• Herpes antiviral medication is used to treat infections caused by certain types of viruses, including herpes simplex (cold sores around the mouth), herpes zoster (shingles), and varicella (chickenpox).
• This medication is also used to treat genital herpes outbreaks.
• In individuals with frequent outbreaks, acyclovir helps reduce the number of future episodes.
• The viruses that cause these infections remain in the body even between outbreaks.
• Acyclovir decreases the severity and duration of outbreaks.
• When used for genital herpes, herpes antiviral medication speeds up the healing process, stops new sores from developing, and lessens discomfort and itching.
• Additionally, this medicine might shorten the time that discomfort persists after the sores heal.
• Furthermore, this medication may reduce the amount of time that discomfort lasts after the sores heal.

• Take herpes antiviral medication orally, with or without food, as directed by your physician, usually 2 to 5 times daily.
• Ensure adequate fluid intake while on this medication unless advised otherwise by your doctor.
• Before taking a dose in the liquid form, give the bottle a good shake.
• To guarantee the right dosage, measure the quantity precisely using an appropriate measuring tool or spoon; do not use regular spoons.
• Initiate treatment at the first sign of an outbreak for optimal efficacy, as directed by your physician. Delaying treatment may reduce its effectiveness.
• The dosage will be adjusted based on your medical condition and how you respond to the treatment. In children, dosage also depends on their weight.
• Maintain consistent levels of the medication in your body by taking it at evenly spaced intervals.
• For memory support, take medication at the same time every day.
• Continue the medication for the full prescribed duration; do not alter the dose, skip doses, or discontinue use without your doctor's approval.
• Please inform your physician if your condition persists or worsens.

• Let your physician or pharmacist know if you have any allergies to acyclovir, valacyclovir, or any other medications. Herpes antiviral medication may contain inactive ingredients that can cause allergic reactions or other issues.
• Disclose your medical history, particularly any kidney problems or immune system issues, to your doctor or pharmacist before using acyclovir.

• Elderly citizens might experience increased sensitivity to side effects, such as kidney problems, dizziness, drowsiness, and mental/mood changes (confusion, hallucinations, loss of consciousness).
• Acyclovir does not prevent the transmission of genital herpes. To reduce the risk of spreading herpes, avoid sexual contact during outbreaks or if symptoms are present. Use effective barrier methods (latex or polyurethane condoms/dental dams) during all sexual activity, even if no symptoms are visible.
• Herpes antiviral medication should only be used when necessary during pregnancy. Consult your physician about all the advantages and disadvantages.
• A nursing infant is generally not at risk from this medication, even if it is present in breast milk. Consult your physician before nursing.
