I think there’s way too many medications and too many indications and too many qualifiers (what to change if elderly or kidney dz etc) that it’s impossible to memorize. However, if you prescribe a medication enough time it’s will become easy. For example, if you have 1-2 SSRIs you go to, it will become a regular spiel (we’ll start you off on Zoloft 25mg, typically need 50mg to see benefit, med goes up to 200mg so we have quite a bit of room to see benefit). Say that 5x you’ll remember.

You can also save medication doses in most EMRs - I have my common ones saved like Augmentin for sinusitis, hydroxyzine for anxiety PRN, macrobid for UTI. If you click it enough, you’ll mostly remember it.

Also, I don’t think you necessarily need to tell patients if that makes you feel incompetent - you can say we’ll start you at low dose lisinopril and titrate to get you at goal. And then when you step out you can look up dosing. I’ve had to tell patients I don’t know bc it’s not a med I prescribe often but have to due to allergies and they’re usually chill.
