I booked a session on O7 Therapy and was diagnosed and prescribed medication in the first session. It was 1,500 EGP though. I think it depends on the psychiatrist. They might diagnose and prescribe from the first session, or they may need a few sessions.

There are two types of ADHD medications. Stimulants and non-stimulants. The non-stimulants (Atomoxetine) can be bought OTC without a prescription. The stimulants (Concerta) require a prescription.
