Acyclovir Oral Uses
This drug is used to treat outbreaks of herpes simplex on the skin (mouth, lips, genitals), outbreaks of shingles (herpes zoster), and chickenpox. This medication may also be used to help prevent outbreaks of herpes in patients with frequent outbreaks.
The viruses that cause these infections are similar. They live in the body quietly until an outbreak is triggered. Acyclovir is not a cure for the infections, but treatment of an outbreak can speed up healing of the sores, decrease pain/itching/formation of new sores, and lower the risk of other problems from the virus (e.g., infection spreading to other parts of the body/organs, persistent pain after sores heal).
How To Use Acyclovir Oral
Take this medication by mouth with or without food, usually 2 to 5 times daily or as directed by your doctor. It is very important to continue taking this medication exactly as prescribed by your doctor. Unless your doctor directs you otherwise, drink plenty of fluids while taking this medication.
If you are using the liquid form of this medication, shake the container well before pouring each dose. Measure the dose carefully using a special measuring device/spoon. Do not use a household spoon because you may not get the correct dose.
Dosage is based on your weight, kidney function, medical condition, and response to treatment.
This medication works best when the amount of drug in your body is kept at a constant level. Therefore, take this drug at evenly spaced intervals. To help you remember, take it at the same times each day.
This medication works best when started at the first sign of an outbreak as directed by your doctor.
Do not take more or less of this drug than prescribed or stop taking it even for a short time unless directed to do so by your doctor. Skipping or changing your dose without approval from your doctor may decrease the effectiveness of the drug. Stopping the medication too early may result in a return of the outbreak.
Tell your doctor if your condition persists or worsens.
