Amphetamines

Amphetamines are stimulants that speed up the messages between the brain and body. Some amphetamines such as dextroamphetamine (Adderall XR, Dexedrine Spansule) are prescribed to treat medical conditions such as attention-deficit/hyperactivity disorder (ADHD), narcolepsy and depression. Other amphetamines are illegal and highly addictive. This includes methamphetamine, also known as meth.

Meth should not be used while breastfeeding. Meth crosses into breast milk and can stay for more than four days after use. If you are breastfeeding, you should regularly test your urine to make sure the meth is no longer in your system. Breastfeeding should be delayed until 24 hours after a negative urine test.

Some studies have shown that prescribed amphetamine medicines when used at the right dosages do not have negative effects on breastfed infants. Your healthcare professional may recommend additional monitoring of the baby for symptoms of irritability or poor feeding. The long-term effects of amphetamine exposure on infant development are not well understood. If needed, methylphenidate (Ritalin, Concerta) may be the safest option to take for ADHD while breastfeeding.

Some studies report that amphetamines may decrease a hormone in the mother's body called prolactin. A decrease in prolactin may reduce the amount of breast milk produced. This may be more of a concern if you are taking higher doses of medicine or if you are just beginning to breastfeed. Talk with your healthcare professional about any concerns if you're taking a prescription amphetamine.
