There is a phenomenon known as viral rebound that gets tossed around at
scientific conferences related to this happening. Its fairly hotly
debated as to what it means.

Yes some people are on it for years. A large scale study followed people
up to 10 years on the drug - that was published in 1995.
This paper is a review of the long term safety issues (the 20 years is the
drug's period clinical use not citing 20 Year continuous use people -
though I imagine there may be a few out there).

Valacyclovir for herpes simplex virus infection: long-term safety and
sustained efficacy after 20 years' experience with acyclovir.
J Infect Dis. 2002 Oct 15;186 Suppl 1:S40-6. Review
THis review summarises long term use of the drug as most frequent rate of
side effects in the first year of around 5% of patients reporting nausea,
Adverse efects after year 1 they describe as follows based on data from
one of Baker's earlier (1995) publications;
"For the rest of the study to year 10, acyclovir continued to be well
tolerated. Adverse events were rare and mild and generally not thought to
be related to treatment. There was no evidence of serious adverse drug
reactions or cumulative toxicity."
So yes, people are on it for years....

Last time I looked most countries had comments inthe prescribing book
to review at regular intervals (be it 6 months or 1 year). I havent
actually looked that up for a few years though. Even if still in place its
just a good idea if you are taking anything long term. Last thing you need
is if you do fall into the wrong side of the stats is to have no safety
net.

To be honest, I don't think I will go on suppressive therapy long term. The
info though is useful in that I'd be more comfortable about taking more and
for longer to prevent outbreaks when I feel one coming on. I'm lucky in that
its worked well for me so far in totally preventing outbreaks and symptoms
once I start taking it.
