Common Aciclovir Treatment Issues and Solutions
Why Isn't My Aciclovir Working?
If aciclovir tablets appear less effective than expected, several factors may be involved. Treatment timing is crucial - aciclovir works best when started within 72 hours of symptom onset, ideally at the first tingling sensation. Starting treatment after blisters have fully formed may reduce effectiveness. The standard dose of aciclovir 400mg five times daily for five days should be followed precisely. Skipping doses or stopping treatment early may compromise results.
Delayed or Poor Response to Treatment
Some individuals may experience slower healing despite proper aciclovir use. This could indicate resistant viral strains, though resistance remains rare in immunocompetent patients. Stress, illness, or compromised immune function may also affect treatment response. If cold sores persist beyond 10 days or worsen during treatment, consult your healthcare provider. Alternative treatments like valaciclovir tablets may be considered for recurrent episodes.
Managing Side Effects
Common aciclovir side effects include nausea, headache, and diarrhoea. Taking tablets with food may reduce stomach upset. Adequate hydration helps prevent potential kidney-related effects, particularly important with higher doses. Rare but serious side effects include confusion, hallucinations, or severe skin reactions - seek immediate medical attention if these occur. Most side effects resolve once treatment is completed.
Recurring Cold Sore Outbreaks
Frequent outbreaks (more than six per year) may require suppressive therapy rather than episodic treatment. This involves taking lower daily doses of aciclovir to prevent outbreaks. Identifying and avoiding triggers like stress, sunlight, or illness may help reduce recurrence frequency. EverydayMeds stocks various aciclovir formulations including 400mg tablets for both episodic and suppressive treatment approaches.
When to Seek Further Medical Advice
Contact your healthcare provider if cold sores spread to eyes, persist beyond two weeks, or occur alongside fever and difficulty swallowing. Immunocompromised patients require specialist management. If standard aciclovir treatment repeatedly fails, resistance testing may be warranted, though this remains uncommon in typical cold sore cases.
