Valtrex alternatives: which antiviral might work for you?
Valtrex (valacyclovir) is a go-to for cold sores, genital herpes, and shingles. But it’s not the only option. If cost, dosing schedule, allergies, or resistance are issues, there are real alternatives you can discuss with your doctor or pharmacist. Below I list common alternatives, what they’re good for, and simple safety tips so you can have a productive conversation with your clinician.
Common drug alternatives and how they differ
Acyclovir (oral and IV) — The original drug in this family. It’s widely available and usually cheaper than brand-name Valtrex. The downside: you may need to take it more often each day. For severe infections or hospitalized patients, IV acyclovir is still the standard.
Famciclovir — Another oral antiviral that works well for shingles and recurrent genital herpes. Some people prefer it because dosing can be more convenient than acyclovir, and it’s effective for many who need short, early treatment for outbreaks.
Topical antivirals and OTC options — For cold sores that are mild, topical penciclovir (a prescription cream) or OTC agents like docosanol (Abreva) can help shorten healing when applied early. Topicals are less useful for genital herpes or shingles.
Generic valacyclovir — If the brand name Valtrex is pricey, ask about generic valacyclovir. Same active drug, usually lower cost.
Picking the right option & practical safety tips
What you choose depends on the infection, how often outbreaks happen, your kidney function, and whether you need suppression or episodic treatment. For quick relief, start antiviral therapy as soon as you notice early symptoms — antivirals work best when started early.
Kidney function matters. All these antivirals are cleared by the kidneys, so doses may need adjusting if you have reduced kidney function. Tell your provider about kidney disease or if you take other meds that affect the kidneys.
Side effects are usually mild: nausea, headache, or tiredness. Rarely, higher doses — especially in people with kidney problems — can cause confusion or more serious effects. If you notice sudden mental changes, severe rash, or trouble urinating, seek medical help.
Resistance is uncommon in healthy people but can happen in immunocompromised patients. If a medication stops working, your doctor may switch to a different antiviral or consider IV treatment.

Bottom line: there are solid alternatives to Valtrex. Acyclovir and famciclovir are the main ones, with topical options for mild cold sores. Talk to your clinician about your situation, kidney health, and budget so you get the best fit. If you want, bring a list of your meds and questions to your next appointment — that makes switching or starting treatment smoother.
