If you're taking Sunosi and wondering what it can safely mix withother meds, supplements, alcoholhere's the quick version: some combos are fine, some can nudge your blood pressure and heart rate up, and a few are firm "nope." You deserve a clear map, not a guessing game.
Below, we'll walk through what to watch for, when to avoid Sunosi, and how to chat with your doctor about safer alternatives. No scare tacticsjust honest, practical guidance so you can feel confident and in control.
What Sunosi is
Why interactions matter
Sunosi (solriamfetol) is a wake-promoting agent. Think of it as a focused nudge to your brain's alertness systems. That nudge can also push up blood pressure (BP) and heart rate (HR). So when you add in other things that do similar nudginglike stimulants, certain antidepressants, or even a strong cup of cold brewthe effect can stack. That's why Sunosi interactions deserve a quick, thoughtful look.
How solriamfetol worksquick and clear
Solriamfetol primarily increases levels of dopamine and norepinephrine in the brain. Those are your alertness and motivation messengers. Helpful for sleepiness, yes, but they can also narrow blood vessels and boost heart rate. Translation: the same mechanism that lifts your energy can, in some people, raise BP/HR.
Who typically takes it
Sunosi is prescribed for excessive daytime sleepiness due to narcolepsy or obstructive sleep apnea (OSA). Many folks with these conditions also take other medicationsantidepressants, antihypertensives, allergy medswhich is why understanding Sunosi drug interactions matters.
Key drug risks
BP and HR add-ons
These medications can layer on stimulation or affect blood vessels, increasing the chance of elevated BP/HR, jitteriness, headaches, or palpitations.
Examples to flag
Common culprits include stimulants (amphetamine, dextroamphetamine, lisdexamfetamine, methylphenidate), SNRIs (venlafaxine, duloxetine, desvenlafaxine), bupropion, MAOIs (contraindicated within 14 days), decongestants (pseudoephedrine, phenylephrine), and some migraine triptans. Not everyone reacts, but this is where you stay alert.
What to ask your doctor
Bring a short list: your current dose, other meds and supplements, and any symptoms (headache, racing heart, anxiety, poor sleep). Ask about dose timing, whether a lower dose makes sense, and a monitoring plan for BP/HR for the first few weeks or when anything changes.
MAOIshard stop
Why this combo is risky
MAOIs plus Sunosi can dangerously elevate norepinephrine, risking severe hypertension and, in extreme cases, hypertensive crisis. This is a true "avoid."
Washout guidance
Do not take Sunosi within 14 days of stopping an MAOI. If you're unsure whether something is an MAOI, ask your pharmacist or prescriber before starting Sunosi.
Antihypertensives
Could it blunt your BP control?
Sunosi can push BP upward, which may counteract your BP meds. The fix is usually practical: check BP at home for 12 weeks after starting or changing your dose. If readings creep up (e.g., consistently above your target), call your clinician. They might adjust timing, tweak doses, or switch therapies.
Psych meds and sleep
SSRIs/SNRIs/bupropionwhat to watch
These can add to activation: anxiety, restlessness, jitteriness, or trouble sleeping. This doesn't mean they're unsafe together; many people use them successfully. It just means be observant, start low, and dose Sunosi early in the day to protect sleep.
CYP or transporters
Metabolism notes and kidneys
Sunosi is minimally processed by liver CYP enzymes and is largely excreted unchanged in urine. That's good news for many drug interactions, but it makes kidney function important for dosing. If your eGFR is reduced, your prescriber will likely adjust your dose.
Alcohol choices
Can you drink?
Short answer: sometimes, with care. Alcohol can worsen sleep, make you groggier the next day, and at higher amounts may swing BP/HR, especially combined with a stimulant-like medication. If you're testing the waters, keep it modest and track how you feel.
Potential effects to expect
Worsened sleep quality, faster heart rate, occasional headache, and off-balance judgmentespecially if you drink late or more than a standard drink or two. If Sunosi boosts your alertness but alcohol drags your system the other way, your body can feel tugged in both directions.
If you choose to drink
Try spacing: take Sunosi early morning; if you drink, keep it light and earlier in the evening. Consider a personal limit of 1 standard drink (women) or up to 2 (men), and skip entirely if you notice BP spikes, palpitations, or anxiety. If sleep is fragile, alcohol usually isn't your friend.
Who should skip alcohol
Better safe than sorry
If you have uncontrolled hypertension, arrhythmias, significant anxiety or insomnia, or a history of substance use disorder, avoiding alcohol while on Sunosi is a smart, caring choice for yourself.
Supplements guide
Caffeine and boosters
Additive stimulation is real
Caffeine adds to Sunosi's alertness. That can be helpfuluntil it isn't. Cap total caffeine around 200300 mg/day at first, and track symptoms. Watch hidden sources: pre-workout mixes, green tea extract, guarana, energy shots. One strong afternoon coffee can undo your night's sleep.
Herbal stimulants
Products to approach carefully
Yohimbine, bitter orange/synephrine, guarana, and some ginseng products can raise BP/HR and spike anxiety. If you're on Sunosi, stacking these is like stepping on the gas twice. If you insist on trying something, start tiny, log your vitals, and have a clear stop rule.
Sleep and calming aids
Melatonin, magnesium, L-theanine
These can be reasonable supports when timed right. Melatonin 0.53 mg about 12 hours before bed, magnesium glycinate at night if your gut tolerates it, and L-theanine 100200 mg in early evening can smooth the edges. Just avoid taking them so late that you feel foggy the next morning.
Nootropic "stacks"
What's theorized vs. known
Alpha-GPC, L-tyrosine, rhodiolainteresting ideas, limited data with Sunosi. L-tyrosine may add to catecholamines; rhodiola can be activating. If you experiment, change one thing at a time, wait at least a week to judge, and track BP/HR, sleep, mood, and focus. Your journal is your superpower.
Electrolytes and hydration
Simple wins matter
Hydration reduces headaches and jitters. Aim for steady fluids through the day. An electrolyte packet or a pinch of salt with water after workouts can help if you run warm or sweat a lot.
Food and habits
Food timing tips
With or without food?
Sunosi can be taken with or without food. Choose the routine you'll stick to. Many people do best taking it early morning, soon after waking, to protect nighttime sleep.
Coffee and energy
How much is too much?
Set a caffeine "budget." For many, that's 1 morning coffee or tea plus an optional small cup late morning. If you notice tremor, a racing pulse, or afternoon anxiety, reduce or stop caffeine and reassess in three days.
Sleep hygiene notes
Timing and light matter
Take Sunosi early. Limit caffeine after late morning. Get bright light in your eyes within an hour of waking (ideally outdoors). Keep workouts earlier if evenings make you wired. Protect an 8-hour sleep windowotherwise you'll be chasing alertness with a leaky bucket.
When to avoid
Strong cautions first
Absolute and strong avoid list
Do not combine with MAOIs within 14 days. Avoid if you have severe or uncontrolled hypertension or serious arrhythmias unless a specialist is closely involved. If you're pregnant or planning pregnancy, discuss risks vs. benefits with your clinician.
Close monitoring cases
Situations for extra care
Moderate hypertension, anxiety disorders, bipolar disorder, glaucoma, and kidney disease. Sunosi is renally cleared, so dosing by eGFR is key if kidneys are not at full strength. Your prescriber will typically use a lower dose if your eGFR is reduced and avoid use if severely impaired.
Red-flag symptoms
When to get urgent help
Call for urgent care if you have chest pain, pounding or severe headache, fainting, a racing or irregular heartbeat that doesn't settle, or severe agitation. Trust your instincts: if it feels "not right," get checked.
Use it safely
Heart and pressure
Practical monitoring plan
Before starting, get baseline BP/HR (three readings on different days). Then, for the first 2 weeks, check daily at the same time. Call your clinician if your average BP is climbing or your resting HR jumps by 1520 bpm and stays there. Keep a lognothing fancy, notes on your phone are fine.
Anxiety and sleep
Small tweaks go far
If you're sensitive to activation, start low and dose early. Layer in non-drug supports: consistent wake time, sunlight, a wind-down ritual, and limiting doom-scrolling at night. If anxiety persists, ask about lowering your dose or trying an alternative.
Kidney function
Dose by eGFR
With reduced kidney function, Sunosi can stick around longer. Your prescriber will adjust dose based on eGFR. Watch for signs of accumulation: stronger-than-usual stimulation, insomnia, higher BP/HR, or new headaches. Bring your readings to follow-up visits.
Different sleep causes
Tailor by condition
OSA? Prioritize CPAP or oral appliance therapySunosi works best when your airway is treated. Narcolepsy? Align Sunosi timing with your daily rhythm. Shift work? Consider dosing to match your wake period, but leave a healthy buffer before sleep to avoid insomnia.
Real scenarios
Sunosi plus decongestants
Cold season plan
If you reach for pseudoephedrine or phenylephrine, your BP/HR may spike. Try alternatives first: saline rinses, intranasal steroid sprays, humidifier, warm showers. If you truly need a decongestant, consider the lowest dose, shortest duration, and track vitals. Pause if headaches or palpitations appear.
Weekend social drinks
Smart spacing tips
Take Sunosi early morning. If you'll drink in the evening, keep it light and hydrate between drinks. Eat before alcohol. Check in with your body: any racing heart, flush, or unusual anxiety? That's your cue to stop. Protect sleepaim to finish drinks at least 3 hours before bed.
SSRIs and a nootropic
One change at a time
On an SSRI and thinking about adding L-tyrosine or rhodiola? Add only one, at a low dose, for at least a week before changing anything else. Track mood, focus, BP/HR, and sleep. If anxiety climbs or sleep worsens, back off and reassess. Your data beats guesswork.

What we don't know
Data gaps remain
Many supplement combinations lack robust studies. Individual responses vary, especially with anxiety, sleep, and BP. That's why shared decision-making and careful monitoring are so powerfulyou tailor, learn, and adjust.
Quick tools
Interaction pre-check
Five-question checklist
1) Does this new item raise BP/HR or act as a stimulant? 2) Does it affect sleep? 3) Is it an MAOI or interact with norepinephrine/dopamine? 4) Do I have kidney issues that could change dosing? 5) How will I monitor and for how long?
Daily tracking
Simple monitoring log
Each morning: Sunosi dose/time, BP/HR after sitting 5 minutes. Midday: caffeine count. Evening: alcohol amount/time. Night: sleep start, wake time, and quick note (jittery, focused, calm, wired). Review weekly for patterns.
Escalate care
When to call or go in
Call your clinic if average BP rises above your agreed target or HR stays 1520 bpm above baseline. Go to urgent care or ER for chest pain, severe or "worst-ever" headache, fainting, or a pounding/irregular heartbeat that won't settle.
Here's the bottom line. Sunosi can be a game-changer for daytime sleepinessbut the details matter. Interactions with alcohol, supplements, and certain medications can push up blood pressure, stir anxiety or insomnia, or mute the benefits you want. Keep it simple: know the "avoid" list (especially MAOIs), watch your BP/HR, limit add-on stimulants like caffeine and decongestants, and loop in your clinician before adding new meds or supplements. If something feels offpounding headache, chest pain, racing heartpause and get help. With a few safeguards and honest check-ins, most people land on a steady, safe routine.

FAQs
Can I take Sunosi with over-the-counter cold medicines?
Most decongestants like pseudoephedrine or phenylephrine can raise blood pressure and heart rate, which may compound Sunosi’s effects. Use them only for a short time, at the lowest dose, and monitor your vitals. Safer alternatives include saline rinses or intranasal steroid sprays.
Is it safe to drink alcohol while on Sunosi?
Occasional moderate alcohol (up to 1 drink for women, 2 for men) is generally acceptable if you space it several hours after taking Sunosi and keep an eye on blood pressure and sleep quality. Avoid alcohol if you have uncontrolled hypertension, arrhythmias, or a history of substance misuse.
Do I need to avoid caffeine when taking Sunosi?
Caffeine adds to Sunosi’s stimulant effect. Limit total caffeine to about 200–300 mg per day (roughly one strong coffee) and watch for jitteriness, rapid heart rate, or insomnia. Reduce or eliminate caffeine if you notice these symptoms.
What should I do if I’m prescribed an MAOI?
Sunosi is contraindicated with MAOIs. You must stop the MAOI at least 14 days before starting Sunosi and wait the same washout period if switching from Sunosi to an MAOI. Always confirm with your prescriber before making changes.
How can I monitor my blood pressure while on Sunosi?
Take baseline readings on three separate days before starting Sunosi. For the first two weeks, check your blood pressure and resting heart rate daily at the same time. Contact your clinician if the average BP rises above your target or if resting HR increases by 15–20 bpm and stays elevated.
