Clinovir Cream (Acyclovir) can be used in the treatment of ” cold sores/ fever blisters” ( herpes labialis). It may speed up the healing of the sores as well as reduce symptoms (such as pain, tingling, burning to itch, and so on) Acyclovir is part of a group of drugs called antivirals. It is effective in stopping the spread of viruses. It is not a cure for herpes, and it will not stop the spread of the virus to another person. It doesn’t stop a future outbreak.
How to use Acyclovir Cream
Take a look at the leaflet for patients that is available at Your pharmacy. Ask your physician or pharmacist should you have any concerns.
Apply the medication when you notice the first signs of an infection (such as burning, tingling, and redness). Cleanse the hands with soap and water prior to and after applying the medication. Dry and clean the areas affected prior to taking the medicine. Apply the cream to the area affected and gently rub it in, typically 5 times every day (every 3-4 minutes) for 4 consecutive days to treat painful cold sores or as prescribed by your physician. Apply enough cream to cover all affected areas (red/tingling/burning areas, sores).
Apply the cream to the skin only. Make sure to not apply this medicine to areas such as the eyes or the nose within the mouth or in the vagina. If you happen to get the medication in these areas, wash it out with plenty of water.
Dosage is determined by your health condition, the type of infection, and your response to treatment. Don’t take this medication more frequently or for longer than you are prescribed.
Make sure to use this medication on a regular basis to reap the greatest benefit. The best results are when the amount absorption by the skin is at a steady level. So, you must use this medication at regular intervals. To make it easier to remember take it, do it at the same time throughout the day.
To avoid getting rid of the medication, don’t shower, bathe or swim within a few minutes of applying it.
If you are applying the treatment to genital herpes sores, wear an e-sock or gloves to prevent spreading the disease.
Don’t apply other products for the skin (such as medications, cosmetics, sunscreens as well as lip balms) in the absence of being instructed to apply them by your physician. Don’t cover the area with waterproof or plastic bandages unless instructed to do so by your physician.
Sores that are cold ( herpes) can easily spread. Acyclovir cream doesn’t stop spreading herpes. Avoid contact with other people (such as the kissing) in the course of a flare till the cold sores are completely healed. Be sure not to contact the sore that is cold or scratch it, and clean your hands when you contact the sores that are cold.
If you’re using the drug acyclovir to treat herpes genital, it is essential to adhere to secure sex techniques to lower the possibility of spreading the herpes virus to your spouse even if there aren’t any symptoms. Always utilize the condom comprised of polyurethane or latex. If you are experiencing symptoms or experiencing an outbreak, don’t be sexually intimate or with your companion.
Inform your doctor when your condition continues or becomes worse after treatment is done.
Why is this medication prescribed?
Acyclovir cream is used to treat cold sores (fever blisters; blisters that are caused by a virus called herpes simplex) on the face or lips. Acyclovir ointment is used to treat first outbreaks of genital herpes (a herpes virus infection that causes sores to form around the genitals and rectum from time to time) and to treat certain types of sores caused by the herpes simplex virus in people with weak immune systems. Acyclovir is in a class of antiviral medications called synthetic nucleoside analogs. It works by stopping the spread of the herpes virus in the body. Acyclovir does not cure cold sores or genital herpes, does not prevent outbreaks of these conditions, and does not stop the spread of these conditions to other people.
How should this medicine be used?
Topical acyclovir comes as a cream and an ointment to apply to the skin. Acyclovir cream is usually applied five times a day for 4 days. Acyclovir cream may be applied at any time during a cold sore outbreak, but it works best when it is applied at the very beginning of a cold sore outbreak when there is tingling, redness, itching, or a bump but the cold sore has not yet formed. Acyclovir ointment is usually applied six times a day (usually 3 hours apart) for 7 days. It is best to begin using acyclovir ointment as soon as possible after you experience the first symptoms of infection. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Use topical acyclovir exactly as directed. Do not use more or less of it or use it more often than prescribed by your doctor.

Keep this medication in the container it came in, with the cap on and tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom). Never leave this medication in your car in cold or hot weather.
Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA’s Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.
It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org
