What the Yuck: How can I prevent cold sores?

Too embarrassed to ask your doctor about sex, body quirks, or the latest celeb health fad? In a regular feature and a new book, "What the Yuck?!," Health magazine medical editor Dr. Roshini Raj tackles your most personal and provocative questions. Send 'em to Dr. Raj at whattheyuck@health.com.

Q: I get cold sores all the time. It's so embarrassing - I don't want to go on dates or even be seen at work when I have one. Is there any way to prevent them?

Those pesky cold sores that pop up on or around your lips or nose are generally caused by a strain of the herpes simplex virus (HSV), known as HSV-1. True to the name, a cold can bring on a sore - and so can a fever, which is why they're sometimes called fever blisters.

Bolstering your immune system by eating well, getting plenty of rest and avoiding stress (that's the hard one, right?) may help you steer clear. Sun is also a common trigger, so don't ever step outside without a high-SPF lip balm.

There's no reason to suffer through embarrassing outbreaks: Ask your doctor for a prescription for an anti-viral medicine. If you fill it in advance and take it at the first hint of a sore, it makes your outbreak milder and less noticeable.

    6000 mg of lysine as soon as it starts will stop it in its tracks.

    l-lysine – readily available over the counter in drug stores and health food stores – will stop it before it starts. I suffered for years. This truly HELPS!

    Lysine found in the vitamin aisle. I take 500 mg everyday. I used to get them every fall and especially the spring. But not any more. If I do get a cold sore it's because I've forgotten to take lysine for a few days coupled with sun exposure and/or stress. I rarely get them any more. Lysine truly works. It's the only vitamin/supplement I take.

    I'm 55 yrs old. I've suffered from coldsores since my teens...as soon as I feel that tingly onset, usually stress, not taking care of myself, dehydrated, I take 1000mg of Lysine, then 500mg the following several days. Drink lots of H2O and flush your system...it always works...drys up in 48 hrs.

    Apply peroxide on a cold sore will help get rid of it within a day or two. Use a Q tip to put it on every half hour and it will dry it out.

    Most everyone here has it right. My wife (before we were married) and her boyfriend used to get cold sores all the time. I was friends with my wife before we started dating. I knew about Lysine and went out and bought a bottle for her and her boyfriend to share. It cleared both of them up in a few days. My wife never gets them anymore, but for people with a cronic situation, you might need to take a small dose every day.

    Another alternative, after taking the large doses for a few days, is to make sure you get a 'normal' amount of lysine in your diet. Lysine is found in things like Beef, Tofu (soybeans), Kidney beans, Chickpeas (hummus).

    None of the above really worked for me. Then I happened to have a cold sore when I went to the dentist who prescribed a small tube of Denavir to use on it and also tablets to take when I first felt any tingling. Both worked miracles! I never bothered with OTC meds again and keep Denavir and the tablets available all the time.

    Lysine works quite well as prevention. Also 1000 mg of Valtrex (prescription) if one occurs and then another 1000mg a day for 2 or 3 days. Things that contribute to cold sores, not enough rest, caffeine/stress, sun exposure. To speed up healing, take 1,000 Vit C (EmergenC) a day. Do not pop blister, keep lubricated with Vaseline or chapstick – Kielhls works quite well). While healing, neosporin can take discoloration away and you can hide with concealer.

    I had a horrible extended outbreak of cold sores last year. I read about dentists using lasers to treat them, so I tried it. The dentist zapped the cold sore and the skin around it. It cost $65, but I haven't had one since. I always used to get them in the same spot, so this may not work for everyone.

    I found an all-natural cure called MIRACLE LIPS that can prevent a cold sore from ever coming back! It's made with tea tree oil and bee propolis. I like the salve because it is thicker and stays on longer, but it comes in a roll-on serum as well. EXCELLENT healer of dry, chapped lips. If you feel a tingle of a cold sore come on, Miracle Lips will prevent it from coming out. If you have a cold sore, this will help it to heal fast. This has something to do with the tea tree oil being anti-viral. Check it out http://www.holocuren.com/miracle-lips.php
