What is Palovir Topical?

Palovir Topical 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.

Palovir Topical 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. Palovir Topical is also used to prevent recurrent genital herpes infections. Although Palovir Topical will not cure herpes, it does help relieve the pain and discomfort and helps the sores (if any) heal faster.

Palovir Topical 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.

Palovir Topical 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, Palovir Topical 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

Palovir Topical 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.

Tablet: Palovir Topical oral formulations are indicated for the treatment of herpes simplex virus infections of the skin and mucous membranes including initial and recurrent genital herpes.

Palovir Topical oral formulations are indicated for the suppression (prevention of recurrences) of recurrent herpes simplex infections in immune-competent patients. Palovir Topical oral formulations are indicated for the prophylaxis of herpes simplex infections in immune-compromised patients.

Palovir Topical oral formulations are indicated for the treatment of varicella infections (chicken-pox) and herpes zoster (shingles).

Studies have shown that early treatment of shingles with Palovir Topical has a beneficial effect on pain and can reduce the incidence of post-herpetic neuralgia (zoster-associated pain).

Palovir Topical oral formulations are indicated for the management of certain severely immunocompromised patients, namely those with advanced HIV disease (CD4+ counts <200/mm3, including patients with AIDS or severe ARC) or following bone marrow transplantation.

Studies have shown that oral Palovir Topical given in conjunction with antiretroviral therapy (mainly oral RETROVIR) reduced mortality in patients with advanced HIV disease and that oral Palovir Topical preceded by one month's treatment with intravenous Palovir Topical reduced mortality in bone marrow transplant recipients. In addition, oral Palovir Topical provided effective prophylaxis for herpes virus disease.

Uses of Palovir Topical in details

There are specific as well as general uses of a drug or medicine. A medicine can be used to prevent a disease, treat a disease over a period or cure a disease. It can also be used to treat the particular symptom of the disease. The drug use depends on the form the patient takes it. It may be more useful in injection form or sometimes in tablet form. The drug can be used for a single troubling symptom or a life-threatening condition. While some medications can be stopped after few days, some drugs need to be continued for prolonged period to get the benefit from it.

This medication is used to treat cold sores around the mouth (caused by herpes virus) that keep coming back.

Palovir Topical 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. Palovir Topical 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 Palovir Topical buccal

Read the Patient Information Leaflet and Instructions for Use provided by your pharmacist before you start using Palovir Topical 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 Palovir Topical 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.

Palovir Topical description

Palovir Topical IV contains Acyclovir as the sodium salt. Each 250-mg vial contains sodium ion approximately 26 mg. When reconstituted as directed, Palovir Topical IV for infusion has a pH of approximately 11.

Palovir Topical dosage

Tablet: Adults: Treatment of Herpes Simplex: For treatment of herpes simplex infections, 200 mg Palovir Topical should be taken five times daily at approximately four-hourly intervals omitting the night time dose. Treatment should continue for five days but in severe initial infections may have to be extended.

In severely immune-compromised patients (e.g. after marrow transplant) or in patients with impaired absorption from the gut the dose can be doubled to 400 mg or, alternatively, intravenous dosing could be considered.

Dosing should begin as early as possible after the start of an infection; for recurrent episodes this should preferably be during the prodromal period or when lesions first appear.

Suppression of Herpes Simplex: For suppression of herpes simplex infections in immune-competent patients, 200 mg Palovir Topical should be taken four times daily at approximately six-hourly intervals.

Many patients may be conveniently managed on a regimen of 400 mg Palovir Topical taken twice daily at approximately twelve-hourly intervals.

Dosage titration down to 200 mg Palovir Topical taken thrice daily at approximately eight-hourly intervals or even twice daily at approximately twelve-hourly intervals, may prove effective.

Some patients may experience break-through infections on total daily doses of 800 mg Palovir Topical.

Therapy should be interrupted periodically at intervals of six to twelve months in order to observe possible changes in the natural history of the disease.

Prophylaxis of Herpes Simplex: For prophylaxis of herpes simplex infections in immune-compromised patients, 200 mg Palovir Topical should be taken four times daily at approximately six-hourly intervals.

In severely immune-compromised patients (e.g. after marrow transplant) or in patients with impaired absorption from the gut the dose can be doubled to 400 mg or, alternatively, intravenous dosing could be considered.

The duration of prophylactic administration is determined by the duration of the period at risk.

Treatment of Varicella and Herpes Zoster: For treatment of varicella and herpes zoster infections, 800 mg Palovir Topical should be taken five times daily at approximately four-hourly intervals, omitting the night time dose. Treatment should continue for seven days.

In severely immune-compromised patients (e.g. after marrow transplant) or in patients with impaired absorption from the gut, consideration should be given to intravenous dosing.

Dosing should begin as early as possible after the start of an infection. Treatment yields better results if initiated as soon as possible after onset of the rash.

Management of Severely Immunocompromised Patients: For management of severely immunocompromised patients, 800 mg Palovir Topical should be taken four times daily at approximately six-hourly intervals.

In the management of bone marrow recipients this would normally be preceded by up to one month's therapy with intravenous Palovir Topical.

The duration of treatment studied in bone marrow transplant patients was 6 months (from 1 to 7 months post-transplant). In patients with advanced HIV disease, study treatment was 12 months, but it is likely that these patients would continue to benefit from a longer duration of treatment.

Infants and Children: For treatment of herpes simplex infections, and for prophylaxis of herpes simplex infections in the immune-compromised, children aged two years and over should be given adult dosages and infants and children below the age of two years should be given half the adult dose.

For treatment of varicella infections in children: 6 years and over: 800 mg Palovir Topical four times daily; 2-<6 years: 400 mg Palovir Topical four times daily; Under 2 years: 200 mg Palovir Topical four times daily. Dosing may be more accurately calculated as 20 mg Palovir Topical/kg bodyweight (not to exceed 800 mg) four times daily. Treatment should continue for five days.

No specific data are available on the suppression of herpes simplex infections or the treatment of herpes zoster infections in immune-competent children.

Limited data suggest that for management of severely immunocompromised children, over two years of age, the adult dose may be given.

Elderly: The possibility of renal impairment in the elderly must be considered and the dosage should be adjusted accordingly.

Adequate hydration of elderly patients taking high oral doses of Palovir Topical should be maintained.

Renal Impairment: Caution is advised when administering Palovir Topical oral formulations to patients with impaired renal function. Adequate hydration should be maintained.

In the treatment and prophylaxis of herpes simplex infections in patients with impaired renal function, the recommended oral doses will not lead to accumulation of Palovir Topical above levels that have been established safe by intravenous infusion. However, for patients with severe renal impairment (creatinine clearance less than 10 ml/minute) an adjustment of dosage to 200 mg twice daily at approximately twelve-hourly intervals is recommended.

In the treatment of varicella and herpes zoster infections, and in the management of severely immunocompromised patients it is recommended to adjust the dosage to 800 mg twice daily, at approximately twelve-hourly intervals, for patients with severe renal impairment (creatinine clearance less than 10 mL/minute) and to 800 mg three times daily, at intervals of approximately eight hours, for patients with moderate renal impairment (creatinine clearance in the range 10 to 25 mL/minute).

Injection: To be gives as intravenous infusion over 1 hour.

A course of treatment with Palovir Topical IV for infusion usually lasts 5 days, but this may be adjusted according to the patient's condition and response to therapy. Treatment for herpes encephalitis usually lasts 10 days.

Treatment for neonatal herpes usually lasts 14-21 days.

The duration of prophylactic administration of Palovir Topical IV for infusion is determined by the duration of the period at risk.

Adults: Treatment of Herpes Simplex: Obese patients should be dosed at the recommended adult dose using ideal body weight, rather than actual body weight.

Patients with herpes simplex (except herpes encephalitis) should be given Palovir Topical IV for infusion in doses of 5 mg/kg bodyweight every eight hours if renal function is not impaired.

Patients with herpes encephalitis should be given Palovir Topical IV for infusion in doses of 10 mg/kg bodyweight every eight hours provided renal function is not impaired.

Prophylaxis of Herpes Simplex in Immune-compromised Patients: Obese patients should be dosed at the recommended adult dose using ideal body weight, rather than actual body weight.

Refer to adult dosing recommendations for the treatment of herpes simplex with Palovir Topical IV for infusion.

Treatment of Varicella and Herpes Zoster: Obese patients should be dosed at the recommended adult dose using ideal body weight, rather than actual body weight.

Patients with varicella zoster infections should be given Palovir Topical IV for infusion in doses of 5 mg/kg bodyweight every eight hours if renal function is not impaired.

Immune-compromised patients with varicella zoster infections should be given Palovir Topical IV for infusion in doses of 10 mg/kg bodyweight every eight hours provided renal function is not impaired.

Infants and Children: The dose of Palovir Topical IV for infusion for infants and children aged between 3 months and 12 years is calculated on the basis of body surface area. Infants and children 3 months of age or older with herpes simplex (except herpes encephalitis) or varicella zoster infections should be given Palovir Topical IV for infusion in doses of 250 mg per square metre body surface area every 8 hours if renal is not impaired.

In immune-compromised infants and children with varicella zoster infections or herpes encephalitis, Palovir Topical IV for infusion should be given in doses of 500 mg per square metre body surface area every 8 hours if renal function is not impaired.

Infants and children with impaired renal function require an appropriately modified dose, according to the degree of impairment.

Neonates: The dosage of Palovir Topical IV for infusion in neonates is calculated on the basis of bodyweight.

The recommended regimen for treatment for known or suspected neonatal herpes is Palovir Topical IV 20 mg/kg body weight IV every 8 hours for 21 days for disseminated and CNS disease, or for 14 days for disease limited to the skin and mucous membranes. Patients with impaired renal function require an appropriately modified dose, according to the degree of impairment.

Elderly: The possibility of renal impairment in the elderly must be considered and the dosage should be adjusted accordingly.

Adequate hydration should be maintained.

Renal Impairment: Caution is advised when administering Palovir Topical IV for infusion to patients with impaired renal function. Adequate hydration should be maintained.

Dosage adjustment for patients with renal impairment is based on creatinine clearance, in units of mL/min for adults and adolescents and in units of mL/min/1.73 m2 for infants and children less than 13 years of age. The following adjustments in dosage are suggested: See Table 1 and Table 2.

Clinical Trials Experience

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 Palovir Topical Cream and 1,161 with placebo (vehicle) cream. Local application site reactions were reported by 5% of patients receiving Palovir Topical 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 Palovir Topical Cream and placebo. Three patients on Palovir Topical 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 Palovir Topical Cream compared with vehicle using single occluded and semi-occluded patch testing methodology. Both Palovir Topical 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 Palovir Topical 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 Palovir Topical Cream and placebo, and these reactions to both Palovir Topical 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 Palovir Topical 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 Palovir Topical Cream.

General: Angioedema, anaphylaxis.

Skin: Contact dermatitis, eczema.
