Patient discussion about host

Q. I was diagnosed with depression and have taken a whole host of antidepressants. I’m Mark, 29 years old male. I was diagnosed with depression and have taken a whole host of antidepressants. My eyes are extremely blurry, I’m worrying about that. Does this side effect go away with time, or is it permanent while on medications?

A. Mark, you really need to consult your doctor. I hope you're not relying totally on the Internet for medical advice. Side effects are common with most drugs, and some are more tolerable than others. "Extremely blurry" eyes seems like it could affect your driving, as cbellh47 wrote, but many other things as well.

Sometimes it does take many, many attempts to discover an anti-depressant or a combination of more than one to achieve a better mood balance. We're all chemically different and react to drugs differently. There's many options and I had to endure years of experimentation before I was satisfied, but I now have the rest of my life to appreciate what I went through.

I also used the help of different doctors and psychiatrists, as well as self-learning. If your doctor doesn't seem to be beneficial, consider asking him/her to recommend a specialist. New treatments come to light regularly and not all docotrs are wise to them.
