التداخل بين ديكستروأمفيتامين وغوانفاسين

In these cases, high-dosage guanfacine was discontinued; concomitant stimulant use was also reported, which may potentially increase hypertensive response upon abrupt discontinuation of guanfacine.

If abrupt discontinuation occurs (especially with concomitant stimulant use), patients should be closely followed for rebound hypertension.

Antihistamines Amphetamines may counteract the sedative effect of antihistamines.

Antihypertensives Amphetamines may antagonize the hypotensive effects of antihypertensives.
