Can I get an allergic reaction from ritalin (methylphenidate)? My friend gave me one and I am taking an act tomorrow. I am allergic to tree nuts, cats and dogs.

Can I get an allergic reaction from ritalin (methylphenidate)? My friend gave me one and I am taking an act tomorrow. I am allergic to tree nuts, cats and dogs.

It's both illegal &: a bad idea for a person without ADHD to take stimulant medication for the 1st time on the day of a 4 1/2- hour ACT + Writing Test. A low dose may have no positive effect, yet increase blood pressure & pulse & cause anxiety/agitation. Short-acting Ritalin (methylphenidate) wears off in 3 ½ - 4 hours & may cause you to "crash" before you finish the exam. Don't risk your academic future. ...Read more
