I can provide some general information that might help you understand the situation.
Adderall is a prescription medication used to treat attention deficit hyperactivity disorder (ADHD) and narcolepsy. It contains a combination of amphetamine and dextroamphetamine salts. Adderall is available in both brand-name and generic versions, and different pharmaceutical companies can manufacture the generic versions.
Teva and Lannett are both pharmaceutical companies that have been known to manufacture generic versions of Adderall. When a medication is prescribed, the pharmacy may dispense the generic version produced by the company that currently has the contract to supply the medication. The active ingredients in generic medications are required by law to be the same as those in the brand-name version, and they must undergo rigorous testing to ensure their safety and effectiveness.
In theory, generic medications should be just as effective as their brand-name counterparts because they contain the same active ingredients in the same amounts. However, some people may respond differently to different generic versions due to the inactive ingredients or other factors, which is known as the "generic drug substitution" issue.
If you notice any changes in how your medication affects you or have concerns about the switch between Teva and Lannett generic Adderall, it's essential to discuss these concerns with your prescribing doctor or pharmacist. They can provide specific insights and guidance tailored to your situation.
Please note that the best course of action would be to consult a healthcare professional for advice regarding your specific medication and any changes in its manufacturer or formulation.
