Drug Interactions
Drug interactions can affect how your medications work or increase the risk of serious side effects. This document highlights only a few potential interactions. It’s important to maintain a list of all your medications—including prescription and over-the-counter drugs, as well as herbal products—and share it with your doctor and pharmacist. Never start, stop, or change the dosage of any medications without consulting your doctor.
Certain products may interact with this medication, especially those that can impact kidney function, such as nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen and naproxen.
Since valacyclovir is very similar to acyclovir, avoid using any medications that contain acyclovir while taking valacyclovir.
How long does Valacyclovir take to work?
The time it takes for valacyclovir to start working largely depends on the severity of the outbreak and how quickly you begin the medication after noticing symptoms.
For both initial and recurrent outbreaks, this antiviral medication can provide relief in as little as two to three days. Therefore, it’s important to take it as soon as you notice any symptoms or feel an outbreak coming on.
Keep in mind that response times can vary between individuals, so it may take longer or shorter for you to see results.
What happens if I miss a dose?
If you miss a dose, it could allow the virus to develop resistance to the medication, rendering valacyclovir ineffective.
Take the missed dose as soon as you remember. However, if it's nearly time for your next scheduled dose, skip the missed one. Do not take an extra dose!
What happens if I overdose?
As mentioned earlier, it’s crucial to avoid overdosing, as it can harm your health. If you believe you’ve taken too much, please contact us right away to ensure your safety and well-being.
How long does Valacyclovir stay in your system?
After oral ingestion, valacyclovir is quickly absorbed by the body and almost immediately converted into acyclovir and L-valine.
The half-life of the medication is approximately 2.5 to 3 hours in individuals, meaning that after this time, half of the drug will still be present in your bloodstream.
Can I still live an everyday life with herpes?
Absolutely! You might be surprised to discover how common herpes is. According to the World Health Organization (WHO), approximately 3.7 billion people under 50 worldwide have HSV-1 (oral herpes), while 417 million individuals aged 15 to 49 have HSV-2 (genital herpes).
This means you’re not alone, and there are many effective treatments available to help manage outbreaks. These treatments can suppress the virus and reduce the frequency of episodes. Some people experience outbreaks only once or twice a year, while others may go for years without any.
If you do have an episode, treatments can help make the symptoms manageable or even barely noticeable.
It’s also important to note that the herpes virus can be transmitted from an infected mother to her child during childbirth, especially in the case of genital herpes, making it crucial to prevent lesions during pregnancy.

What to avoid
- Remember that herpes infections are contagious. Taking Valacyclovir will not prevent you from passing it to others.
- Avoid having sex when you have an active outbreak. Do not let an infected area come into contact with your partner.
- Avoid touching infected areas and then touching other parts of your body, especially the eyes. Always wash your hands thoroughly.
- When applicable, use latex condoms during sexual intercourse.
- Avoid sharing medicine with other people, too. Valacyclovir is a prescription drug and is specifically for you only.
