(NOTE: For conducting pregnancy tests, the investigator has the option of determining the sexual maturity all girls 8 years of age and older.) Acceptable methods of birth control include: barrier method with spermicide; steroidal contraceptive (eg, oral, transdermal, implanted, and injected) in conjunction with a barrier method; intrauterine device (IUD); or abstinence

* use of any MAO inhibitors or SSRIs within 2 weeks of the baseline visit
* hypertension, defined as follows (SBP = systolic blood pressure and DBP = diastolic blood pressure):
* ages 6-9 years SBP \> 122mmHg or DBP\>78mmHg
* ages 10-12 years SBP \> 126mmHg or DBP\>82mmHg
* ages 13-17 years SBP \> 136mmHg or DBP\>86mmHg
