Basic Valtrex Question and Answers

Before you start taking Valtrex, there are certain questions that should be answered to get the most out of this treatment.

What Is Valtrex?

Basically, it’s a popular antiviral medication taken by patients to treat different herpes viruses, cold sores, shingles and other similar infections. It belongs to antiviral antibiotics, and this means that it’s effective only against infections caused by different viruses.

You shouldn’t take it for other medical conditions because they will become resistant.

What Are Its Possible Side Effects?

Valtrex may result in specific adverse effects, just like other medications, but they are very rare and most of them are not serious. As an example, some of the most common side effects experienced by patients who use it include:

  • Nausea and vomiting;
  • Stomach pain and headaches;
  • New cold symptoms and reduced white blood cells;
  • Allergies and increased liver enzymes;
  • Skin rash and diarrhea;
  • Dizziness and joint pain.

There are some serious side effects that may develop when taking Valtrex. Once you notice any of the following severe symptoms, you need to go to the hospital immediately:

  • Confusion and depression;
  • Agitation and delirium;
  • Hallucination and seizures;
  • Increased heart rates and encephalopathy.

What Are Valtrex Recommended Doses?

It’s possible to take this medication both with and without food.

If you have any kidney problems, you should use it in lower doses because of possible health risks. For patients who need to treat shingles or herpes zoster, it’s necessary to start taking 1 g Valtrex 3 times a day (this treatment course usually lasts only for one week).

This step should be taken once you notice the first symptoms of this common viral infection to get the most out of it. To treat chickenpox, you need to take 20 mg of Valtrex three times a day (this treatment usually lasts only for 5 days).

You should use this medication right after noticing the first symptoms of this disease, but your maximum daily dosage shouldn’t exceed 1,000 mg.

People who want to treat initial episodes of genital herpes should take 1 g of this medicine 2 times a day, and their treatment lasts for about 10 days.

To treat recurrent genital herpes, you should start taking Valtrex in 500 mg doses 2 times a day (this treatment lasts for 3 days). If you need to cure cold sores, take 2 g of this medication each 12 hours during one day.

Are There Any Possible Drug Interactions?

Be aware of specific medications that may potentially interact with this viral antibiotic because they must be avoided. For instance, Valtrex may possibly interact with cimetidine and probenecid, thus, leading to severe side effects and other health risks.

Discuss other meds and supplements that you’re taking with your physician to determine whether they can be safely combined with Valtrex.

You also need to be examined by doctors to define the best dosage and treatment length.
