Valacyclovir prescribing information
Common Questions and Answers about Valacyclovir prescribing information
valtrex
Acyclovir (Zovirax) and famciclovir (Famvir) are similarly nontoxic. The official prescribing information for valacyclovir indicates a 1% chance of minor abnormalities of liver function in people taking valacyclovir, which was slightly higher than 0.5% for placebo. That difference was not statistically significant and there is no suggestion even for routine liver tests in people taking the drug.
I'm not sure that I understand your response.
1. I think that you meant to say that "experience tells us that when people ?quit? taking the valacyclovir, they sometimes do have an outbreak soon after that." This is my concern, that the valacyclovir takes over and that the body's immune response is less engaged in fighting the infection. Do you see what I mean?
2.
Valtrex is an acyclovir prodrug. Greatly simplified - you swallow valtrex and your body converts it into acyclovir inside the body. You get more active acyclovir available to kick a little herpes butt by doing it this way. That's why you take valtrex less often. We don't have studies to confirm that acyclovir reduces transmission the same amount as valtrex does but we assume it does.

I have read that Valtrex and Valacyclovir can be used for the suppression of herpes , does that hold true for Valcivir also,, isn't Valacyclovir the generic of Valciver ,, if yes what is the usual dosage for the suppression of the virus?
As such I contacted my doctor and was prescribed valacyclovir hcl which I took (2 1 gram tablets twice daily). The cold sore remained small and eventually went away. After this I went 1-2 days without taking any Lysine or valacyclovir and on the second day I noticed the cold sore coming back again and now appears to have come back and crusted over. I did not think the new cold sore was actually one but then it crusted over.

"Clinically symptomatic HSV-2 infection developed in 4 of 743 susceptible partners who were given valacyclovir, as compared with 16 of 741 who were given placebo (hazard ratio, 0.25; 95 percent confidence interval, 0.08 to 0.75; P=0.008).
Just looking for anymore information or advise about withdraws from Fioricet / I have been taking this medication from years from Migrain headaches, it's seemed the longer I was on it the less it helped so I would increase my doses because I could not get rid of my headaches the other day I just stopped using it because it was like just this non stop headache.
I talk valacyclovir for herpes out breaks I have a high dosage one for when I get them it doesn't harm the baby.
Though this is my first pregnancy and I'm 7 weeks.
They told me once I get closer to my due date to take them daily so there is no break out.
t want it there so I started to take Valacyclovir it would keep breaking out every month or so I went on a daily maintenance of 500mg a day. When ever I would miss a pill I start feeling the sensation which I felt when I was going to get an outbreak. I would keep taking it for 5 years. I wanted to stop taking it so I had read some Medical Article's online that Valtrex can rebound.
So I had a swab test taken on cuts that are on my butt and vagina and I tested positive for type 1 herpes 2 weeks ago. I was prescribed valacyclovir and I have been taking this twice a day everyday for the past 2 weeks and it has not helped me at all. I am in so much pain and I don't understand why I am still not healing or getting better. I just got my period and I am so sore on my vagina and bottom there are several bleeding cuts on my vagina and between my butt and vagina.
The information you all have provided here is greatly appreciated and not to mention very informative. I'm working on learning everything I can to help two people actually. They're a couple so it's very hard. But I know there are problems with addiction for both of them. I figure the more knowledge I have the more prepared I will be. I have one of them willing to talk to me tonight. He knows what I'm going to be talking about and I'm so surprised he said ok...
And although recurrent outbreaks can occur while taking valacyclovir, they are rare -- and monthly is unheard of. It is possible your HSV has become resistant to the drug, but that's quite rare as well.
As for valacyclovir side effects, you needn't worry.
I will do my best to answer your questions but in general, many of these questions and information about herpes can be obtained by accessing excellent informational web sites such as the one run by the American Social Health Association (disclosure, Dr. Handsfield and I are both on the Board of Directors of ASHA).
Once a person has herpes the infection is chronic. In some people the infection will cause occasional clinical recurrences and in others it will not.
I am 18 years old and was Diagnosed with Shingles on June 22nd after noticing the rash on my back. Since I started taking valacyclovir 3 times a day at 500mg my Shingles has started to get better and clear up. However just today I have started to get a new more painful (Then my initial Shingles) feeling of burning on my right side just around my armpit. Is it normal for new a new rash to start when I have been consistently taking the anti virals? Should I go see my doctor again about this?
m getting mixed messages in eagards to Valtrex dosages during an outbreak. I currently take 500 mg of Valacyclovir daily as a suppressant. But I am still having outbreaks. When having one do I increase my dosage? I asked my doctor and she said no since it was already in my system just continue taking the 500mg daily.
Also it seems since I've gotten the diagnosis, that I'm having more outbreaks, could it be I need a stronger daily dosage for suppression?
I was diagnosed with Herpes 33 years ago and have been using 1000 mg Valacyclovir a day for the past 4 years and have been free of outbreaks until a few weeks ago when I lost my job and became quite stressed.
I was able to take one extra tablet of 500 mg which stopped the outbreak from turning into blisters, but I am concerned if this medication is not working for me anymore.
I also wonder if Valacyclovir is the same as Valtrex or if Valtrex is stronger?
I appreciate your help.
I'm on daily 1 gram valacyclovir for suppressive therapy. I can feel a new outbreak coming. Would it help if a take the valacyclovir twice daily for a couple of days to help with the OB?
) the infected person should take suppressive therapy with an antiviral medication such as acyclovir or valacyclovir. While all 3 available antiviral medications are likely to work since their mechanisms of action is the same, only valacyclovir has been studied for this purpose and therefore can be considered to be "proven" for this purpose. Daily suppressive therapy will reduce recurrences, reduce asymptomatic shedding of the virus and reduce transmission.
A month ago I had protected sex, using a condom. Already the same day I felt some burning when urinating. Over the following few days the burning increased and spread. My genital area started itching and tingling and I also started feeling some pain in my left foot. My upper lip was also tingling on the left side. I did a lot of reading about STI:s and found HSV-2 to be the most likely diagnosis...
There should be a prescribing information sheet included with a prescription medicine that will list known side effects.
In preparing to address your questions I re-read your initial interaction with Dr. Handsfield, as well as our exchange last September. I still think that you need more information. As Dr. Handsfield and I have pointed out to you, your blood test result was on the low side to be confident in the diagnosis. We both suggested you get a culture of PCR test from an outbreak when it occurs. Have you done this.
What are the contraindications of taking penicillin and valacyclovir during the same cycle ? Can they both be taken on the same day ?
