sign of a cold sore
- The use of pain relief products such as benzocaine or lidocaine
- The application of cold compresses to reduce pain and swelling
- The importance of consulting a healthcare provider for prescription options if you experience frequent or severe outbreaks
It's also important to note that current research suggests that antiviral chemotherapeutic agents are the only approved drugs used to prevent the worst sequelae of recurrent outbreaks by herpes simplex viruses-1 and -2 2. Therefore, it's essential to prioritize these treatments over alternative methods like using salt to dry out cold sores.
