Aciclovir Cream

Aciclovir cream is a type of antiviral medicine that combats outbreaks of the herpes simplex virus. It’s usually applied to blisters that form around the lips (cold sores), or in some cases, external genital herpes.

Aciclovir cream is a popular treatment due to how effective it is as reducing symptoms of herpes simplex infections, and the fact that it rarely causes adverse effects. However, it might not be suitable for some people, including those with a weakened immune system.

Aciclovir cream won’t kill the herpes simplex virus, but it can stop it from multiplying and spreading to other parts of your body or to other people as long as it’s used as directed and from the moment that you first notice symptoms.

Aciclovir cream

Aciclovir cream is an antiviral medication that’s used to treat outbreaks of herpes simplex infections. Herpes simplex is the virus that causes cold sores and genital herpes. Although there are two types of herpes simplex infection, aciclovir cream is effective against both, and can help to reduce both the severity of your symptoms, and how long you experience them for.

Unfortunately, aciclovir cream can’t prevent future outbreaks of herpes simplex infections, but it can help with current infections by stopping the virus from multiplying and spreading, and therefore reducing the amount of time you experience the outbreak for.

It’s important to wash your hands both before and after applying aciclovir cream to reduce the risk of spreading the virus to other parts of your body or to other people. Because herpes simplex blisters are incredibly contagious, it’s a good idea to make sure that your sores don’t come into contact with others until they’re completely healed. This may mean avoiding kissing if you have a cold sore, or avoiding sex if you have genital herpes.

Aciclovir for cold sores

Aciclvoir cream is one of the most common treatments for cold sores due to its effectiveness and the fact that most people don’t experience adverse effects when using it. When you use aciclovir cream for cold sores, you should start applying it as soon as you notice symptoms of an outbreak (for example, a tingling or itching sensation around your lips, or when you first notice a blister starting to form). Using the cream as soon as you notice symptoms of a herpes simplex infection means that it has time to work before the virus has chance to multiply and spread, reducing your risk of a larger infection.

Aciclovir cream should be applied to cold sores 5 times per day, or once every 4 hours. You should apply the cream for five days at first. Most people find that within this time, the medication has worked and the cold sore has either disappeared or drastically improved. However, some infections may take longer to heal. If your symptoms are still present after five days of using aciclovir cream, you can continue to use it for a further five days. You shouldn’t use the cream for more than a maximum of 10 days without seeing your own GP for advice. If your symptoms still haven’t disappeared after 10 days of using aciclovir cream, you should make an appointment with your doctor to discuss alternative treatments, or whether a tablet form of aciclovir would be beneficial for you.

Aciclovir cream genital herpes

Although aciclovir cream is most commonly used to treat cold sores (outbreaks of herpes simplex blisters around the lips), it can also be used to treat genital herpes in some cases. However, it’s important to know that you should only ever apply aciclovir cream to external sores, and not ones that may exist inside your penis, vagina or anus.

In the same way that you’d apply aciclovir cream to cold sores, you should apply it to genital herpes 5 times a day, also spaced out in 4-hour intervals.

As with cold sores, sores caused by genital herpes should usually begin to clear up within 5 days of using aciclovir cream, but you can use it for a maximum of 10 days before making an appointment with your own GP if the blisters haven’t healed in this time.

If you have herpes inside your vagina, anus, or urethra, you should contact your GP for advice, as it’s likely that you will need to take a tablet form of aciclovir instead of a cream.

Acyclovir cream side effects

Aciclovir cream is one of the most popular treatments for outbreaks of herpes, as it’s effective and doesn’t cause adverse effects in most people. However, this doesn’t guarantee a lack of side effects.

Whilst most people don’t experience any kind of irritation when using aciclovir cream, some people do complain of mild skin reactions where it has been applied. Some of the most common side effects of aciclovir cream include:

  • Burning or stinging sensation after application
  • Itching in the local area
  • Dry or flaky skin where the cream has been applied
  • Skin redness
  • Rash

Many people that do experience side effects of aciclovir cream find them mild or easy to deal with. However, if you find that the side effects are causing a great deal of discomfort, you should stop using the cream and consult with your own GP or local pharmacist.

As with most medications, aciclovir cream can also provoke an allergic reaction in some people. If you notice any signs of irritation or allergic reaction after using the cream, you should stop using it and seek urgent medical help.

Cold sore cream

It’s important to look at the ingredients of any cold sore cream before you buy one. Some popular brands use ammonia to combat symptoms of cold sores, which may be more appropriate for those that aren’t able to use aciclovir for whatever reason. However, some people find these types of creams to be less effective than ones that contain aciclovir.

If you aren’t sure which cold sore cream you should use, you can always ask your local pharmacist for advice, who will recommend a cream based on your symptoms and whether or not you’re allergic to any medications.

Aciclovir cold sore cream is thought to be one of the most effective remedies available for cold sores and herpes simplex blisters, and is now available to buy online from Doctor4U.
