- Whether to continue a stimulant ADHD medication in pregnancy is a highly individual decision to make with the prescriber and your OB or maternal-fetal-medicine specialist.
- MotherToBaby reports that studies of people taking dextroamphetamine-amphetamine as prescribed have not shown an increased chance of birth defects.
- Some studies have linked prescribed use to higher blood pressure and preeclampsia, though ADHD itself may also raise the chance of some pregnancy complications.
- Findings on preterm birth and growth are mixed; misuse or higher-than-prescribed doses appear to carry more risk than prescribed use.
- Withdrawal has not been reported in newborns of people who take the medication as prescribed, though misuse can cause temporary newborn symptoms.
- The old FDA A/B/C/D/X letter categories are retired; never start or stop this medicine on your own, and bring the decision to your clinician.
If you take a stimulant for attention-deficit/hyperactivity disorder (ADHD) and you are pregnant or planning to be, you may be weighing two worries at once: how the medicine could affect the baby, and how you will manage if you stop. Both sides matter. This article gathers what a leading U.S. information service reports so you can have a more informed conversation with the prescriber and the clinician who manages your pregnancy. It is general education only and is not a substitute for that conversation.
What this medicine is and what it treats
The medicine commonly sold under the brand name discussed here combines two closely related stimulants, dextroamphetamine and amphetamine. It is prescribed mainly to treat ADHD and, in some cases, a sleep disorder called narcolepsy. Stimulants like these affect chemical messengers in the brain that influence attention, focus, and impulse control. Because ADHD is a long-term condition, many people are already taking this medicine when they become pregnant, which makes the “continue or not” question a real and common one.
What the guidance says about pregnancy
MotherToBaby, a service of the non-profit Organization of Teratology Information Specialists, has reviewed the research on dextroamphetamine-amphetamine in pregnancy. Its summary is nuanced rather than a simple yes or no.
Birth defects
MotherToBaby reports that studies of people who take dextroamphetamine-amphetamine as prescribed have not shown an increased chance of birth defects. A large study of people taking stimulants for ADHD during pregnancy likewise did not report an increased risk of birth defects. This is generally reassuring, while keeping in mind that no medicine can be called risk-free.
Miscarriage, preterm birth, and growth
On miscarriage, MotherToBaby describes the evidence as mixed: studies of pregnancies exposed to prescribed amphetamines have not shown a consistent increase in miscarriage, with some reporting a small increase and others finding no clear difference once maternal ADHD and other factors are taken into account. Findings on preterm birth and on the baby’s growth are similarly mixed, with some studies suggesting a higher chance of early delivery or poorer growth and others not. MotherToBaby notes that misuse, meaning higher doses or use that is not prescribed, carries greater risk than taking the medicine as prescribed.
Blood pressure and preeclampsia
Some studies have found a higher chance of high blood pressure and preeclampsia (high blood pressure with signs of organ involvement, such as effects on the kidneys) in pregnant people taking this medicine. At the same time, MotherToBaby points out that ADHD itself may raise the chance of some of these complications, which makes it hard to separate the medicine from the condition it treats. This is one reason blood pressure is watched closely during pregnancy.
Newborn effects
MotherToBaby reports that withdrawal has not been reported in the newborns of people who take dextroamphetamine-amphetamine as prescribed. It notes that misuse can cause temporary newborn symptoms such as jitteriness and breathing difficulty. A study of more than 7,000 pregnancies in which the medicine was prescribed in the second half of pregnancy did not find an increased chance of neurodevelopmental conditions, including autism and ADHD, in the children.
The other side: untreated ADHD also matters
Deciding about a stimulant in pregnancy is not simply a matter of “less medicine is safer.” Untreated ADHD can affect daily functioning, safety, mood, and the ability to manage a pregnancy and a household, and MotherToBaby notes that untreated conditions may themselves raise the chance of some pregnancy complications. For some people, stopping is the right call; for others, the risks of going untreated outweigh the uncertainties of the medicine. That balance is personal, which is exactly why it belongs in a conversation with your clinician rather than being decided alone.
Breastfeeding
MotherToBaby describes the breastfeeding data as limited. Product labels advise against use while breastfeeding, but small studies have not found health problems in the nursing infants studied. Because the picture is not fully settled, MotherToBaby recommends discussing the individual benefits and risks with your healthcare providers rather than deciding from a label alone.
A note on the old FDA letter categories
Older leaflets and web pages sometimes assign medicines a pregnancy “letter category” such as C. The U.S. Food and Drug Administration retired that A/B/C/D/X letter system, replacing it with narrative labeling under the Pregnancy and Lactation Labeling Rule that describes what the data actually show. A letter grade you find online is not current guidance and is no substitute for a discussion with your clinician.
Do not start or stop on your own
If you are taking this medicine, do not stop, lower, or change it on your own the moment you see a positive test. A sudden stop can affect mood, focus, and functioning, and the safest path is to review the plan with the prescriber, ideally alongside your OB. Equally, do not start or increase a stimulant during pregnancy without medical guidance. The right answer is individualized, and it can change as pregnancy progresses.
When to call your OB or a specialist
Talk with your prescriber and obstetric provider as early as possible if you are pregnant or planning to be. Reach out promptly for headaches, vision changes, swelling, or high blood pressure readings, which can be signs of preeclampsia, or for any concern about the baby’s movements later in pregnancy. If your situation is complex, your provider may involve a maternal-fetal-medicine specialist. For questions about a specific medication exposure, you can also call MotherToBaby at 1-866-626-6847, a free service that answers questions about medicines and other exposures in pregnancy and breastfeeding.
Frequently asked questions
Is this stimulant safe to take while pregnant? MotherToBaby reports that prescribed use has not been shown to increase the chance of birth defects, but other findings, such as on blood pressure and preterm birth, are mixed. Whether to continue is a decision to make with your clinician for your situation.
I took it before I knew I was pregnant. Should I worry? Try not to panic. Much of the prescribed-use data reviewed by MotherToBaby has been reassuring on birth defects. Let your OB and prescriber know what you took and when, and ask any follow-up questions there or through MotherToBaby.
Will my baby have withdrawal if I keep taking it? MotherToBaby reports that withdrawal has not been described in newborns when the medicine is taken as prescribed. Temporary newborn symptoms have been linked to misuse, which is another reason to take it only as directed.
Should I just stop to be safe? Not on your own. Untreated ADHD carries its own risks, and stopping suddenly can affect your functioning. Bring the question to your prescriber and OB so you can weigh both sides together.
Can I breastfeed while taking it? The data are limited, and labels advise against it, though small studies have not found problems in the infants studied. MotherToBaby recommends deciding with your provider based on your individual situation.
Does ADHD itself affect the pregnancy? MotherToBaby notes that untreated conditions may raise the chance of some complications, and that ADHD itself may contribute to outcomes like higher blood pressure, which makes the medicine hard to separate from the condition. Your clinician can help weigh this.
This article is general education, not medical advice, and must not be used to start, stop, adjust, or taper any medication on your own. Suddenly stopping some medicines can be dangerous. Always work with the prescriber who manages your care. In an emergency call 911; for mental-health crisis call or text 988.
