Norbarc Aciclovir Cream 5 g (wrong smpc)

Who is this for?

Aciclovir is an antiviral medicine that works by stopping viruses from multiplying in your body, especially the herpes virus that causes cold sores, genital herpes, and chickenpox.

Inhibits viral DNA polymerase by acting as a nucleoside analogue, blocking herpesvirus DNA replication and halting viral spread. Requires viral thymidine kinase for phosphorylation to its active form, ensuring selective toxicity against infected cells.

Is Aciclovir safe to take with another drug?

For cold sores or genital herpes: Take one 200 mg tablet five times a day (every 4 hours while awake, skip the night dose) for 5 days. For shingles: Take 800 mg five times a day for 7 days. Drink plenty of water while taking aciclovir to protect your kidneys. You can take it with or without food.

If you miss a dose, take it as soon as you remember. But if it's almost time for the next dose, skip the missed one and continue as normal. Do not take a double dose to make up for it.

• Headache
• feeling dizzy
• nausea or stomach upset
• tiredness
• skin rash or itching (especially with the cream)

Probenecid (used for gout) can increase aciclovir levels in your blood and raise the risk of side effects. Be careful if you are also taking medicines that can affect the kidneys, such as some antibiotics like gentamicin. Always tell your pharmacist about all medicines you are taking.

Store in a cool, dry place below 25°C — away from direct sunlight and heat, which can be intense in Nigeria. Keep the cream tube tightly closed after use. Always keep out of reach of children.
