I would ask for a higher dosage of Abilify. Can't you call your psychiatrist (directly) and have them send a script to your pharmacy? Can you arrange for a GP appointment before that time and does your GP have access to the information the pharmacy has on you and/or would he/she be willing to prescribe an antipsychotic? I wouldn't know how the nurses line works, but if you can get another prescription that's of course fine.

If it's at all possible and you have experience with quetiapine and/or olanzapine, I'd say those would be preferable to aripiprazole (Abilify). Aripiprazole works more like an antidepressant than quetiapine or olanzapine and the latter two are more antihistaminic, which will probably make you sleep. Quetiapine would be preferable to olanzapine because the maximum concentrations are reached more quickly.

But whether it's a good idea to combine that with an intramuscular/depot injection of Abilify, I don't know. It's probably fine, but I don't know if it's easy to figure out which dosage of another (or tablets of the same) antipsychotic you should be prescribed for maximum efficacy.

Is med compliance or convenience the reason you get shots and not tablets? I ask this because in situations like these it might be good to have pills, so you can increase the dose before asking for another prescription.
