Acyclovir
"Was given this medication for cold sores which had gone down into my throat thanks to having a weak immune system from Lupus. This needs to be tested on viral bronchitis. I had a cold sore starting as the symptoms of viral bronchitis started so began taking the med yesterday (day 5 of cold) and took my first dose right at 24 hours ago. Im still very tired and feel a little feverish but my nose and chest are 90% better. My mom has had this cold/virus for 14 days and still fighting it, I have lupus so every cold takes me weeks to overcome. Im sure the med is helping with my cold."
