Cold sores, also known as fever blisters, are a common viral infection caused by the herpes simplex virus (HSV-1). While they are not typically serious, cold sores can be uncomfortable and unsightly. If you’re dealing with a cold sore outbreak, there are several ways to manage and treat it effectively. Here are some tips on how you can manage and find relief from cold sores.

What are Cold Sores?

Cold sores, also known as fever blisters, are small, painful, fluid-filled blisters that typically appear on or around the lips, though they can occur on other areas of the face as well. They are caused by the herpes simplex virus (HSV), with the most common culprit being HSV-1 (herpes simplex virus type 1). 

Cold sores are primarily caused by HSV-1. Once you are infected with this virus, it can remain dormant in your body, typically in nerve cells near the base of the brain or in the trigeminal ganglia (a nerve cluster in the face). Various triggers, such as stress, illness, sun exposure, or hormonal changes, can reactivate the virus, leading to the development of cold sores. 

Cold sores are highly contagious and the virus can be spread through direct contact with a cold sore or with the fluid from the blisters. It can also be transmitted through activities like kissing, sharing utensils or personal items, and oral sex.

Cold sores often start with a tingling or itching sensation, followed by the appearance of small, painful, fluid-filled blisters. These blisters can break open, ooze fluid, and form a crust before healing. Cold sores can be accompanied by discomfort, burning, or pain in the affected area.

They typically last around 7 to 10 days. It’s important to note that cold sores can recur, as the virus remains in the body.

How to Manage Cold Sores in Singapore

While there is no cure for herpes simplex virus (HSV-1), cold sore outbreaks can be managed through oral and topical medications in order to reduce their severity and speed up the healing process, providing relief from pain and discomfort. Additionally, adopting preventive measures can help reduce the frequency of outbreaks and lower the risk of transmission to others.

One of the most popular and readily available treatments for cold sores is cold sore cream. You can find a variety of over-the-counter (OTC) creams and ointments in local pharmacies and convenience stores. Most of these contain benzocaine or zinc which can help alleviate pain and discomfort associated with cold sores.


However, in Singapore, you would need to consult with a pharmacist or obtain a prescription from a doctor for cold sore creams containing antiviral medications like acyclovir. They can help reduce the duration and intensity of cold sores when applied as soon as you notice the initial signs of an outbreak.

In some cases, especially if you experience frequent or severe cold sore outbreaks, a healthcare provider in Singapore can prescribe antiviral medications in pill form, such as acyclovir, valacyclovir, or famciclovir. These medications are more potent than OTC creams and are recommended for individuals with more persistent or severe cold sore issues.

To prevent secondary bacterial infections, keep the cold sore clean and dry. Gently wash the area with mild soap and water, and avoid picking or squeezing the sore.

Certain factors can trigger cold sore outbreaks, such as stress, exposure to sunlight, and a weakened immune system. Try to minimize these triggers to reduce the frequency of outbreaks.

Proper hydration and a balanced diet and regular exercise can help support your immune system and overall health, which may reduce the frequency and severity of cold sore outbreaks.

To prevent spreading the virus to others, avoid close contact, such as kissing, during an active outbreak. Herpes simplex is highly contagious.


Remember that while there is no cure for the herpes simplex virus, the right treatment and preventive measures can help you manage cold sores effectively and enjoy a better quality of life in Singapore. If you have questions or concerns about your cold sores, consult a healthcare professional for personalised guidance and treatment options.

Frequently Asked Questions


When should I go for STD screening?

You should consider screening if you have symptoms of a possible STD, if you have had a recent risky exposure (unprotected sex with a casual partner), or both.

Can I get STDs from oral sex?

Yes, you can. The common misconception is that oral sex is not considered ‘real’ sex and therfore has no risk but the opposite is true. Often oral sex is performed without protection and this is why infections such as chlamydia and gonorrhoea can pass on through oral sex.

Can STDs be cured?

Thankfully the majority can be cured but there are some such as Herpes and HIV that can be treated but not cured. This is why prevention is better than cure and ensuring safe sex goes a long way to reduce your risks.
