Zovirax cream (aciclovir)
Zovirax cream has been clinically proven to be able to prevent cold sores from appearing. The cream contains the unique antiviral agent Acyclovir which prevents the cold sore virus from replicating. Zovirax Cream has been prescribed for over 10 years to more that 22 million patients around the world.
Acyclovir is an antiviral drug which acts against the Herpes viruses, including herpes simplex 1 and 2 (cold sores and genital herpes), varicella-zoster (shingles and chicken pox), and the Epstein-Barr virus (mononucleosis). It does not cure herpes infections but decreases pain and itching and promotes healing. Oral Zovirax decreases the frequency and severity of recurrent sores.
A cold sore is an infection which is caused by an organism called the herpes simplex virus. This virus is different from the virus that causes colds. Although most of the population carries the virus, not everyone gets attacks of cold sores. The first infection usually occurs in early childhood, for instance after being kissed by a person with the infection. The virus passes through the skin, travels up a nerve and hides in a nerve junction until reactivated.
The virus is capable of infecting other parts of the body. If you rub your eyes after touching a cold sore, you could start an eye infection. Herpes simplex infection of the eye can lead to ulcers on the window on the eye (cornea). Similarly, you should avoid kissing if you or your partner has active cold sores. Oral sex with a partner with an active cold sore may lead to a genital herpes infection.
Directions for use:
Ideally you should always keep a tube of Zovirax cream with you so that you can treat your next attack in time to be able to prevent its appearance.
The tingling, burning or itching sensation, on your lips or around your nose, that you get before a cold sore develops is your reminder to use Zovirax cream as soon as possible. If used at this stage, Zovirax cream can prevent the cold sore blister from appearing. If your cold sore has already appeared, Zovirax cream can help speed the healing process.
How to apply:
Wash your hands before and after treating the cold sore so as to avoid making it worse, spreading the virus to other body parts, or giving the infection to someone else. Squeeze a small amount of cream onto your finger. Apply enough ointment to cover the lesion(s) completely. A one-half inch ribbon of ointment should cover approximately 4 square inches of surface area.
Apply to the affected area five times daily, about every four hours. If you forget a treatment, apply some as soon as you remember. Then continue as before. Do not exceed the stated dose. Continue treatment for five days. If your cold sore has not healed after this time, treatment may continue for up to a further five days. If full healing has still not occurred after ten days, or if your cold sore has become very severe, consult your doctor. Use Zovirax topical for the full amount of time prescribed, even if you begin to feel better. Your symptoms may start to improve before the infection is completely treated.
Zovirax cream belongs to a group of herpes medications.
