acyclovir for Herpes Simplex: I started taking acyclovir 2 days ago and I Already feel better my outbreak is 90% clear and so far no side effects. I take 800mg 5 times a day for 7 days...O and I take it for having the shingles which is like herpes
acyclovir for Herpes Simplex: I was prescribed this medication a few months ago and I absolutely love it. Whenever I feel a cold sore coming on, I take three 400mg tablets every 8 hours (the recommended dose by my doctor) and it stops the cold sore right in its tracks.
If I'm lucky, I catch the cold sore in the tingling stage and immediently take the pills, and that usually stops the cold sore from breaking out. If I do end up getting a cold sore, I keep using the pills and it Speeds up the process and stops the cold sore from growing any bigger. This medication is amazing and I am so glad to finally have found something that actually works, as I am almost 20 years old and have been suffering from cold sores since age 4.
acyclovir for Herpes Zoster: I had a random herpes zoster outbreak (shingles) on my back and was prescribed 800mg 5x day for 7 days. It dried up my blisters within two days and I healed nicely. I did however have headaches and dry mouth with severe nausea and vomiting the last two days on the medication. Those are side effects and being that I was on a strong dose, these side effects really affected me.
acyclovir for Herpes Simplex: I've experienced cold sores ever since i was 13 years old, but being a college student now and constantly stressed out ive been getting them more frequently. I tried everything from abreva, all the house remedies, and ointments, but none of them worked. So i got prescribed to the 400mg dose and these pills do wonders! I felt the bump yesterday and the first stage of the blister had started and i took the dosage i was prescribed and woke up today with the bump the same size. So i took another one and within two hours it was completely gone. I am so happy to have found something that finally works

acyclovir for Herpes Simplex: I have been plagued by cold sores since I was 14 years old and have struggled at finding any effective medication, including Abreva. A year ago I could feel an outbreak coming and did some research online and found acyclovir. I read the reviews and figured I'd try it. Within 24 hours my forming cold sore stopped and began to heal and shrink, within 3 days it was almost non existent. Yesterday I woke up and realized over night with no notice a huge sore had formed and the virus was on full unrestricted attack. Went out, got Acyclovir and again, within 24hours what was bound to be a huge long drawn out cold sore had stopped, shrunk and began healing. Acyclovir with Abreva has proved to be a miracle. TRY IT! P.S No side effects for me.

Review by Dolce Vita (taken for 6 months to 1 year):
acyclovir for Herpes Simplex, Suppression: My face has developed more cystic adult acne that takes longer to heal. My eye whites have yellowish tint. I notice I bruise easy and minor injuries take a long time to heal. I have lost weight (the good part)
I feel fatigued frequently and lack energy
acyclovir for Mononucleosis: I had some unusual herpes-like symptoms that came with my mononucleosis, and they prescribed this to me thinking that even if it did not help, it would not hurt me. I had found astonishing results and it made all my symptoms less drastic and made me get over it much faster.
acyclovir for Herpes Simplex, Mucocutaneous/Immunocompromised Host: My daughter is 5 years old & has a primary immunodeficiency (natural killer cell deficiency). When she takes this medicine for the treatment of her HSV (oral), her chronic HSV is less severe, and although new ones do form, they fade away very quickly and at some points, her face is clear. She has taken it for as long as 5 weeks at a time and will begin taking prophylactic doses of this medication (long term) by next month. We (my husband and myself) believe that her initial outbreak of HSV was caused by the Varicella vaccine. Later blood tests revealed her immunodeficiency.
acyclovir for Herpes Simplex: I have been on the medicine for almost 2 years now and I have only had 3 outbreaks so far, don't know what causes them but I start taking my meds 3 times a day with an outbreak and hope it works.
Review by Occasional (taken for less than 1 month):
acyclovir for Herpes Simplex: I woke up early in the morning and felt the tingle of a new cold sore. I went to the doc and got a prescription within the hour and took my first 400 mg pill of acyclovir. I used Abreva right when I felt it and a few times that night. I took 3 pills over the course of the first day. When I woke up the next morning the bump had not gotten bigger but had not gotten smaller either. It was hardly noticeable I should add. I took 3 more pills over the course of the second day and the bump has not grown any bigger. I woke up the 3rd morning and it has shrunk in size. I encourage everyone to get a large stock of acyclovir and take it IMMEDIATELY when the tingle is felt. Even if it is just maybe a cold sore. It is totally worth it.

acyclovir for Herpes Zoster: So far after one pill, and 34 more to go (5 a day) it feels like the needles are still stabbing me in the upper back. I'm 46 and I had my first outbreak of shingles when I was 17. I had the full blown blisters and all - Knives was the feeling then. The Doc just changed my script from Famvir to this Acyclovir I hope it will work the same. Mine are 800mg 5 times a day and they gave me three refills. They don't know what to do with me.

acyclovir for Herpes Simplex: I used to get Cold Sores rarely, but more stress & it's been a nightmare! On top of that I kept missing work whenever I got breakouts (for a week at a time) because I'm a Spokemodel. I started to get desperate, because I couldn't be reliable for work & started losing huge amounts of my income. Plus Cold Sores are a major bummer to go through.
Finally talked to my Dr. I've been taking only 200mg a day. Then a few days ago, I took a chance and tanned my face & whammo I started getting a breakout. As soon as it came on I dosed up the Acyclovir and iced it for 2hrs. This stopped the sore in it's tracks. It disappeared completely and I am cold sore free! I can't tell you how relieved I am at how well this medicine works!

acyclovir for Herpes Simplex: I have been taking Acyclovir for almost 2 years now. I believe it to work because I've only had 1 outbreak in the 2 years. I was given the option to take 200mg every 4 hours. (equals 5 a day) for 5 days when an outbreak occurs or to take everyday but I have only taken for the 1 outbreak.
Zovirax (acyclovir) for Herpes Zoster: I've had shingles a total of 6 times because I am immuno-compromised. Each time it was the same area of my back and wrapping around my side to my stomach. I do not recall the first few outbreaks as it was during a time I was so ill that I am basically missing a few months of my life because I was not alert at all during that time. I do recall the last 4 outbreaks. One of the doctors and I have a theory about why I did not notice the burning, itching etc that tends to be very painful and annoying for most people. The meds I am already on. I take pain meds around the clock already as well as taking gabapentin which helps nerve pain. Now on 200mg/day to prevent recurrence. I don't seem to have any issues with medication taken daily.

acyclovir for Herpes Simplex: If you get a cold sore outbreak in your mouth. Don't walk, RUN to the nearest medical practitioner that can give you a prescription of Acyclovir. Usually an outbreak would last me 3 weeks with just using over the counter creams. With the medication, my mouth was back to normal after 4 days.

acyclovir for Mononucleosis: Hope that my information will be read by doctors and the creators of that wonderful and reliable website. I would like to tell, that for me the Acyclovir is sometimes not working while taken as pills, but it ALWAYS works very good, when given in the form of infusions. Of course the doctor must fit the amount of the days when the drips will be given to a patient (it is usually 5-6 days up to 10 days) to the amount of the virus. But it always works - I recovered from the EBV thanks to that five times. I am a proof it always works this way.
acyclovir for Herpes Simplex, Suppression: I was having fever blisters come up about every 6 weeks. I started taking valcyclovir and it would really help speed up the healing process, but I was still getting them about every 6 weeks. The V.A. started me on acyclovir and my outbreaks have been tremendously lessened. When there is an outbreak, I usually only need to take it for 2 days.

acyclovir for Herpes Simplex, Suppression: As long as I am taking it, it works wonderfully. However if I can't afford to get a refill, within ten days I have a flare up. That just tells me that a) I am right to be on suppression therapy, and b) the medicine works.
acyclovir for Herpes Zoster: I had an out break and I let it go for 3 days and I came to know that is SHINGLES My clinic diagnosis confirmed I was adviced to take acyclovir for a period of 10 days (400mg) five times a day. Even though the blisters were out I am getting that shooting pain 4 to 5 times a day a burning sensation and as if I am attacked with 1000 sharp needles in one time and this pain in my skin frustruates me for the last 8 days.
Zovirax (acyclovir) for Herpes Simplex: Zovirax is my first choice for treatment of cold sores which I've had since I was a young girl. Using it in conjunction with Abreva helps promote healing from within the sores; and eliminates the crusty/scabbing that comes with cold sores. Abreva is best used at the first sign of any itching (that familiar feeling of onset) apply as directed on the bottle, and your cold sore will be gone without anyone noticing you even have one. I am just getting over one and with Abreva alone it took three days, no scabbing or crusty formation making it unsightly and causing embarrassment.

This also works for shingles, which can start out as just a little pimple or 2 but you will know by the tingle and then the undeniable relation to how chickenpox feels. Make sure you get it quickly and use at least 10 days or whatever your doctor tells you.
acyclovir for Herpes Simplex: I had my first out vaginal herpes breakout three days ago, and it was the worst thing to ever go through. First I had a yeast infection, then started my period, then I contracted a UTI then I got treated for both yeast infection and UTI. However I went to the emergency room because I had itching extremely bad then my skin began to crack and then ulcer like open sores were there. It was painful to urinate. So the ER doctor treated me with Acyclovir 800 mg 1 tablet 5 times a day, in two days time all my symptoms were wiped out. The only side effect is that my joints ache which is very unusual for me.

Zovirax (acyclovir) for Herpes Simplex: I used to have cold sores all the time when I was a child, either when exposed to too much cold or when exposed to too much heat. Finally, I found a doctor who gave me a prescription (just a few years ago, I'm already an adult) and the Doctor prescribed Zovirax 200 mg 5x a day for 5 days. When I am able to take the medicine as soon as I feel the blister forming, the blister will only last for a day; it will grow and then burst and crust over within twenty four hours, so I've never really had to take the medication for more than 2-3 days. Very thankful for this medicine.
