Does acyclovir actually work?
Treatment with valacyclovir or acyclovir is effective in reducing subclinical and total HSV shedding.
The frequency of both total and subclinical shedding decreased with antiviral therapy by 91%–97% when measured by culture and by 76%–82% when measured by PCR..
Do antivirals weaken immune system?
Whereas AZT, ribavirin, or ganciclovir were antiproliferative, ddI or acyclovir had little, if any, effect on PBMC mitogenesis. The inhibitory effects of antivirals on immune cells may contribute to the immune deterioration observed in patients following prolonged use of the drugs.
What should you not take with acyclovir?

Does acyclovir speed up healing?
It can speed up healing of the sores and decrease symptoms (such as tingling, pain, burning, itching). Acyclovir belongs to a class of medications known as antivirals. It works by stopping the growth of the virus. This medication does not cure herpes, and it does not prevent passing the infection to someone else.
How long after starting acyclovir are you contagious?
You can spread the virus even when you don’t have any symptoms of a cold sore, though you’re usually most contagious when you have them. However, this is much less likely than if contact occurred when a cold sore was present. Cold sores are contagious until they go away completely, which usually takes about two weeks.
Do Antivirals kill viruses?
Antiviral drugs are a class of medication used for treating viral infections. Most antivirals target specific viruses, while a broad-spectrum antiviral is effective against a wide range of viruses. Unlike most antibiotics, antiviral drugs do not destroy their target pathogen; instead they inhibit its development.
How much acyclovir should I take during an outbreak?
Typical dosage for reinfection (flare-up of the infection): 200 mg every 4 hours, five times per day, for 5 days. You should take this drug as soon as the first signs of a flare-up appear.
Does valacyclovir work better than acyclovir?
Valacyclovir is the most commonly prescribed medication for genital herpes and cold sores; it’s a longer-acting version of acyclovir. Taken regularly, valacyclovir has been shown to be effective suppressive therapy against recurrent genital herpes and cold sores, reducing the frequency of outbreaks.
Does acyclovir weaken immune system?
This medication may rarely cause a life-threatening disorder that affects the blood cells, kidneys, and other parts of the body. This disorder is more likely to occur if you have conditions related to a weakened immune system (such as HIV disease, bone marrow transplant, kidney transplant).
Is acyclovir hard on the kidneys?
Abstract. Acute kidney injury is an unfortunate complication of acyclovir therapy secondary to crystal-induced nephropathy. It is characterized by a decrease in renal function that develops within 24–48 hours of acyclovir administration indicated by a rapid rise in the serum creatinine.
Can you drink alcohol with acyclovir?
Alcohol will not interfere with the way the antiviral drugs works. Acyclovir will still be effective.
How many years can you take acyclovir?
The tablets, capsules, and suspension are usually taken with or without food two to five times a day for 5 to 10 days, starting as soon as possible after your symptoms begin. When acyclovir is used to prevent outbreaks of genital herpes, it is usually taken two to five times a day for up to 12 months.
Can you take antivirals everyday?
If you have outbreaks often, you may want to consider taking an antiviral drug every day. Doctors call this suppressive therapy. For someone who has more than six outbreaks a year, suppressive therapy can reduce the number of outbreaks by 70% to 80%.
How long do antivirals take to work?
For most initial herpes outbreaks and cases of recurring herpes, valacyclovir takes effect very quickly and provides some level of relief in as little as two to three days. Generally, the sooner you take valacyclovir after noticing symptoms, the faster it will be to provide relief.
