What are cold sores
Cold sores, also known as fever blisters, are small, painful blisters that typically appear on or around the lips, although they can also occur on the nose or inside the mouth.
They are caused by the herpes simplex virus (HSV-1), which is highly contagious and can be transmitted through direct contact with an active sore or through contact with bodily fluids such as saliva.
Cold sores typically start as small red bumps that develop into fluid-filled blisters that can burst and form crusts. They can be itchy or painful and can take anywhere from a few days to a couple of weeks to heal. They can also be accompanied by other symptoms such as fever, swollen lymph nodes, and general feelings of being unwell.
Once a person is infected with the herpes simplex virus, it can remain dormant in the body and reactivate later, causing cold sores to reoccur. There is no cure for the herpes simplex virus, but antiviral medications can be prescribed to help reduce the frequency and severity of outbreaks. Over-the-counter creams and ointments can also be used to help relieve pain and itching associated with cold sores.
It’s important to keep in mind that while the virus cannot be cured, it can be controlled and the symptoms can be managed by taking medication, preventing infection in others and taking steps to limit the severity and frequency of outbreaks.
What causes cold sores?
Cold sores are caused by the herpes simplex virus (HSV-1), which is a highly contagious virus. The virus is transmitted through direct contact with an active sore or through contact with bodily fluids such as saliva. This means that cold sores can be transmitted through kissing, sharing eating utensils, or even through close contact with someone who has an active sore.
Once a person is infected with the virus, it can remain dormant in the body and reactivate later, causing cold sores to reoccur. Certain triggers can cause the virus to reactivate, including stress, sun exposure, fever, colds, or other viral infections.
In addition to external factors like sun exposure and stress, some people may be more susceptible to cold sores due to their immune systems. Some people may have a genetic predisposition to cold sores and may be more prone to outbreaks.
It’s important to note that it’s not possible to catch cold sores from a toilet seat or any other inanimate object. Cold sores are caused by a virus, which can only be passed from person to person through direct contact.
Acid Reflux symptoms
There are several treatment options that a pharmacist may recommend for treating cold sores. These include
Antiviral creams:
These creams, such as acyclovir, or docosanol, can be applied to the affected area to help reduce the duration and severity of outbreaks. They work by stopping the virus from multiplying and may be more effective if applied at the first sign of a cold sore.
Oral antiviral medications:
In some cases, a pharmacist may recommend an oral antiviral medication, such as valacyclovir or famciclovir. These medications can be prescribed to help reduce the frequency and severity of outbreaks.
Lip balms:
Some lip balms or lip protectants contain ingredients such as sunscreen that may help reduce the risk of sun-induced outbreaks.
Cold sore patches:
These are adhesive patches that can be applied over a cold sore to help protect it and promote healing.
Pain relievers:
OTC pain relievers such as ibuprofen or acetaminophen can be used to help relieve pain and discomfort associated with cold sores.
It’s important to note that some OTC products may not be suitable for certain people, such as children, pregnant or breastfeeding women, or people with certain medical conditions. It’s always a good idea to check with a pharmacist or a doctor before using any OTC product for the first time.
Pharmacists can also give advice on preventive measures that can help to reduce the frequency of cold sore outbreaks, including avoiding triggers such as stress, sun exposure and colds, maintaining a healthy lifestyle, and practicing good hygiene.
Complications of cold sores
While cold sores are generally considered a minor and common condition, in some cases, complications can occur. Some potential complications of cold sores include
Eye infections:
Cold sores can spread to the eyes, which can cause serious infections, such as keratitis (inflammation of the cornea), or even blindness.
Skin infections:
Cold sores can also spread to the skin around the lips, leading to a bacterial infection. This can cause redness, pain, and pus-filled blisters.
Brain infections:
In rare cases, the herpes simplex virus can spread to the brain, leading to conditions such as encephalitis (inflammation of the brain) or meningitis (inflammation of the membranes surrounding the brain and spinal cord).
Neonatal herpes:
In newborns, cold sores can be life-threatening. If a woman has a cold sore and gives birth, there is a risk that the virus will spread to the baby during delivery. This can cause severe infections, brain damage, and even death.
Immune system problems:
Cold sores can be especially severe for people with weakened immune systems, such as people with HIV/AIDS or cancer, or people who are taking medications that suppress the immune system.
While cold sores are typically a minor and common condition, they can be serious in some cases, especially in people with weakened immune systems. If you are experiencing frequent, severe, or unusual cold sores, or if your cold sores are not responding to treatment, it’s important to seek medical attention.
Preventing infection for cold sores
There are several steps you can take to help prevent cold sore outbreaks or to reduce the risk of spreading the virus to others
- Practice good hygiene: This means washing your hands frequently, especially after touching an active cold sore. It’s also important to avoid sharing eating utensils, towels, or other personal items with someone who has a cold sore.
- Avoid physical contact: It’s best to avoid close physical contact with someone who has an active cold sore, especially kissing or other forms of contact that involve the mouth or face.
- Use sunscreen: Sun exposure can trigger cold sore outbreaks, so it’s important to use a lip balm or lip protectant that contains sunscreen to help protect your lips.
- Avoid triggers: Identify and try to avoid things that trigger cold sore outbreaks, such as stress, sun exposure, colds, and other viral infections.
- Keep the affected area clean and dry: Keeping the affected area clean and dry can help speed up healing and prevent secondary bacterial infections.
- Using antiviral cream when an outbreak happens can help in reducing the duration and prevent transmission.
- Getting enough sleep, eating a well-balanced diet and trying to keep stress to a minimum are also good ideas to keep your immune system healthy, helping it to fight off the virus.
It’s also important to keep in mind that once you are infected with the herpes simplex virus, you can spread the virus to others even when you don’t have an active cold sore. It’s a good idea to inform others that you have the virus and to take steps to prevent the spread of the virus.
If you are pregnant, it is important to inform your healthcare provider about your history of cold sores as the virus can be transmitted to the baby during birth.
