Re: 19 year old on cipralex, Couldnt get it up one time...
Loss of libido is definitely a side effect of medication. ED can occur as a result of low libido or can happen on its own due to anxiety/depression recurring. In someone of your age it's likely to be one of these factors rather than something irreversible like organic disease, so I wouldn't worry about it too much.
Meds can also make you put on weight but as Sandy said, I would speak to your doctor about trying another med that may suit you better. Be careful about suddenly stopping. Make sure your doctor is happy for you to do this and that you gradually taper it if you do decide to stop.
