Could long-term daily use of adderall (dextroamphetamine and racemic amphetamine) & lamictal (for depression & anxiety) cause a decrease in sexual desire or vaginal dryness or pain? (in females)

Possibly: These drugs may impact sexual function. Adderall (dextroamphetamine and racemic amphetamine) may prolong or prevent orgasm and cause mucous membrane dryness. Lamictal may decrease libido. You and your doctor need to weight these side effects with the benefits you derive from using them. There may be alternative medications you can use, or treatments to counteract these effects if you decide to continue to use them.
