Generic Name: acyclovir (injection) (a SY klo veer)
Brand Names: Zovirax


 
What is the most important information I should know about acyclovir?
Use this medication for the entire length of time prescribed by your doctor. Your symptoms may get better before the infection is completely treated.
Treatment with acyclovir should be started as soon as possible after the first appearance of symptoms (such as tingling, burning, blisters).
Herpes infections are contagious and you can infect other people, even while you are being treated with acyclovir. Avoid letting infected areas come into contact with other people. Avoid touching an infected area and then touching your eyes. Wash your hands frequently to prevent passing the infection to others.
 

What is acyclovir?
Acyclovir is an antiviral drug. It slows the growth and spread of the herpes virus so that the body can fight off the infection. Acyclovir will not cure herpes, but it can lessen the symptoms of the infection.
Acyclovir injection is used to treat severe infections caused by herpes viruses, including severe forms of genital herpes, shingles, herpes encephalitis (swelling of the brain), and herpes infections in people with other diseases that weaken the immune system.
Acyclovir may also be used for purposes other than those listed in this medication guide.
 

What should I discuss with my healthcare provider before using acyclovir?
Do not use this medicine if you are allergic to acyclovir or valacyclovir (Valtrex).
Before using acyclovir, tell your doctor if you are allergic to any drugs, or if you have:
       · kidney disease (or if you are on dialysis);
       · liver disease;
       · a brain or nervous system disorder such as Parkinson's disease, schizophrenia, or tardive dyskinesia;
       · breathing problems; or
       · an electrolyte imbalance (such as high or low calium , sodium, or potassium blood levels).
If you have any of these conditions, you may not be able to use acyclovir, or you may need a dosage adjustment or special tests during treatment.
FDA pregnancy category B. This medication is not expected to be harmful to an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant during treatment. Herpes virus can be passed from an infected mother to her baby during childbirth. If you have genital herpes, it is very important to prevent herpes lesions during your pregnancy so that you do not have a genital lesion when your baby is born.
Acyclovir passes into breast milk and may harm a nursing infant. Do not take this medication without telling your doctor if you are breast-feeding a baby.
 

How should I take acyclovir?
Use this medication exactly as it was prescribed for you. Do not use the medication in larger amounts, or take it for longer than recommended by your doctor. Follow the directions on your prescription label.
Treatment with acyclovir should be started as soon as possible after the first appearance of symptoms (such as tingling, burning, blisters).
Drink plenty of water while you are taking acyclovir to keep your kidneys working properly.
This medication is given as an injection through a needle placed into a vein. Your doctor, nurse, or other healthcare provider will give you this injection. The medicine must be given slowly through an IV infusion, and can take at least 1 hour to complete.
You may be given instructions on how to use your injections at home. Do not use this medicine at home if you do not fully understand how to give the injection and properly dispose of needles and other items used in giving the medicine.
Use each needle and syringe only one time. With your medicine you will receive a puncture-proof container for used needles and syringes. If you do not receive a container, ask your pharmacist for one. Keep this container out of the reach of children and pets. Your pharmacist can tell you how to properly dispose of the container.
Use this medication for the entire length of time prescribed by your doctor. Your symptoms may get better before the infection is completely treated. Acyclovir will not treat a viral infection such as the common cold or flu.
Lesions caused by herpes viruses should be kept as clean and dry as possible. Wearing loose clothing may help to prevent irritation of the lesions.
Store acyclovir at room temperature away from moisture and heat.
 

What happens if I miss a dose?
Use the medication as soon as you remember. If it is almost time for the next dose, skip the missed dose and use the medicine at the next regularly scheduled time. Do not use extra medicine to make up the missed dose.
 

What happens if I overdose?
Seek emergency medical attention if you think you have used too much of this medicine.
Symptoms of an acyclovir overdose may include agitation, seizure (convulsions), hallucinations, and urinating less than usual or not at all.
 

What should I avoid while taking acyclovir?
Herpes infections are contagious and you can infect other people, even while you are being treated with acyclovir. Avoid letting infected areas come into contact with other people. Avoid touching an infected area and then touching your eyes. Wash your hands frequently to prevent passing the infection to others.
