If i am diagnosed with adult adhd what would a doctor most likely try first as far as treatment goes? is there a specific medication doctors usually go to first?

Adult adhd: Not really. Depends on the doctor's experience with other similar cases & their comfort level.

Therapy & Meds: Complete and accurate diagnosis is essential, since other underlying conditions, such as trauma, can look like adhd. Refer to a psychologist for a skill evaluation and diagnosis. Refer to mental health professional for skill building in areas such as organization and concentration. Refer to psychiatrist for meds. Have coordination among all providers, especially on potential substance abuse.

Same as for kids: The main treatment options for adults with adhd are the same as for kids with adhd. As far as prescription meds, generally a stimulant (e.g. Adderall, vyvanse, (lisdexamfetamine) ritalin) or strattera are first-line treatment options.

Yes: The standard of care recommends using a stimulant medication on first pass through. That would be a methylphenidate or amphetamine derivative. If this is not effective then a look for comorbidities would be the next step.
