Rash, dry mouth, muscle aches, seizure, agitation. These are the most common side effects. IsThisIt isn't wrong at all: it's on you to understand your medication, to know what to do if you miss a dose/take double, how to best stop it (with your doctor's help). No one else is going to keep your personal information for you. I'd recommend a medical ID tag or wallet card.
The important thing is, you need to keep taking this medication. If it's having an adverse episode, let your professional know this. He/she can help you step down. I'm going take a stab and guess your diagnosis is in the psychotic family. People with associated conditions under this category are notorious for poor medication compliance, reason being we're generally talking some advanced chemicals here. It's really, truly important you take your meds regularly, even if you're feeling great. But I'm sure you're on top of stuff.
If you have any symptoms not listed above, talk to your doctor about what might be causing them. Good luck.
