Valtrex (Valacyclovir) Buyer and Patient Handbook in South Africa

What is Valtrex?

Valtrex is an antiviral medication containing the active ingredient valacyclovir, used to treat infections caused by herpes viruses. It is approved by the South African Health Products Regulatory Authority (SAHPRA) for conditions such as genital herpes, shingles (Herpes Zoster), and cold-spot (herpes labialis). The drug is supplied as oral tablets.

Who Should Use Valtrex?

• Adults diagnosed with a first episode or recurrent genital herpes.
• Individuals experiencing shingles or post-herpetic Neuralgia.
• Patients with frequent cold-spot outbreaks seeking faster healing.
• People whose immune system is compromised (e.g., HIV, organ-transplant recipients) and who have been advised by a health professional to take an antiviral.

How Does It Work?

Valtrex is a prodrug that the body quickly converts to Acyclovir, the active antiviral. Acyclovir blocks the viral DNA polymerase enzyme, preventing the virus from replicating its genetic material. Think of it as cutting the power supply to a factory that the virus needs to produce new copies of itself. By halting replication, the infection resolves more rapidly and the severity of symptoms is reduced. The medication has a low potential for misuse, but patients with a history of kidney disease should be monitored closely.

Why Choose Valtrex?

• Convenient dosing: Only one or two tablets per day for most indications, compared with several daily doses of acyclovir.
• Proven efficacy: Clinical trials show faster lesion healing and reduced Pain duration.
• Availability: Both brand-name Valtrex and a generic valacyclovir are marketed in South Africa, giving patients a cost-effective option.
• Off-label use: Some clinicians may consider Valtrex for prevention of cytomegalovirus (CMV) infection in transplant patients, but this requires specialist guidance.
