Acyclovir belongs to the family of medicines called antivirals, which are used to treat infections caused by viruses. Usually these medicines work for only one kind or group of virus infections.
Acyclovir is used to treat the symptoms of chickenpox, shingles, herpes virus infections of the genitals (sex organs), the skin, the brain, and mucous membranes (lips and mouth), and widespread herpes virus infections in newborns. Acyclovir is also used to prevent recurrent genital herpes infections. Although Acyclovir will not cure herpes, it does help relieve the pain and discomfort and helps the sores (if any) heal faster.
Acyclovir may also be used for other virus infections as determined by your doctor. However, it does not work in treating certain virus infections, such as the common cold.
Acyclovir is available only with your doctor's prescription.
Once a medicine has been approved for marketing for a certain use, experience may show that it is also useful for other medical problems. Although not specifically included in product labeling, Acyclovir by injection is used in certain patients with the following medical conditions:
Herpes simplex (for prevention of repeated infections) in people with a weak immune system
Herpes zoster infections of the eye
Shingles (for prevention of repeated infections) in people with a weak immune system
Acyclovir indications
An indication is a term used for the list of condition or symptom or illness for which the medicine is prescribed or used by the patient. For example, acetaminophen or paracetamol is used for fever by the patient, or the doctor prescribes it for a headache or body pains. Now fever, headache and body pains are the indications of paracetamol. A patient should be aware of the indications of medications used for common conditions because they can be taken over the counter in the pharmacy meaning without prescription by the Physician.

This medication is used to treat cold sores around the mouth (caused by herpes virus) that keep coming back.
Acyclovir is an antiviral drug. However, it is not a cure for the infection. The virus that causes infection continues to live in the body between outbreaks. Acyclovir makes outbreaks shorter and less severe. It helps the sores heal faster, keeps new sores from forming, and decreases pain/itching. This medication may also help reduce how long pain lasts after the sores heal.
How to use Acyclovir buccal
Read the Patient Information Leaflet and Instructions for Use provided by your pharmacist before you start using Acyclovir buccal tablets and each time you get a refill. If you have any questions, ask your doctor or pharmacist.
Apply one tablet within one hour after you have the first symptom of a cold sore, and before a cold sore appears. Symptoms may include itching, redness, burning, or tingling. Apply the tablet on the same side of your mouth as the cold sore symptoms.
Before applying the tablet, find the area in your mouth in which to place the tablet. It should be placed on the upper gum, just above the left or right incisor tooth. The incisors are the teeth just to the left and right of your two front teeth. With dry hands, remove one tablet from the blister pack and place it in your mouth with the round side facing against your gum and gently push it into place. Remove your hand from inside your mouth and gently press your finger on the outside of your upper lip for 30 seconds. This will make the tablet stick to your gum. The tablet will slowly dissolve over time and should be left in place. You may eat and drink while using this medication. Do not crush, chew, suck, or swallow the tablet.
If the tablet does not stick to your upper gum or falls off within the first 6 hours after you apply it, the same tablet should be placed back onto your upper gum right away. If it still does not stay in place, apply another Acyclovir tablet to your upper gum.
If you accidentally swallow the tablet within the first 6 hours after placement, drink a glass of water and apply a new dose to your gum. However, if the tablet has been in place 6 hours or longer and it falls out or you swallow it, do not re-apply the tablet.
Avoid doing things that may keep the buccal tablet from sticking to your gum, including touching or pressing the tablet after placement, wearing an upper denture that interferes with tablet placement, chewing gum, and brushing your teeth while the tablet is in place. You may gently rinse your mouth with water to clean your teeth while the tablet is in place. Drink plenty of liquids if you have dry mouth.
This medication works best when started at the first sign of a cold sore, as directed by your doctor. It may not work as well if you delay treatment.
Tell your doctor if your condition does not improve or if it worsens.

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug, and may not reflect the rates observed in practice.
In five double-blind, placebo-controlled trials, 1,124 patients were treated with Acyclovir Cream and 1,161 with placebo (vehicle) cream. Local application site reactions were reported by 5% of patients receiving Acyclovir Cream and 4% of patients receiving placebo. The most common adverse reactions at the site of topical application were dry lips, desquamation, dryness of skin, cracked lips, burning skin, pruritus, flakiness of skin, and stinging on skin; each adverse reaction occurred in less than 1% of patients receiving Acyclovir Cream and placebo. Three patients on Acyclovir Cream and one patient on placebo discontinued treatment due to an adverse event.
An additional study, enrolling 22 healthy adults, was conducted to evaluate the dermal tolerance of Acyclovir Cream compared with vehicle using single occluded and semi-occluded patch testing methodology. Both Acyclovir Cream and placebo showed a high and cumulative irritation potential. Another study, enrolling 251 healthy adults, was conducted to evaluate the contact sensitization potential of Acyclovir Cream using repeat insult patch testing methodology. Of 202 evaluable subjects, possible cutaneous sensitization reactions were observed in the same 4 (2%) subjects with both Acyclovir Cream and placebo, and these reactions to both Acyclovir Cream and placebo were confirmed in 3 subjects upon rechallenge. The sensitizing ingredient(s) has not been identified.
The safety profile in patients 12 to 17 years of age was similar to that observed in adults.
Postmarketing Experience
In addition to adverse events reported from clinical trials, the following events have been identified during post-approval use of Acyclovir Cream. Because they are reported voluntarily from a population of unknown size, estimates of frequency cannot be made. These events have been chosen for inclusion due to a combination of their seriousness, frequency of reporting, or potential causal connection to Acyclovir Cream.
Use this medication for the full prescribed length of time. Your symptoms may improve before the infection is completely cleared. Acyclovir will not treat a viral infection such as the common cold or flu.
Treatment with Acyclovir should be started as soon as possible after the first appearance of symptoms (such as tingling, burning, blisters).
Herpes infections are contagious and you can infect other people, even while you are being treated with Acyclovir. Avoid letting infected areas come into contact with other people. Avoid touching an infected area and then touching your eyes. Wash your hands frequently to prevent passing the infection to others.
Acyclovir will not prevent the spread of genital herpes. Avoid sexual intercourse or use a latex condom to prevent spreading the virus to others.
