Common Use

Aciclovir is an antiviral medication that mimics the molecular structure of purine nucleosides. It is effective in treating viral infections such as cold sores and inhibiting the growth of viruses like Herpes simplex, Varicella zoster (responsible for chickenpox and shingles), Epstein Barr Virus (linked to glandular fever), and to a lesser extent, Cytomegalovirus (CMV). It also aids in preventing genital herpes and viral infections in individuals with weakened immune systems. Additionally, Aciclovir can reduce the duration of pain after sores heal and minimize the risk of the virus spreading to other body parts, particularly in immunocompromised patients.

Dosage and Direction

Take Aciclovir orally with or without food, typically 2 to 5 times daily as prescribed. Always take it with a glass of water and at regular intervals. Do not exceed the recommended dosage. Complete the full course of treatment even if symptoms improve. For liquid formulations, shake the bottle well before use and measure the dose with a proper measuring device. Avoid using household spoons to ensure accurate dosing. Dosage adjustments are based on medical condition, response to treatment, and for children, body weight.

Precautions

Consult your healthcare provider before using Aciclovir if you have kidney disease, allergies, or are pregnant, planning pregnancy, or breastfeeding. Inform your doctor about all medications, including prescription, over-the-counter drugs, vitamins, and supplements. Aciclovir can pass into breast milk, so discuss breastfeeding with your healthcare provider before starting treatment.

Contraindications

Aciclovir Injection is not recommended for individuals with hypersensitivity to aciclovir or valaciclovir.

Possible Side Effects

Serious side effects requiring immediate medical attention include:

• Allergic reactions (rash, itching, swelling of the face, lips, or tongue)
• Chest pain, confusion, hallucinations, or tremors
• Dark urine, sun sensitivity, or skin changes (redness, blistering, peeling)
• Seizures, urinary issues, unusual bleeding, or jaundice

Common side effects that may not need medical attention include diarrhea, fever, headache, nausea, vomiting, and stomach upset. Consult your doctor if these persist or worsen.

Drug Interactions

Aciclovir may interact with other medications, such as:

• Phenytoin (Fosphenytoin): May reduce phenytoin levels, requiring dosage adjustment.
• Probenecid: Can increase Aciclovir levels, raising the risk of side effects.
• Tenofovir: Aciclovir may elevate Tenofovir levels, potentially increasing side effects.

Your healthcare provider may adjust dosages to manage these interactions.

Missed Dose

If you miss a dose, take it as soon as you remember. If it's nearly time for your next dose, skip the missed one and resume your regular schedule. Do not double the dose.

Overdose

Seek emergency medical help if you suspect an overdose. Symptoms may include seizures, hallucinations, and reduced urination.

Storage

Store Aciclovir at a controlled room temperature between 15°C to 25°C (59°F to 77°F). Keep it out of reach of children and do not share the medication. Use it only for the prescribed purpose.
