Avodart add-on

I was diagnosed with Benign prostatic hyperplasia (BPH) in August of 2006. I have been taking hytrin (terazosin) (80mg) each evening since then.

My wife saw an ad for Avodart (dutasteride) (0.5mg). I googled it then asked my urologist about it. He gave me some samples and a prescription and told me to take it in addition to the hytrin. I have been taking both now for about 2 months.

I don't see any real changes yet, and no side effects that I didn't already have. But I have to wonder about adding another drug. I think I should be taking one or the other, not both. Any comments?
