6.Female subjects of child-bearing potential must agree to use an acceptable form of contraception (e.g., prescription oral contraceptives, contraceptive injections, intrauterine device, double-barrier method, contraceptive patch, male partner sterilisation) before entry and throughout the study, and must have a negative urine pregnancy test at screening.
7.Informed Consent Form signed by the subject.
8.Subject agrees to take only the supplied study drug as treatment for ADHD during the study.
9.Subject agrees not to initiate a new behavioural modification programme during the study or if currently using a behavioural modification programme and agrees not to change this programme during the study.
10.Subject is able to comply with the study visit schedule and willing and able to complete the protocol-specified assessments.
11.Healthy on the basis of a physical examination, medical history, anamnesis, and the results of blood biochemistry or haematology tests. If the results of the biochemistry or haematology tests are not within the laboratory's normal reference ranges, the subject may be included if the investigator considers the deviations are not clinically relevant. This should be clearly recorded in the subject's source documents and the Trial Manager informed.

1.Known to be a non-responder to methylphenidate, or subject has a child known to be a non-responder to methylphenidate.
2.Has been treated with any methylphenidate-containing medication within 1 month of screening visit. One month is considered a reasonable time for patients treated with methylphenidate to return to a disease status baseline.

16.Use of monoamine oxidase inhibitors, except if tapering off, within 4 weeks of the baseline visit.
17.Use of other anti-depressants (unless subject has been on a stable dosage for at least 3 months prior to screening, in which case treatment may continue so long as dosage remains unchanged for the duration of the study) or mood stabilisers (e.g. anti-epileptics, lithium), except if tapering off, within 2 weeks of the baseline visit (for fluoxetine within 4 weeks). Any medication likely to interfere with safe administration of methylphenidate.
