Can I take 1mg and Adderall together?

Drug interaction guide

Combining Xanax (alprazolam) and Adderall (amphetamine salts) is common but requires caution because they have opposite effects on your body. Adderall is a stimulant that speeds up your heart rate and brain activity, while Xanax is a sedative that slows them down. This 'tug-of-war' can mask the effects of either drug, potentially leading you to take too much of one or the other. It can also put extra strain on your heart and nervous system.

Why this happens

Adderall increases the levels of chemicals like dopamine and norepinephrine in the brain to increase alertness. Xanax works by boosting a chemical called GABA to calm the brain. Because they work in opposite ways (pharmacodynamic antagonism), they can hide the signs that you have taken too much of either medication.

You should only take these two medications together if they have both been prescribed by the same doctor who is aware of your full treatment plan. Do not change your doses or timing without medical advice. Be aware that Xanax may make you feel less 'alert' from the Adderall, and Adderall may make you feel less 'relaxed' from the Xanax. Avoid alcohol entirely when taking this combination, as it significantly increases the risk of dangerous breathing problems and extreme drowsiness.
