Shingles during colitis flare
Date: 9/24/2016
I got shingles during a mild colitis flare. Was pdescribed 800mg acyclovir 5x a day for 7 days. The flare was resolving but am now experiencing constipation with mild cramping more mucous in stool. Side effect or just colitis? Acyclovir ok during colitis flare?


AskDocWeb: Constipation is not one of the listed possible side effects of Acyclovir. One of the causes of constipation is not drinking enouth water. Your body needs water to keep the stools soft and get them out of the body.

This drug really helps With shingles.


Thyroid nodules?
Date: 12/18/2016
Is there a correlation between having thyroid nodules and taking oral acyclovir?


AskDocWeb: Not that we have seen. There are several conditions that can cause nodules to develop in a thyroid gland:

  • Chronic inflammation of the thyroid (thyroiditis)
  • Iodine deficiency
  • Multinodular goiter
  • Overgrowth of normal thyroid tissue; thyroid adenoma
  • Thyroid cancer
  • Thyroid cyst (usually benign)

Salt water gargles 3 to 4 times per day regularly will provide symptom relief for some.

Side effects

How long does the side effects last after stop taking Acyclovir? After taking two doses yesterday I feel extremely weak and disoriented. When I do get up my body feels very weak and light headed. I also have nausea, loss of appetite, headache, drymouth and restlessness. My doctor told me to stop using it. ThNks


AskDocWeb: The half-life of Acyclovir is about 3 hours. That’s the amount of time it takes for half the drug to leave your system. If you have a healthy functioning elimination system your body will clear it to the point where it no longer has an effect within 15 hours.

Sharing with readers
Date: 2/5/2017
I have had a few different outbreaks over the last few years. Shingles. Cold sores. I am a 38 year old female. I take 200 or 400 milligrams 5 times a day when I have outbreaks. I’d like to share with the other readers that after outbreaks, when everything is cleared up, I saw her up to 10 days very heavy and unpleasant itchiness all over my body. I see sometimes all over different internet sites that this is common, yet here I saw that the doctor answers this has nothing to do with the virus or the treatment, it seems to be a difference disease. From my experience, herpes and post herpes itchiness come together. On a different matter, lately I’ve been wondering, if I should be putting zovirax cream on my lips every morning as a preventative measure. Is there any reason not to? Thanks!


I started to get tremors
Date: 2/23/2017
I started taking Acyclovir and 2 weeks into taking I started to get tremors. I immediately stopped and it took about 4 days for the tremors to stop. I don’t get outbreaks but I have bad neuropathy and digestive issues. It cleared up the digestive issues and stopped the neuropathy. Within a week of stopping the medication the neuropathy was back. So I started taking it again and exactly 2 weeks into taking I started getting muscle jerks so I immediately stopped it. It’s been a week and I still have muscle jerks. Trying to fall asleep is awful as I jerks about 4 timeso before finally falling asleep. I can feel the jerks when I try to move certain parts of my body. Is this a side effect? Since valcyclovir turns into acyclovir in the body would I get side effects from it too?


Pre mensturation
Date: 5/2/2017
I had acyclovir 800mg *3 times a day for 5 days for herpes Libia. I had slept more den usual. But d most important side effect to mention nd which I didn’t found on d side effects mentioned on wiki for acyclovir was an tooo early mensturation . When my periods end ( I have 5 day bleeding cycle)… exactly after 6 days(clean;no bleeding) I got periods back bleeding nd pain. I don’t understand this … I’m almost 28 nd dis has never happened to me in my life. Years back my uncle who was father figure to me died nd only den I suffered pre mensturation 10 days before my cycle starts … I can understand dat I was sooo much in pain nd stress… but dis tym almost 22 days early … how come??? … I had no stress nothing…

Acyclovir for cold sores
Date: 7/18/2017
I had shingles on my trigeminal nerve in the face/eye. I use acyclovir for cold sores. I was advised by a doc to take 400mg in morning and at night to prevent an outbreak. When I take acyclovir consistently as prescribed, I have terrible tendonitis after a few weeks. I don’t know what the connection is, because I doubted it the first time two times it happened. This last time was miserable. It was hard to figure out because I am very active, and it takes a few weeks before I feel it.


Prevent stress breakouts
Date: 7/28/2017
I have recently started taking this product has a temporary suppressive form of therapy knowing that I would be highly stressed for about 2 months ish time with life events. Typically I don’t need to take it all so this was just a solution to prevent stress breakouts. Toward the end of this last month I’ve noticed my hair thinning. Is this a common reaction ? Maybe it was both stress and the drug I’m not sure but I’m hoping it stops once it’s all out of my system.


Knocked it out
Date: 8/30/2017
I took Acyclovir, 800mg, twice a day for seven days for an inner ear virus and it knocked it out. The dr. did not prescribe it, but after researching the problem on the internet, I took it on my own. I was told that it probably will come back.
