Next section is "Medicine" where you can register all the medicines you will use. Click on the "+" icon located in the upper right corner of the table and fill in the information of the medicine.
Following section is "Treatment plan" where with the causes and the medicines you had previously registered you can register different treatment plans indicating what's the cause, what medicine to use for that cause, amount of that medicine to use, how many days will the treatment last and the withdrawal days for that specific plan.
