Key Takeaways

  • Cold sore diagnosis is done by your doctor on examining the affected area
  • Cold sore treatment includes OTC medicines, creams, and home remedies
  • For effective results, take cold sore medication after seeing the initial signs

Cold sores are blisters filled with fluid caused by exposure to herpes simplex virus, which is highly contagious and common. Cold sore treatment consists of various options such as oral medication, ointments, and at-home remedies.

A cold sore disappears within 1-2 weeks but getting treatment can help shorten the duration. Cold sore treatment can also help relieve the discomfort and pain caused by them. Cold sore reoccurs because once the virus enters your body, it stays in your system for the rest of your life [1]. It stays dormant and becomes active once you come in contact with the trigger.

If you have previously had a cold sore, diagnosis for recurring cases is easy as you may already know the initial signs. Common signs of cold sores are fever, headache, muscle aches, painful gums, sore throat, and more. You should especially consult a doctor if cold sores do not heal within 2 weeks or if you have a weakened immune system.

Read on to know more about cold sore diagnosis and cold sore treatment.

Cold Sore Diagnosis 

Your doctor can usually make a cold sore diagnosis by examining the affected the area. They may also take a swab sample of the cold sore fluid to check for herpes simplex virus. Apart from the swab test, your doctor may also advise a blood test if you have weakened immune system.

Factors that can weaken your immune system include the following: 

  • Medicines after an organ transplant 
  • Certain cancers and cancer treatments

  • Severe symptoms 
  • Swollen gums 
  • Delay in healing 
  • Other symptoms of concern

Cold Sore Treatment 

Most outbreaks of cold sore disappear within 2 weeks and don’t require any treatment. But some OTC medication and ointments can help shorten the duration and relieve any pain and discomfort caused by it. The best cold sore treatment is to get necessary cold sore medication and ointment at an early stage.

Common cold sore medication and creams that your doctor may prescribe may include the following: 

1. OTC Creams 

This cold sore medication can be bought without prescriptions, and you can apply it directly on the affected area. You should use these when you notice the initial signs of itching or tingling. This can help prevent the cold sore from developing.

2. Oral Medicine 

This is generally an antiviral medicine prescribed by the doctor that you can take orally.

Triggers for Cold Sore

3. IV Antiviral Medicine 

This cold sore treatment is used when other treatment methods are not working. Your doctor may prescribe antiviral medicine administered through an IV. Your doctor will closely monitor you throughout the treatment to notice the effects of the treatment.

Apart from these, you can also try some at-home remedies that can help with cold sore treatment. Common home remedies are given below [2]:

4. Using Creams and Lip Balms 

Make sure the cream and lip balm you use has zinc oxide and sunblock. This can help protect you from sun and is also one of the common cold sore on lip treatment methods.

5. Applying a Compress 

Use a damp and cold cloth and apply it on the affected area. This can help reduce redness. It can also help promote healing by removing the crusting.

6. Taking Rest and Painkillers 

If you also have fever with a painful cold sore, try OTC pain relivers. Creams that contain benzocaine and lidocaine can offer you some relief from the pain.

If you have recurring cold sores, avoid common triggers and take the necessary precautions. Some preventive tips that can help with cold sores are:

  • Avoid any intimate contact with someone who has cold sores 
  • Thoroughly wash your hands after applying the cream or touching the cold sore 
  • Wear a sun protective lip balm 
  • Take proper rest and stay healthy 
  • Drink fluids and eat soft, cool food
