Aciclovir Tablets

Description

Acyclovir oral tablet is a prescription drug that’s available as the brand-name drug Zovirax. It’s also available as a generic drug. Generic drugs usually cost less than the brand-name version. In some cases, they may not be available in all strengths or forms as the brand-name drug.

Acyclovir also comes as an oral capsule, oral suspension, buccal tablet, topical cream, and topical ointment. In addition, acyclovir is available as an intravenous drug, which is only given by a healthcare provider.

This drug may be used as part of a combination therapy. This means you may need to take it with other medications.

Important Information

Take acyclovir 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.

Why it’s used

Acyclovir is used to treat viral infections. These include varicella-zoster (shingles), genital herpes, and chickenpox.

This drug doesn’t cure herpes infections. The herpes virus can stay in your body for a long time and cause symptoms again later.

How it works

Acyclovir belongs to a class of drugs called antivirals. A class of drugs is a group of medications that work in a similar way. These drugs are often used to treat similar conditions.

Acyclovir works by lowering the ability of the herpes virus to multiply in your body. This treats the symptoms of your infection. However, this drug doesn’t cure herpes infections. Herpes infections include cold sores, chickenpox, shingles, or genital herpes. Even with this drug, the herpes virus may still live in your body. Your symptoms may occur again later even after the symptoms of your current infection go away.

Warnings for certain groups

For people with kidney problems: If you have kidney problems or a history of kidney disease, you may not be able to clear this drug from your body well. This may increase the levels of this drug in your body and cause more side effects.

This medication may also decrease your kidney function. This means your kidney disease may get worse. Your doctor will adjust your dose depending on how well your kidneys are working.

For pregnant women: Acyclovir is a category B pregnancy drug. That means two things:

  1. Studies of the drug in pregnant animals have not shown a risk to the fetus.
  2. There aren’t enough studies done in pregnant women to show if the drug poses a risk to the fetus.

Talk to your doctor if you’re pregnant or planning to become pregnant. This drug should be used only if the potential benefit justifies the potential risk to the fetus.

Call your doctor right away if you become pregnant while taking this drug.

For women who are breastfeeding: Acyclovir may pass into breast milk and may cause side effects in a child who is breastfed. Talk to your doctor if you breastfeed your baby. You may need to decide whether to stop breastfeeding or stop taking this medication.

For seniors: The kidneys of older adults may not work as well as they used to. This can cause your body to process drugs more slowly. As a result, more of a drug stays in your body for a longer time. This raises your risk of side effects.

For children: This drug hasn’t been studied in children younger than 2 years.

 Take as directed

Acyclovir oral tablet is used for short-term treatment of genital herpes, shingles, and chicken pox. It’s used for long-term treatment of recurring genital herpes. This drug comes with serious risks if you don’t take it as prescribed.

If you stop taking the drug suddenly or don’t take it at all: The symptoms of your infection may not get better or may get worse.

If you miss doses or don’t take the drug on schedule: Your medication may not work as well or may stop working completely. If you’re taking this drug to prevent flare-ups of your infection, a certain amount needs to be in your body at all times. You shouldn’t stop taking this drug without talking to your doctor first.

What to do if you miss a dose: Take your dose as soon as you remember. But if you remember just a few hours before your next scheduled dose, take only one dose. Never try to catch up by taking two doses at once. This could result in dangerous side effects.

If you take too much: You could have dangerous levels of the drug in your body and experience more severe side effects. If you think you’ve taken too much of this drug, call your doctor or local poison control center. If your symptoms are severe, call 911 or go to the nearest emergency room right away.

How to tell if the drug is working: The symptoms of your infection will get better.
