How to Get Rid of Cold Sores Fast: Tips & Treatments

Cold sores are small, painful blisters caused by the herpes simplex virus (HSV-1). While they can’t be cured overnight, acting early can help you get rid of cold sores faster, reduce discomfort, and lower the chance of future outbreaks. This guide will help you understand how to get rid of cold sores quick, including treatments, home remedies, and prevention tips. 

What Causes Cold Sores 

Cold sores are caused by the herpes simplex virus type 1 (HSV-1). The virus is highly contagious and spreads through direct contact with an infected person's skin or saliva. Common triggers include: 

• Stress: Physical or emotional stress can weaken the immune system, making it easier for the virus to reactivate. 

• Illness: Colds, flu, or any illness that weakens the immune system can trigger cold sores. 

• Sun exposure: Prolonged exposure to sunlight can trigger an outbreak.

• Hormonal changes: Hormonal changes, such as those during menstruation, can also trigger cold sores [1][2]. 
  

Stages of a Cold Sore

After a cold sore is triggered, it usually develops in stages. Understanding these stages can help you act quickly and manage symptoms more effectively.

• Tingling stage: itching or burning before the sore appears
• Blister stage: small fluid-filled blisters form
• Weeping stage: blisters burst and ooze
• Crusting stage: scab forms
• Healing stage: skin repairs and scab falls off

How to Get Rid of a Cold Sore in 24 Hours

While it's difficult to get rid of a cold sore in 24 hours, starting treatment as soon as you notice symptoms (at the tingling stage) can significantly reduce the duration [2]. 

Here’s what to do in the first 24 hours of a cold sore, when you notice the “tingling” stage

1. Start antiviral treatment immediately if prescribed or use an OTC antiviral cream.
2. Avoid touching the area, which can spread the virus or worsen irritation.
3. Apply a cold compress for short periods to reduce swelling and pain.
4. Skip lip products or makeup on the affected area.
5. Support your immune system with rest, fluids, and balanced meals.

No treatment can kill cold sores instantly, but certain antiviral medications and topical treatments can help speed up the healing process [1][2]. 

Antiviral medications 

• Prescription antivirals: Medications such as acyclovir, valacyclovir, famciclovir, and penciclovir can help cold sores heal faster. These are available in oral form and as topical creams. It's important to start these treatments as soon as you notice symptoms for the best results [2]. 

• Over-the-counter options: Docosanol (Abreva) is a common OTC antiviral cream that can be applied to the affected area to potentially reduce healing time [2]. 

Topical treatments 

• Anaesthetic creams: Products containing lidocaine or benzocaine can help relieve pain. Some creams with benzyl alcohol may also promote faster healing [1][3]. 

• Cold compresses: Applying a cold, damp washcloth or ice (wrapped in a cloth) can numb pain and reduce swelling [1][3]. 

Home Remedies for Cold Sores

Several home remedies can help speed up the healing process and provide relief from cold sore symptoms. 

Essential oils and natural products 

• Tea tree oil, peppermint oil, lemon balm, and kanuka honey: These have been shown to help cold sores heal more quickly [3]. 

Cold sore supplements 

• Lysine: Lysine supplements, available in cream or capsule form, may help reduce the frequency and severity of outbreaks [3]. 

Vitamins for cold sores

• Vitamin C and E: Vitamin C may inactivate the herpes simplex virus, while vitamin E can help heal cold sores [3]. 

How long do cold sores last? 

Most cold sores heal on their own within 10 days (about 1 and a half weeks). Immediate cold sore treatments and home remedies can help speed up this process [1][2]. 

Prevention tips for cold sores 

Preventing cold sores from appearing in the first place is the best approach. Here are some tips to help you avoid outbreaks: 

Identify and avoid triggers 

• Sun protection: Use lip balm with SPF to prevent sun-triggered outbreaks [3][4]. 

• Avoid triggers: Stress, illness, and sun exposure can trigger outbreaks. Managing these factors can help prevent cold sores [3][4]. 

Lifestyle adjustments 

• Healthy diet: Consume a nutrient-dense diet to support immune function. 

• Adequate sleep: Ensure you get enough rest to help your body fend off outbreaks [7]. 

Medical interventions 

• Antiviral medications: For those with frequent outbreaks, doctors may prescribe antiviral medications. These can be taken short-term or long-term to prevent outbreaks [6][8]. 

• Lysine supplements: Taking lysine orally using lysine cream may help reduce the frequency of outbreaks. 

General precautions 

• Hygiene practices: Avoid touching the cold sore to prevent spreading the virus. Wash hands frequently and avoid sharing personal items like towels or utensils [8]. 

When to seek medical advice 

Most cold sores heal on their own within 10 days (about 1 and a half weeks), but there are situations where you should seek medical advice: 

• If you have frequent or severe outbreaks
• If the cold sore doesn't heal within two weeks
• If you have a weakened immune system
• If the cold sore spreads to other parts of your body [4] 

Cold sores can be a pain, but with the right treatments and preventive measures, you can reduce their impact and speed up the healing process. By understanding the causes, applying immediate treatments, using home remedies, and taking preventive steps, you can manage cold sores effectively and quickly.
