Acivir 800 mg Tablet

Acivir 800 mg Tablet is an oral antiviral medicine that contains 800 mg of acyclovir in each tablet. It belongs to the nucleoside antiviral class and is used to treat certain infections caused by herpes viruses, including shingles, genital herpes, and cold sores, as directed by a clinician. This Acivir 800 mg Tablet is a higher-strength tablet intended for specific treatment regimens prescribed by a doctor.

How it works: Acyclovir works by interfering with the virus’s ability to copy its genetic material, which slows down the spread of the infection. In tablet form, Acivir 800 mg Tablet is swallowed so the medicine can be absorbed into the body and reach the virus where it is active.

The Acivir 800 mg Tablet is a higher-strength option, so it is not meant for routine use by everyone or for self-starting at home. A doctor may choose this strength when a treatment plan calls for fewer tablets per dose or when a higher acyclovir dose is needed for a specific herpes infection.

• Shingles (herpes zoster)
• Genital herpes outbreaks
• Cold sores in certain situations
• Prevention of recurrent herpes infections
• Other herpes virus infections as prescribed

• Swallow Acivir 800 mg Tablet whole with a full glass of water unless your doctor tells you otherwise.
• Take it exactly on the schedule prescribed; spacing doses evenly helps keep drug levels steady.
• Start the medicine as soon as possible after symptoms begin if your prescriber instructs you to use it that way.
• You can take this tablet with or without food, but taking it with food may help if it upsets your stomach.
• Drink plenty of fluids while using acyclovir unless your doctor has told you to limit fluids.
• Do not crush or split the tablet unless your pharmacist or doctor says it is safe for your specific prescription.

Each Acivir 800 mg Tablet provides 800 mg of acyclovir per tablet. The exact dose, how many times per day it is taken, and the maximum daily amount depend on the infection being treated and the patient’s kidney function, so your doctor determines the schedule. This is a higher-strength tablet, so do not use it more often or in larger amounts than prescribed.

Do not change your dose or stop the medicine without speaking to your doctor.
