finasteride and many side effects in a short time

I hope this message meets you well!  I’d like to ask a question I’m sure you’ve answered hundreds of times. I greatly appreciate your time. I was recently prescribed finasteride, I have only taken it 3 times at 1.25mg consecutive days, and a week later, 3 more times at ~.7mg, spaced 3-4 days apart. I suffered from side effects (low libido, terrible brain fog, difficulty getting erection, and difficulty maintaining one) during this time. I’d like to continue the drug but I’m scared, honestly. Is it likely these side effects will disappear?

For the record, I’m 24, 200lbs 9% body fat and in good shape. I don’t take any other medication. I use minoxidil, I take biotin, and today I purchased zinc. Thank you again for your time, and for your help!

Sound like the drug and you are not good for each other. I would stop the medication
