He added, \u201cIn fact, if you&#8217;re treating a cold sore outbreak, you may only need to take valacyclovir for one day.\u201d<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The length of time someone will need valacyclovir therapy depends on their immune system, the condition they\u2019re treating, the frequency of recurrence, and the severity of their herpes outbreaks.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">There are two standard treatment options when it comes to valacyclovir.\u00a0<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">There is <\/span><b>daily suppressive therapy<\/b><span style=\"font-weight: 400;\">, where a person takes the medication every day. This is recommended for those who have frequent outbreaks in order to reduce recurrence.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">There is also <\/span><b>episodic treatment<\/b><span style=\"font-weight: 400;\">, in which a person only takes valacyclovir during a flare-up to reduce and resolve symptoms faster.<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">\u201cThe decision to use daily or episodic therapy is usually based on the patient\u2019s personal preference and medical history,\u201d explained Dr. Hannah Kopelman, a dermatologist at <\/span><a href=\"https:\/\/drkopelman.com\/\"><span style=\"font-weight: 400;\">Kopelman Aesthetic Surgery<\/span><\/a><span style=\"font-weight: 400;\"> and the host of the weekly <\/span><a href=\"https:\/\/hannahkopelman.com\/dermatology-podcast\/\"><span style=\"font-weight: 400;\">Derm Club podcast<\/span><\/a><span style=\"font-weight: 400;\">.<\/span><\/p>\n<h2 id=\"what-does-valacyclovir-treat\"><span style=\"font-weight: 400;\">What does valacyclovir treat?<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">\u201cValacyclovir is an antiviral medication that treats herpes-related conditions, including cold sores (herpes simplex virus-1), genital herpes (herpes simplex virus-2), and shingles (herpes zoster),\u201d Dr. Kopelman said. \u201cIt works by preventing the virus from multiplying, which helps reduce the severity and duration of outbreaks.\u201d<\/span><\/p>\n<h3 id=\"cold-sores-hsv-1\"><span style=\"font-weight: 400;\">Cold sores (HSV-1)<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">The <\/span><a href=\"https:\/\/www.who.int\/news-room\/fact-sheets\/detail\/herpes-simplex-virus\"><span style=\"font-weight: 400;\">World Health Organization<\/span><\/a><span style=\"font-weight: 400;\"> estimates nearly two-thirds of adults under 50 years of age have herpes simplex virus-1 (HSV-1) also known as herpes labialis, is more commonly known as \u201ccold sores.\u201d HSV-1 is\u00a0 typically acquired during childhood. This type of herpes infection is characterized by small blisters around the mouth and lips.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">While there are over-the-counter topical creams to speed up recovery, Valtrex (valacyclovir) is the go-to prescription treatment of many healthcare providers.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The <\/span><a href=\"https:\/\/www.singlecare.com\/prescription\/valacyclovir-hcl\/dosage\"><span style=\"font-weight: 400;\">valacyclovir dosage<\/span><\/a><span style=\"font-weight: 400;\"> for the treatment of herpes labialis depends on the frequency of your outbreaks and whether you commonly have recurrent cold sores. Those who have 10 or more outbreaks per year will typically opt for suppression therapy and take 500 mg of valacyclovir each day. For episodic treatment, patients are recommended to take 2,000 mg twice in one day.\u00a0<\/span><\/p>\n<h3 id=\"how-fast-does-valacyclovir-work-for-cold-sores\"><span style=\"font-weight: 400;\">How fast does valacyclovir work for cold sores?<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Valacyclovir works best when taken at the first sign of cold sore symptoms. While your lesion won\u2019t heal immediately after taking the medication, valacyclovir will <\/span><a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC149313\/\"><span style=\"font-weight: 400;\">help decrease<\/span><\/a><span style=\"font-weight: 400;\"> the amount of pain and discomfort within the first 24\u201348 hours. While a cold sore typically lasts up to 10 days without treatment, those taking valacyclovir should notice them clearing up within two to three days.<\/span><\/p>\n<h3 id=\"genital-herpes-hsv-2\"><span style=\"font-weight: 400;\">Genital Herpes (HSV-2)<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Herpes simplex virus-2, or HSV-2, is acquired from sexual contact and is often referred to as genital herpes. While not as prevalent as HSV-1, it\u2019s still a <\/span><a href=\"https:\/\/www.singlecare.com\/blog\/news\/herpes-statistics\/\"><span style=\"font-weight: 400;\">common condition<\/span><\/a><span style=\"font-weight: 400;\">. It\u2019s estimated that 519 million individuals from 15\u201349 years of age have this herpes simplex virus type.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Valacyclovir is also the standard treatment for HSV-2. The valacyclovir dosage depends on whether it\u2019s the first outbreak or a recurrent episode for the infected person. The immune system has not yet encountered this virus on the first outbreak, so for most individuals, the first time involves the most severe symptoms. The valacyclovir dose for the initial herpes outbreak is 1,000 mg twice daily for 10 days. The dose of valacyclovir for recurrent outbreaks of genital herpes is 500 mg twice a day for three days.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u201cValacyclovir can also help reduce the chances of spreading herpes,\u201d Dr. Dasgupta said.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Daily suppression therapy is recommended for those with frequent recurrences of outbreaks or for those wanting to lower their risks of transmission to sexual partners. <\/span><a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/16556084\/\"><span style=\"font-weight: 400;\">Multiple studies<\/span><\/a><span style=\"font-weight: 400;\"> throughout the years found that daily suppression therapy can reduce the risk of HSV transmission. Wearing condoms during sexual activity can also help protect a person\u2019s sex partners from the spread of this HSV type.\u00a0<\/span><\/p>\n<h3 id=\"how-long-does-it-take-for-valacyclovir-to-work-on-genital-herpes\"><span style=\"font-weight: 400;\">How long does it take for valacyclovir to work on genital herpes?<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Valacyclovir <\/span><a href=\"https:\/\/www.singlecare.com\/blog\/how-long-does-valacyclovir-take-to-work\/\"><span style=\"font-weight: 400;\">begins working<\/span><\/a><span style=\"font-weight: 400;\"> two to three days after the first dose for a genital herpes outbreak. It works best when taken immediately after the first sign of an outbreak. Valacyclovir helps decrease the amount of pain, burning, and discomfort experienced. However, the healing process for the blisters takes a longer time, with lesions clearing up in nine to 10 days.<\/span><\/p>\n<h3 id=\"oral-herpes\"><span style=\"font-weight: 400;\">Oral herpes<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Oral Herpes can refer to either type of herpes simplex virus. While less common, it is possible to spread HSV-2 through oral sex, causing someone to have an HSV-2 outbreak in their mouth. In the same way, if someone with a cold sore (HSV-1) performs oral sex, they could spread HSV-1 to the genital area. The only way to distinguish between the two herpes virus infections is with lab testing from a healthcare professional.<\/span><\/p>\n<h3 id=\"shingles-herpes-zoster\"><span style=\"font-weight: 400;\">Shingles (herpes zoster)<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Herpes zoster, more commonly referred to as <\/span><a href=\"https:\/\/www.singlecare.com\/conditions\/shingles-treatment-and-medications\"><span style=\"font-weight: 400;\">shingles<\/span><\/a><span style=\"font-weight: 400;\">, is caused by the varicella-zoster virus. While you might not recognize the name, the virus is extremely common and is also the cause of the highly contagious childhood virus chickenpox.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The varicella-zoster virus is latent in the body after chickenpox clears up and can reappear in adulthood as shingles. Shingles causes a painful rash. While the exact cause of the reactivation is unknown, periods of stress and illness could be a factor. That means if you\u2019ve had chickenpox, you could be at risk for shingles.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The valacyclovir dosage for shingles is 1,000 mg three times a day for seven days. This treatment works best when taken immediately after the first symptoms of shingles appear.<\/span><\/p>\n<h3 id=\"how-long-does-it-take-for-valacyclovir-to-work-on-shingles\"><span style=\"font-weight: 400;\">How long does it take for valacyclovir to work on shingles?<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Valacyclovir should begin working to reduce pain and burning sensations from shingles within two to three days after starting treatment.<\/span><\/p>\n<h2 id=\"potential-side-effects-of-prolonged-valacyclovir-use\"><span style=\"font-weight: 400;\">Potential side effects of prolonged valacyclovir use<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">\u201cProlonged use of valacyclovir is generally well tolerated,\u201d Dr. Kopelman said. However, she did mention there are potential side effects, which include:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Headache<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Nausea<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Abdominal discomfort<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">While rare, long-term use may lead to kidney issues, especially for those who already have kidney problems. Neurological toxicity is also a possible concern.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u201cRegular monitoring by a healthcare provider is advised if you&#8217;re on long-term suppressive therapy,\u201d Dr. Kopelman said.<\/span><\/p>\n<h2 id=\"the-bottom-line\"><span style=\"font-weight: 400;\">The bottom line<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Valacyclovir does not need to be taken forever; however, those with frequent outbreaks can benefit from daily suppression therapy. The prescription antiviral drug works best when taken at the first sign of an outbreak of HSV-1, HSV-2, or shingles.
