<human>: Hi. Yes just a quick question. I have a 10 year old son he is about 95 lbs. I take valtrex for cold sores. My sun also has breakouts of cold sores. I take 1 gram when i have a cold sore. Would it be safe for me to give my so I a half one when he has a break out?
<bot>: Welcome to ChatDoctorCold sores generally clear up without treatment. Treatment is needed if:-You have a weakened immune system-The cold sores don't heal within two weeks-Symptoms are severe-You have frequent recurrences of cold sores-You experience irritation in your eyesValtrex is not an appropriate choice for cold sores at 10 years of age. It would be better if you give him Acyclovir 200 mg 5 times a day for 7-10 days. These Chat Doctor. For further questions, do contact us.
