What is acyclovir ointment and what is it used for:
Acyclovir ointment is an antiviral medication used to treat herpes simplex virus infections of the skin, including cold sores (herpes labialis) and genital herpes (herpes simplex virus 2). It works by preventing the virus from multiplying and spreading. Acyclovir ointment can help reduce the duration and severity of symptoms, but it does not cure the underlying infection.
How to use acyclovir ointment:
Acyclovir ointment should be applied topically to the affected area of the skin. Wash your hands before and after applying the ointment. Use a clean cotton swab or finger to apply a thin layer of ointment to the affected area. Apply the ointment every three hours, six times a day, for seven days. It is important to start treatment as soon as possible after the appearance of symptoms.
Possible side effects of acyclovir ointment:
Acyclovir ointment may cause some side effects, including:
Burning, stinging, or itching at the application site
Dry or cracked lips
If any of these side effects persist or worsen, inform your doctor immediately. Seek emergency medical attention if you experience any signs of an allergic reaction, such as hives, difficulty breathing, or swelling of the face, lips, tongue, or throat.
Precautions and warnings for acyclovir ointment:
Before using acyclovir ointment, inform your doctor if you have any medical conditions, such as a weakened immune system or kidney disease. Acyclovir ointment may interact with certain medications, including probenecid, which can increase the levels of acyclovir in the blood.
Acyclovir ointment is not recommended for use during pregnancy or while breastfeeding, as it may harm the developing fetus or nursing infant. It is important to attend regular doctor appointments and report any new or worsening symptoms to your healthcare provider while using acyclovir ointment.
