Adderall is a medication used to treat attention deficit hyperactivity disorder and narcolepsy. It stimulates your central nervous system, affecting the chemicals in your nerves and brain that affect your impulse control and hyperactivity. Adderall interacts with a number of medications, including antacids containing calcium carbonate.

Calcium Carbonate

Calcium carbonate is one of the less expensive forms of supplemental calcium, and it contains a relatively high amount of elemental calcium. It is commonly used in antacids to help reduce the amount of acid in your stomach since it uses some stomach acid for absorption. Two examples of antacids that contain calcium carbonate are Tums and Rolaids.

Adderall and Calcium Interaction

If you take large amounts of antacids that contain calcium carbonate, this can increase the amount of adderall in your body, possibly causing dangerous side effects. However, taking an antacid occasionally should be safe, according to eMedTV. If you take these antacids regularly, let your doctor know, as you may need to have your adderall dosage adjusted.


Certain health conditions make it unsafe to take adderall. These include high blood pressure, hardening of the arteries, glaucoma, heart disease, anxiety and history of addiction to alcohol or drugs. Adderall can cause side effects that include insomnia, dizziness, headache, constipation, diarrhea, irregular heartbeats, weight loss, impotence, dry mouth, increased blood pressure and fainting.


Don't take adderall with vitamin C or fruit juice, because this can make it less effective. Only take adderall as directed by your doctor, and do not suddenly stop using adderall . Adderall is a combination of amphetamine and dextroamphetamine, and as such can be habit forming. Tell your doctor about any medications you take to make sure that adderall will not interact with any of them and cause serious side effects.
