HelloPharmacist Scorecard of Lipo 6X by Nutrex Research
Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.
What’s inside
Low disclosure
Lipo 6X contains 10 active ingredients designed to support weight loss and thermogenesis (heat production). The main players are caffeine anhydrous for mental alertness and energy, yohimbe (from yohimbe bark) and synephrine (from bitter orange) as stimulants, plus hordenine, tyramine, and B-phenylethylamine—all stimulant-type compounds.
It also contains glycerin (which may help with hydration and athletic performance), guggulsterones (resin extract), and proprietary blends labeled "Rapid Release Liquid Delivery" and "Thermogenesis Activating Complex" whose exact dosing is not disclosed. The capsules also hold a few inactive ingredients: polysorbate 80 (an emulsifier), vegetable cellulose (the capsule itself), and FD&C Blue #2 (food coloring).
Does it work?
Strong evidence
Evidence for Lipo 6X's ingredients is thin. Caffeine is likely effective for mental alertness and athletic performance, and glycerin is possibly effective for athletic performance.
Yohimbe, synephrine, hordenine, tyramine, and B-phenylethylamine all carry ratings of insufficient reliable evidence for weight loss, obesity, athletic performance, or any other health claim the product might suggest. The product label may claim these ingredients promote fat loss, but the science we hold doesn't back those claims.
How safe is it?
Well-documented data
Caffeine is generally well tolerated in moderate amounts but high doses can cause serious side effects; common ones include anxiety, insomnia, jitteriness, headache, nausea, and diarrhea. Pregnancy safety is uncertain (possibly safe to possibly unsafe), and small amounts pass into breast milk.
Glycerin is generally well tolerated orally in normal amounts but can cause bloating, nausea, diarrhea, headache, and dizziness; large medicinal doses need doctor approval. Yohimbe and synephrine are the bigger safety concerns.
Yohimbe can cause serious heart and blood pressure effects and supplement potency is unpredictable; common effects include anxiety, agitation, tremors, hypertension, tachycardia, and nausea. It's unsafe in pregnancy and should be avoided while breastfeeding.
Synephrine (bitter orange) can raise blood pressure and heart rate, especially with caffeine; serious but rare effects include heart attack, QT prolongation, seizure, and stroke. Hordenine, tyramine, and B-phenylethylamine have very limited or no human safety data but may cause stimulant effects like rapid heartbeat and high blood pressure.
Tyramine is unsafe in supplement form due to lack of safety study, and B-phenylethylamine should be avoided in pregnancy and breastfeeding. N-methyl-beta-phenylethylamine, guggulsterones, and the proprietary blends have no safety data on file.
Meds to double-check
Major interaction found
Before taking Lipo 6X, double-check with your doctor or pharmacist if you take any of these medication types: monoamine oxidase inhibitors (MAOIs) like phenelzine—risk of dangerous blood pressure spike; blood pressure medications (antihypertensives)—this product may fight their effects; antidepressants, especially older tricyclics and any that boost serotonin—risk of serious interactions; antipsychotics like clozapine; anti-seizure drugs (phenobarbital, carbamazepine); heart medications including QT-prolonging drugs and dipyridamole; diabetes medications; quinolone antibiotics; cimetidine (heartburn); barbiturates like pentobarbital; dextromethorphan (cough suppressant); or any other stimulant. If you drink alcohol regularly, talk to your doctor too—tyramine's effects may be worsened.
The bottom line
Scorecard at a glanceFormula with limited ingredient disclosure with clinical evidence supporting its stated purpose. Major medication interactions have been identified, and safety information is well characterized.
Lipo 6X is a multi-ingredient stimulant product built around caffeine, yohimbe, and synephrine. If you take any blood pressure medication, antidepressant (especially MAOIs and tricyclics), anti-seizure drug, antipsychotic, or heart medication, you need to talk this over with your doctor or pharmacist before taking it—the interaction list is long and some are serious.
Even if you're not on medications, the combination of stimulants may cause rapid heartbeat, anxiety, or high blood pressure in some people, especially those with heart or blood pressure issues. Pregnancy and breastfeeding are not recommended due to insufficient safety data and stimulant effects.

HelloPharmacist Interaction Report
Lipo 6X by Nutrex Research contains several ingredients with documented interactions: caffeine anhydrous, yohimbe, synephrine, hordenine, tyramine, and B-phenylethylamine.
The most serious interaction is between yohimbe or synephrine and monoamine oxidase inhibitors (MAOIs)—older antidepressants and Parkinson's drugs—which can cause a dangerous spike in blood pressure (hypertensive crisis).
Read the full breakdown — every affected drug type, severity by severity
Caffeine interacts with ephedrine (a Major interaction risking serious stimulant effects including heart attack), plus a lengthy list of Moderate interactions: barbiturates like pentobarbital and phenobarbital, dipyridamole (a cardiac stress-test drug), the antipsychotic clozapine, the heartburn drug cimetidine, quinolone antibiotics, and the seizure medication carbamazepine. Yohimbe has additional Moderate interactions with blood pressure medications, certain antidepressants (tricyclics), other stimulants, and drugs metabolized by liver enzymes (CYP2D6 and CYP3A4 substrates).
Synephrine adds Moderate interactions with QT-prolonging cardiac drugs, diabetes medications, dextromethorphan (cough suppressant), and reinforces the stimulant-plus-caffeine concern.
Hordenine and tyramine round out the stimulant-class risks through Moderate interactions with MAOIs and other stimulants, and tyramine specifically raises Major concerns with blood pressure drugs and alcohol. B-phenylethylamine carries Moderate interactions with serotonergic antidepressants and MAOIs.

Yohimbe
Monoamine Oxidase Inhibitors (Maois)
Concomitant use of MAOIs with yohimbe can result in additive effects.
Yohimbine, a constituent of yohimbe, has MAO inhibitory effects. At high doses, yohimbine is a non-selective inhibitor of MAO.
Antihypertensive Drugs
Theoretically, yohimbe might reduce the effects of antihypertensive drugs.
Yohimbine, a constituent of yohimbe, is an alpha-2 adrenoceptor antagonist and has been reported to increase blood pressure in clinical research. Theoretically, concomitant use of yohimbe and antihypertensive drugs can interfere with blood pressure control.
Clonidine (Catapres)
Theoretically, yohimbe might precipitate clonidine withdrawal.
Chronic clonidine use can downregulate alpha-2 adrenoreceptors. Animal research and one human case report suggest that concomitant administration of yohimbine, an alpha-2 adrenoceptor antagonist, may precipitate clonidine withdrawal and lead to sympathomimetic toxicity, including hypertensive crisis.
Cytochrome P450 2D6 (Cyp2D6) Inhibitors
CYP2D6 inhibitors may increase the levels and adverse effects of yohimbine, a constituent of yohimbe.
In vitro and clinical research shows that the yohimbe bark constituent, yohimbine, is metabolized by CYP2D6 isoenzymes. Paroxetine, a cytochrome P450 (CYP) 2D6 inhibitor, increases the maximum serum concentration of yohimbine and reduces the clearance of yohimbine compared to yohimbine alone in patients who are extensive CYP2D6 metabolizers..
Cytochrome P450 2D6 (Cyp2D6) Substrates
Theoretically, yohimbe might increase the levels and adverse effects of CYP2D6 substrates.
In vitro research suggests that yohimbine, a constituent of yohimbe bark, inhibits CYP2D6 enzyme activity.
Cytochrome P450 3A4 (Cyp3A4) Inhibitors
Theoretically, CYP3A4 inhibitors might increase the levels and adverse effects of yohimbine, a constituent of yohimbe bark.
In vitro and clinical research shows that the yohimbe bark constituent, yohimbine, is metabolized by CYP3A4 enzymes. Theoretically, drugs that inhibit CYP3A4 might increase the levels and adverse effects of yohimbine.
Paroxetine (Paxil)
Paroxetine decreases the clearance of yohimbine and may increase its effects.
Paroxetine, a cytochrome P450 (CYP) 2D6 inhibitor, increases the maximum serum concentration of yohimbine by about 350% and reduces the clearance of yohimbine by about 80% compared to yohimbine alone in patients who are extensive CYP2D6 metabolizers. No significant changes in pharmacokinetic parameters of yohimbine were observed with coadministration of paroxetine in patients who are poor CYP2D6 metabolizers.
Phenothiazines
Theoretically, using yohimbine with phenothiazines might have additive effects.
Yohimbine, a constituent of yohimbe, has alpha-2 adrenergic antagonist effects. Theoretically, combining it with phenothiazines can cause additive alpha-2 adrenergic antagonism.
Stimulant Drugs
Theoretically, taking yohimbe with stimulant drugs can have additive effects.
Yohimbine, a constituent of yohimbe, has sympathomimetic effects and increases blood pressure in a dose-dependent manner. Theoretically, taking yohimbe with stimulant drugs can have additive stimulant and hypertensive effects.
Tricyclic Antidepressants (Tcas)
Theoretically, taking yohimbe with TCAs can increase adverse effects.
A small clinical study in patients taking TCAs for at least 4 weeks shows that receiving doses of intravenous yohimbine 2.5-20 mg daily for up to 7 days precipitates severe anxiety, agitation, and tremor. The effects of yohimbe bark itself are unclear; oral yohimbe bark contains 0.6% to 1.38% yohimbine, but it is unclear how much is absorbed.
Anticoagulant/Antiplatelet Drugs
Theoretically, combining yohimbe bark with antiplatelet or anticoagulant drugs might have additive effects; however, this has not been reported in clinical research.
Research in healthy adults shows that taking yohimbine, a constituent of yohimbe bark, in doses of 8 mg or more, seems to inhibit platelet aggregation in vitro by binding to the alpha-2 adrenoceptor. The effects of yohimbe bark itself are unclear; yohimbe bark contains 0.6% to 1.38% yohimbine, but it is unclear how much is absorbed.
Cytochrome P450 1A2 (Cyp1A2) Substrates
Theoretically, yohimbe might decrease the levels and clinical effects of CYP1A2 substrates.
In vitro research shows that yohimbe extract induces CYP1A2 enzymes.
Cytochrome P450 3A4 (Cyp3A4) Substrates
Theoretically, yohimbe might decrease the levels and clinical effects of CYP3A4 substrates.
In vitro research shows that yohimbe extract induces CYP3A4 enzymes.
Synephrine
Midazolam (Versed)
Bitter orange might increase blood levels of midazolam.
One small clinical study shows that bitter orange juice can increase midazolam levels, likely through inhibition of cytochrome P450 3A4 (CYP3A4). Theoretically, bitter orange might increase the risk of midazolam-related adverse effects.
Monoamine Oxidase Inhibitors (Maois)
Theoretically, taking MAOIs with synephrine-containing bitter orange preparations might increase the hypertensive effects of synephrine, potentially leading to hypertensive crisis.
Bitter orange contains tyramine, octopamine, and synephrine, which are MAO substrates.
Antidiabetes Drugs
Theoretically, bitter orange might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Some clinical research shows that drinking a tea containing bitter orange and Indian snakeroot reduces fasting and postprandial glucose levels in patients with type 2 diabetes who are using antidiabetes drugs. However, it is unclear if these effects are due to bitter orange, Indian snakeroot, or the combination. An animal study also shows that p-synephrine in combination with gliclazide , a sulfonylurea, causes an additional 20% to 44% decrease in glucose levels when compared with gliclazide alone.
Caffeine
Bitter orange might increase blood pressure and heart rate when taken with caffeine.
Small clinical studies show that taking bitter orange in combination with caffeine can increase blood pressure and heart rate in otherwise healthy normotensive adults. Theoretically, this might increase the risk of serious cardiovascular adverse effects.
Colchicine
Bitter orange might affect colchicine levels.
Colchicine is a substrate of P-glycoprotein and cytochrome P450 3A4 (CYP3A4). Bitter orange has been reported to inhibit CYP3A4 and increase levels of CYP3A4 substrates. However, one small clinical study in healthy adults shows that drinking bitter orange juice 240 mL twice daily for 4 days and taking a single dose of colchicine 0.6 mg on the 4th day decreases colchicine peak serum levels by 24%, time to peak serum level by 1 hour, and overall exposure to colchicine by 20%. The clinical significance of this finding is unclear.
Cytochrome P450 3A4 (Cyp3A4) Substrates
Bitter orange might increase levels of drugs metabolized by CYP3A4.
Small clinical studies suggest that single or multiple doses of freshly squeezed bitter orange juice 200-240 mL can inhibit CYP3A4 metabolism of drugs, causing increased drug levels and potentially increasing the risk of adverse effects. However, the extent of the effect of bitter orange on CYP3A4-mediated drug interactions is unknown. Some evidence suggests that bitter orange selectively inhibits intestinal CYP3A4, but not hepatic CYP3A4. Its effect on P-glycoprotein, which strongly overlaps with CYP3A4 interactions, is unclear. One small clinical study shows that drinking 8 ounces of freshly squeezed bitter orange juice has no effect on cyclosporine, which seems to be more dependent on hepatic CYP3A4 and P-glycoprotein than intestinal CYP3A4.
Dextromethorphan (Robitussin Dm, Others)
Bitter orange might increase blood levels of dextromethorphan.
One small clinical study shows that bitter orange juice increases dextromethorphan levels, likely through cytochrome P450 3A4 (CYP3A4) inhibition. Theoretically, bitter orange might increase the risk for dextromethorphan-related adverse effects.
Felodipine (Plendil)
Bitter orange might increase blood levels of felodipine.
One small clinical study shows that bitter orange juice increases felodipine levels, likely through cytochrome P450 3A4 (CYP3A4) inhibition. Theoretically, bitter orange might increase the risk for felodipine-related adverse effects.
Indinavir (Crixivan)
Bitter orange might increase blood levels of indinavir.
One small clinical study shows that bitter orange juice slightly increases indinavir levels, but this effect is likely to be clinically insignificant. Bitter orange selectively inhibits intestinal cytochrome P450 3A4 (CYP3A4); however, the metabolism of indinavir seems to be more dependent on hepatic CYP3A4. The effect of bitter orange on other protease inhibitors has not been studied.
Qt Interval-Prolonging Drugs
Theoretically, bitter orange might have an additive effect when combined with drugs that prolong the QT interval, potentially increasing the risk of ventricular arrhythmias.
One case report suggests that taking bitter orange in combination with other stimulants such as caffeine might prolong the QT interval in some patients.
Sildenafil (Viagra)
Bitter orange juice might increase blood levels of sildenafil.
A small clinical study in healthy adult males shows that drinking freshly squeezed bitter orange juice 250 mL daily for 3 days and taking a single dose of sildenafil 50 mg on the 3rd day increases the peak plasma concentration of sildenafil by 18% and the overall exposure to sildenafil by 44%. Theoretically, this may be due to inhibition of cytochrome P450 3A4 by bitter orange.
Stimulant Drugs
Theoretically, bitter orange might increase the risk of hypertension and adverse cardiovascular effects when taken with stimulant drugs.
Bitter orange appears to have stimulant effects.
Cytochrome P450 2D6 (Cyp2D6) Substrates
Theoretically, bitter orange might increase levels of drug metabolized by CYP2D6.
In vitro research shows that octopamine, a constituent of bitter orange, weakly inhibits CYP2D6 enzymes. This effect has not been reported in humans.
Caffeine Anhydrous
Ephedrine
Theoretically, concomitant use might increase the risk for stimulant adverse effects.
Use of ephedrine with caffeine can increase the risk of stimulatory adverse effects. There is evidence that using ephedrine with caffeine might increase the risk of serious life-threatening or debilitating adverse effects such as hypertension, myocardial infarction, stroke, seizures, and death.
Adenosine (Adenocard)
Theoretically, caffeine might decrease the vasodilatory effects of adenosine and interfere with its use prior to stress testing.
Some evidence shows that caffeine is a competitive inhibitor of adenosine and can reduce the vasodilatory effects of adenosine in humans. However, other research shows that caffeine does not seem to affect supplemental adenosine because high interstitial levels of adenosine overcome the antagonistic effects of caffeine. It is recommended that methylxanthines and methylxanthine-containing products be stopped 24 hours prior to pharmacological stress tests. However, methylxanthines appear more likely to interfere with dipyridamole (Persantine) than adenosine-induced stress testing.
Anticoagulant/Antiplatelet Drugs
Theoretically, caffeine may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Caffeine is reported to have antiplatelet activity. Theoretically, it might increase the risk of bleeding when used concomitantly with these agents; however, this interaction has not been reported in humans.
Beta-Adrenergic Agonists
Theoretically, large amounts of caffeine might increase the cardiac inotropic effects of beta-agonists.
Carbamazepine (Tegretol)
Theoretically, caffeine might reduce the effects of carbamazepine and increase the risk for convulsions.
Animal research suggests that taking caffeine can lower the anticonvulsant effects of carbamazepine and can induce seizures when taken in doses above 400 mg/kg. Human research has shown that taking caffeine 300 mg in three divided doses along with carbamazepine 200 mg reduces the bioavailability of carbamazepine by 32% and prolongs the plasma half-life of carbamazepine 2-fold in healthy individuals.
Cimetidine (Tagamet)
Theoretically, cimetidine might increase the levels and adverse effects of caffeine.
Cimetidine decreases the rate of caffeine clearance by 31% to 42%.
Clozapine (Clozaril)
Caffeine might increase the levels and adverse effects of clozapine and acutely exacerbate psychotic symptoms.
Caffeine might increase the effects and toxicity of clozapine. Caffeine doses of 400-1000 mg per day inhibit clozapine metabolism. Clozapine is metabolized by cytochrome P450 1A2 (CYP1A2). Although researchers speculate that caffeine might inhibit CYP1A2, there is no reliable evidence that caffeine affects CYP1A2. There is also speculation that genetic factors might make some patients more sensitive to an interaction between clozapine and caffeine. In one case report, severe, life-threatening clozapine toxicity and multiorgan system failure occurred in a patient with schizophrenia stabilized on clozapine who consumed caffeine 600 mg daily.
Dipyridamole (Persantine)
Theoretically, caffeine might decrease the vasodilatory effects of dipyridamole and interfere with its use prior to stress testing.
Caffeine inhibits dipyridamole-induced vasodilation. It is recommended that methylxanthines and methylxanthine-containing products be stopped 24 hours prior to pharmacological stress tests. Methylxanthines appear more likely to interfere with dipyridamole (Persantine) than adenosine-induced stress testing.
Disulfiram (Antabuse)
Theoretically, disulfiram use might increase the levels and adverse effects of caffeine.
Disulfiram decreases the rate of caffeine clearance.
Diuretic Drugs
Theoretically, using caffeine with diuretic drugs might increase the risk of hypokalemia.
Caffeine, especially in excessive amounts, can reduce potassium levels due to stimulation of the sodium-potassium pump. Diuretics can also cause lower potassium levels.
Estrogens
Theoretically, estrogens might increase the levels and adverse effects of caffeine.
Estrogen inhibits caffeine metabolism.
Ethosuximide (Zarontin)
Theoretically, caffeine might reduce the effects of ethosuximide and increase the risk for convulsions.
Animal research suggests that caffeine 92.4 mg/kg can decrease the anticonvulsant activity of ethosuximide. However, this effect has not been reported in humans.
Felbamate (Felbatol)
Theoretically, caffeine might reduce the effects of felbamate and increase the risk for convulsions.
Animal research suggests that a high dose of caffeine 161.7 mg/kg can decreases the anticonvulsant activity of felbamate. However, this effect has not been reported in humans.
Flutamide (Eulexin)
Theoretically, caffeine might increase the levels and adverse effects of flutamide.
In vitro evidence suggests that caffeine can inhibit the metabolism of flutamide. However, this effect has not been reported in humans.
Fluvoxamine (Luvox)
Theoretically, fluvoxamine might increase the levels and adverse effects of caffeine.
Fluvoxamine reduces caffeine metabolism.
Lithium
Abrupt caffeine withdrawal might increase the levels and adverse effects of lithium.
Caffeine has diuretic activity. When abruptly discontinued, caffeine may alter the clearance of lithium. There are two case reports of lithium tremor that worsened upon abrupt coffee withdrawal and 6 case reports of elevated serum lithium levels after reducing or eliminating caffeine intake. In one case, a male with schizoaffective disorder stabilized on lithium had an elevated lithium level after reducing his caffeine intake by 87%. At a later date, he increased his caffeine intake by 6-fold, resulting in a subtherapeutic lithium level and a recurrence of psychiatric symptoms.
Monoamine Oxidase Inhibitors (Maois)
Theoretically, concomitant use might increase the risk of a hypertensive crisis.
Caffeine has been shown to inhibit monoamine oxidase (MAO) A and B in laboratory studies. Concomitant intake of large amounts of caffeine with MAOIs might precipitate a hypertensive crisis. In a case report, a patient that consumed 10-12 cups of caffeinated coffee and took the MAOI tranylcypromine presented with severe hypertension. Hypertension was resolved after the patient switched to drinking decaffeinated coffee.
Nicotine
Theoretically, concomitant use might increase the risk of hypertension.
Concomitant use of caffeine and nicotine has been shown to have additive cardiovascular effects, including increased heart rate and blood pressure. Blood pressure was increased by 10.8/12.4 mmHg when the agents were used concomitantly.
Pentobarbital (Nembutal)
Theoretically, caffeine might decrease the effects of pentobarbital.
Caffeine might negate the hypnotic effects of pentobarbital.
Phenobarbital (Luminal)
Theoretically, caffeine might reduce the effects of phenobarbital and increase the risk for convulsions.
Animal research suggests that caffeine can decrease the anticonvulsant activity of phenobarbital. However, the exact mechanism of this interaction is unclear.
Phenylpropanolamine
Theoretically, phenylpropanolamine might increase the risk of hypertension, as well as the levels and adverse effects of caffeine.
Concomitant use of phenylpropanolamine and caffeine might cause an additive increase in blood pressure. Phenylpropanolamine also seems to increase caffeine serum levels.
Phenytoin (Dilantin)
Theoretically, caffeine might reduce the effects of phenytoin and increase the risk for convulsions.
Animal research suggests that caffeine can decrease the anticonvulsant activity of phenytoin. The effect does not seem to be related to the seizure threshold-lowering effects of caffeine. However, the exact mechanism of this interaction is unclear.
Pioglitazone (Actos)
Theoretically, caffeine might increase the levels and clinical effects of pioglitazone.
Animal research suggests that caffeine can modestly increase the maximum concentration, area under the curve, and half-life of pioglitazone, and also reduce its clearance. This increased the antidiabetic effects of pioglitazone. However, the exact mechanism of this interaction is unclear.
Quinolone Antibiotics
Theoretically, quinolone antibiotics might increase the levels and adverse effects of caffeine.
Quinolones (also called fluoroquinolones) can decrease caffeine clearance by inhibiting cytochrome P450 1A2 (CYP1A2) enzyme.
Riluzole (Rilutek)
Theoretically, concomitant use might increase the levels and adverse effects of both caffeine and riluzole.
Caffeine and riluzole are both metabolized by cytochrome P450 1A2 (CYP1A2), and concomitant use might reduce the metabolism of one or both agents.
Tyramine
Antihypertensive Drugs
Tyramine may increase the risk of hypertension and reduce the effects of antihypertensive drugs.
In humans, oral and intravenous tyramine increases systolic blood pressure.
Monoamine Oxidase Inhibitors (Maois)
Concomitant use of tyramine with MAOIs may increase the risk of serious adverse effects from tyramine.
Tyramine is metabolized by monoamine oxidase. Concurrent use of MAOIs with tyramine can lead to elevated levels of tyramine in the body. This can increase the effects of tyramine, which has been reported to cause hypertension, headache, and hypertensive crisis in numerous cases. Sensitivity to tyramine can increase up to 10-fold to 100-fold in people using an MAOI. The European Food Safety Authority states that meals containing more than 50 mg of tyramine might present a risk to patients that are using third generation MAOI medications. Meals containing more than 6 mg of tyramine are likely to present a risk to patients who are taking classic MAOI medications.
Alcohol
Theoretically, concomitant use of alcohol and tyramine might increase the risk of adverse effects from tyramine.
In vitro research suggests that alcohol may potentiate the toxic effects of biogenic amines, including tyramine, possibly by decreasing their breakdown.
Stimulant Drugs
Theoretically, taking tyramine with stimulant drugs might increase the risk of adverse cardiovascular effects.
Tyramine is thought to have stimulant effects.
Hordenine
Monoamine Oxidase Inhibitors (Maois)
Hordenine is structurally similar to tyramine In vitro research shows that hordenine is a selective substrate for monoamine oxidase-B in the liver. Theoretically, concomitant use of hordenine with MAOIs might increase blood pressure, potentially leading to a hypertensive crisis.
Some MAOIs include isocarboxazid (Marplan), phenelzine (Nardil), selegiline (Eldepryl, Emsam, Zelapar), and tranylcypromine (Parnate).
Stimulant Drugs
Hordenine is structurally similar to N-methyltyramine and synephrine, constituents in bitter orange known to have stimulant properties. Theoretically, taking hordenine with drugs with stimulant properties might increase the risk of hypertension and other adverse cardiovascular effects.
Some of these drugs include amphetamine, caffeine, methylphenidate, pseudoephedrine, and many others.
Cytochrome P450 2D6 (Cyp2D6) Substrates
Hordenine weakly inhibits cytochrome P450 2D6 (CYP2D6) enzymes in vitro. Theoretically, hordenine might increase the levels of CYP2D6 substrates.
Some of drugs that are CYP2D6 substrates include amitriptyline (Elavil), clozapine (Clozaril), codeine, desipramine (Norpramin), donepezil (Aricept), fentanyl (Duragesic), flecainide (Tambocor), fluoxetine (Prozac), meperidine (Demerol), methadone (Dolophine), metoprolol (Lopressor, Toprol XL), olanzapine (Zyprexa), ondansetron (Zofran), tramadol (Ultram), trazodone (Desyrel), and others.
B-Phenylethylamine
Monoamine Oxidase Inhibitors (Maois)
Theoretically, taking phenethylamine concomitantly with MAOIs may increase adverse effects.
In humans, phenethylamine is oxidized by MAO-B to form the inactive metabolite phenylacetic acid. Animal research shows that administering an MAOI prior to phenethylamine increases the amphetamine-like effects of phenethylamine. However, low-quality clinical research has used phenethylamine with selegiline, an MAOI, with apparent safety.
Serotonergic Drugs
Theoretically, combining serotonergic drugs with phenethylamine might increase the risk of serotonergic adverse effects.
Animal research shows that phenethylamine increases levels of serotonin, norepinephrine, and dopamine. Theoretically, combining serotonergic drugs with phenethylamine might increase the risk of additive serotonergic adverse effects, including serotonin syndrome and cerebral vasoconstrictive disorders. However, low-quality clinical research has used phenethylamine with selegiline, a monoamine oxidase inhibitor (MAOI), with apparent safety.
