Take Asiclo for the entire length of time prescribed by your doctor. Your symptoms may get better before the infection is completely treated.
Treatment with Asiclo 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 Asiclo. 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.
Asiclo can make your skin more sensitive to the sun. This increases your risk of sunburn. Avoid the sun if you can. If you can’t, be sure to wear protective clothing and apply sunscreen.

No clinically significant interactions have been identified.
Asiclo is eliminated primarily unchanged in the urine via active renal tubular secretion. Any drugs administered concurrently that compete with this mechanism may increase Asiclo plasma concentrations. Probenecid and cimetidine increase the area under the curve (AUC) of Asiclo by this mechanism, and reduce Asiclo renal clearance. Similarly, increases in plasma AUCs of Asiclo and of the inactive metabolite of mycophenolate mofetil, an immunosuppressant agent used in transplant patients have been shown when the drugs are coadministered. However, no dosage adjustment is necessary because of the wide therapeutic index of Asiclo.
Safety and effectiveness of oral formulations of Asiclo in pediatric patients younger than 2 years of age have not been established.
ZOVIRAX® (Asiclo) is contraindicated for patients who develop hypersensitivity or who are hypersensitive to Asiclo, valAsiclo or any other components of the formulations of ZOVIRAX®. For a complete listing, see Dosage Forms, Composition and Packaging section of the product monograph.
Charles River CD (Sprague-Dawley) rats were given suspensions of Asiclo by gavage. There were 50 male and 50 female rats at each of the following dose levels: 0, 50, 150 and 450 mg/kg. After 30 and 52 weeks of treatment, 10 male and 10 female rats from each group were necropsied. The remaining rats were dosed each day until natural mortality decreased a group size to approximately 20% of the number of animals of that sex present in the test groups when the study was started. All remaining rats were killed and necropsied when the 20% cut-off point was reached. This was during week 110 for the male rats and week 122 for the female rats. Tissues from control rats and those in the high-dose group were evaluated by light microscopy. Tissues from rats in the low and mid-dose groups having masses, nodules or unusual lesions were also examined by light microscopy. Fixed tissues from rats that were found dead during the first 52 weeks of the study were also evaluated by light microscopy.
No signs of toxicosis were observed. Plasma samples were collected 1.5 hours after dosing on days 7, 90, 209, 369, 771 (males only) and 852 (females only). Mean plasma levels found in high-dose males (450 mg/kg/day) at the times indicated above were as follows: 1.54, 1.63, 1.39, 1.60 and 1.70 μg/mL (6.84, 7.26, 6.17, 7.10 and 7.56 μM). Corresponding mean plasma levels for the high-dose females for the corresponding time periods were 1.76, 2.38, 2.12, 1.71 and 1.81 μg/mL (7.82, 10.58, 9.44, 7.62 and 8.03 μM). Plasma levels in both males and females at all dose levels after one year of treatment were generally comparable to plasma levels obtained at earlier samplings. Values for laboratory tests including hematology, clinical chemistry and ophthalmoscopy were all within the normal range. There were no drug-induced gross or microscopic lesions and there was no evidence that Asiclo affected survival.
Q: I am in stage 1 of multiple myeloma. I was diagnosed nearly 3 years ago. The last 3 summers I have had attacks of shingles, the 1st year I took 1000 mg of Asiclo daily and avoided the painful stage. Last year I missed the spots as they were on my back and suffered greatly for 2 to 3 months and I am still taking 1000 mg Asiclo per day. Each time I stop the medication the fever returns for a couple of days followed by the first few spots. I am on my 5th lot of Asiclo, starting with 1000 mg per day, increasing to 2,400 per day and 2 weeks ago was prescribed 4000 mg per day for 21 days. I have managed 10 days at this level but there are so many side effects, including kidney pain, so I have reduced to 3 tablets of 800 mg each. I feel less "in a fog" and slightly better already but am afraid when I stop the shingles will return. I am concerned about the side effects. Can you give me advice please? The side effects are basically 90% of the ones mentioned on the leaflet in the box of 800 mg tablets at 5 per day.
A: Shingles is a painful rash that is caused by the same virus (varicella virus) that causes the chickenpox. Only people who were infected with the virus and got chickenpox can get shingles. Unfortunately, people with weakened immune systems, from other diseases like cancer or treatments like chemotherapy, are at much greater risk of developing shingles. Drugs like Asiclo (Zovirax) work to reduce the ability of the virus to multiply and spread in the body. Asiclo has been shown to reduce the duration of infection and the severity of symptoms, but it relies on an individual's immune system to attack the virus. The drug itself does not kill the virus and that is likely the reason you continue to have symptoms and relapses. It is possible that some of the painful effects you are experiencing are the result of complications of shingles. One of these complications is called postherpetic neuralgia, which is the painful, tingling, and stinging pain at the site of the initial rash. There are medications that are used to help treat the pain associated with the nerve damage of shingles. These drugs include the anticonvulsants, such as Neurontin (gabapentin), Lyrica (pregabalin), and Tegretol (carbamazepine) and tricyclic antidepressants like Elavil (amitriptyline). For more specific information, consult with your doctor or pharmacist for guidance based on your health status and current medications, particularly before taking any action.

Which drugs or supplements interact with Asiclo?
Asiclo may decrease levels of phenytoin (Dilantin) or valproic acid (Depakote, Depakote ER). Probenecid (Benemid) may increase Asiclo serum levels by decreasing renal excretion of Asiclo. Asiclo may increase serum levels of theophylline (Theo-Dur, Respbid, Slo-Bid, Theo-24, Theolair, Uniphyl, Slo-Phyllin).
Combining Asiclo with cidofovir (Vistide), amphotericin B (Fungizone) or other drugs that reduce kidney function may increase harmful effects on the kidney.

Why it's used
Asiclo is used to treat viral infections. These include varicella-zoster (shingles), genital herpes, and chickenpox.
This drug doesn’t cure herpes infections. The herpes virus can stay in your body for a long time and cause symptoms again later.
Asiclo must be taken at the specific dose suggested, without taking basically of it, or stopping the therapy before it's time. Asiclo procedure ought to be started as quickly as feasible after the very first indications of the infection are presented (scorchings, burning etc), due to the fact that it will certainly be most reliable then. It's essential to consider that although Asiclo helps to keep the signs controlled, it does not cure the infection. When having sexual intercourse and needs to wear a prophylactic (or make certain the condom is used by the sex-related companion), the patient stays infectious. You could take Asiclo with some meals or without, but always similarly.
