Alibaba2013,
I am surprised your ENT did not put you on a course of Prednisone and Valtrex. From my understanding, this has become fairly standard treatment for patients whose tinnitus might be related to a viral infection. Because my ENT could not pin-point the cause of my tinnitus definitively, I was given this course. She stressed it was a bit of a shot in the dark, and told me that these meds in combination are probably most likely to be effective in the first few weeks after onset. She was the second ENT I saw after my tinnitus appeared, so I was not prescribed these medications until nearly 2 months after onset. I cannot say that it helped my tinnitus, but if I had to do things over again, I would still opt for these medications, preferably just sooner. FYI, Prednisone can have pronounced side effects for some individuals. I experienced some sleeplessness and agitation, but otherwise I did fine. The dosage should be tapered over time. I only mention this because a poster on another board claimed the dosage he had been prescribed was not tapered, and going from a high dose to none is really not a good idea when taking a steroidal medication.
I would ask your doctor why he does not believe Valtrex will help fight the virus, particularly when he does not know what type of virus you have (or if you have one at all). Granted, Valtrex is mostly prescribed for herpes suppression and shingles, but I see no reason why Valtrex would not offer a measure of suppression regardless of what type of virus you have. Again, it is not uncommon for ENTs to prescribe it along with Prednisone for tinnitus thought to be caused by a virus, so Valtrex must be thought to offer some general anti-viral benefit. Therefore, I see no reason why he is not prescribing it to you, especially since the side effects and risks of taking a short course of Valtrex are quite low. If you do get these scripts, just be prepared to pay an arm and a leg for the Valtrex. Even with my co-pay, it was VERY expensive. There are now several generic versions available, but some doctors and patients claim these do not work as well. If you google "Valtrex versus generic," you can read a lot of opinions about this. Good luck!!
