Understanding Cold Sores and Herpes Connection
What Causes Cold Sores?
Cold sores are always caused by herpes simplex viruses, predominantly HSV-1, though HSV-2 can occasionally cause oral lesions. The virus remains dormant in nerve cells after initial infection and can reactivate to cause recurrent outbreaks. Common triggers include stress, illness, sun exposure, hormonal changes, or a weakened immune system.
Treatment Options Available
Antiviral medications may help manage cold sore outbreaks when used appropriately. Aciclovir 400mg tablets represent a commonly prescribed treatment that works by inhibiting viral replication. EverydayMeds also stocks Valaciclovir 500mg tablets and topical Aciclovir 5% cream. Treatment typically works best when started at the first sign of tingling or burning sensations.
When to Seek Treatment
Consider consulting a healthcare professional if you experience frequent outbreaks, severe symptoms, or if cold sores don't heal within two weeks. Those with compromised immune systems may require different treatment approaches. Prescription antivirals available through EverydayMeds include Aciclovir tablets, Valtrex tablets, and various topical formulations.
Managing Outbreaks
Besides antiviral medication, keeping the affected area clean and avoiding touching or picking at blisters may help prevent secondary bacterial infection. Cold sores are most contagious when blisters are present, particularly during the weeping stage. Avoiding close contact and sharing personal items during active outbreaks helps prevent transmission to others.
