Buy Valaciclovir (Valacyclovir) 1000 mg Tablets online. Each tablet contains 1,000 mg (1 g) of valaciclovir, an antiviral medicine used to treat shingles, cold sores and genital herpes. It is the same active ingredient as the reference brand Valtrex. In the USA, UK and Australia it is a prescription medicine, so a valid prescription is needed for your order. See today’s price above and add it to your cart.
The 1,000 mg tablet is the higher strength, used where larger doses are needed, mainly for shingles and for one-day cold sore treatment. It helps outbreaks clear faster but does not cure the virus. Approved uses and legal status differ between countries, so this page covers the USA, UK, Australia, the UAE and Russia.
The reference (original) brand of valaciclovir is Valtrex, developed by GSK and sold in many countries. Valaciclovir is also sold as generic tablets and under other brand names, including Valtrex in the USA, UK, Australia and Russia (Вальтрекс). The spelling differs: valaciclovir is the international name and valacyclovir is the US spelling.
Compare the active ingredient, strength, manufacturer and packaging on your product. Different brands contain the same active ingredient at the same labelled strength but should not be assumed to have identical inactive ingredients or appearance.
Shingles: valaciclovir 1,000 mg is the dose used to treat shingles (herpes zoster) in adults. It works best when started within 72 hours of the rash appearing, and it can reduce pain and help the blisters heal.
Cold sores: a one-day course of two 1,000 mg doses, taken 12 hours apart, treats cold sores on the lips and face when started at the first tingle or sign.
Genital herpes: the US label describes 1 g twice a day for the first genital herpes episode, and 1 g once a day for suppression in some patients.
Your prescriber chooses the right strength and dose for you, and a lower dose may be needed if you have kidney problems.
Valaciclovir is a pro-drug of aciclovir (acyclovir). After you swallow it, the body converts it into aciclovir, which stops the herpes virus from copying its DNA. This limits how fast the virus multiplies, so sores heal sooner and symptoms ease. Valaciclovir is absorbed better than aciclovir tablets, which is why it can be taken fewer times a day. It does not remove the virus from the body.
The UK product information describes 1,000 mg three times a day for 7 days for shingles. For cold sores, it describes 2,000 mg (two 1,000 mg tablets) taken twice in one day, 12 hours apart. Start treatment as early as possible, at the first sign of symptoms.
Dosing rules vary by country. The US label also describes 1 g twice a day for 10 days for a first genital herpes episode, and 1 g three times a day for 7 days for shingles. Tablets can be taken with or without food and should be swallowed with a glass of water. Kidney problems and older age may need a lower dose. Always follow the leaflet in the pack and the advice of your prescriber or pharmacist.
Seek urgent medical attention for swelling of the face, lips or throat, difficulty breathing, severe skin reactions, passing very little urine, or confusion, hallucinations or severe drowsiness, which are more likely in older people and in people with kidney problems. In people with a weakened immune system, rare serious blood and kidney disorders have been reported.
Store the tablets in their original pack at room temperature, below 30°C, following any instructions printed on the pack. Keep out of the reach of children and do not use after the expiry date.
