Insufficient reliable information available; avoid using.
POSSIBLY SAFE ...when used orally and appropriately for up to 12 months (1784,1788,82041,82074,82089,82091,82120,82121,82151,82152)(82153,82154,82179,82180,82182,82183,104522,106845,110744). ...when used intravenously and appropriately, short-term (82074,82099,82147,82158,82159,82186,110744).
PREGNANCY: POSSIBLY UNSAFE
when used orally.
In June 2019, the US Food and Drug Administration (FDA) issued a statement of warning that those who are pregnant or who could become pregnant should avoid vinpocetine (95751). In rats, vinpocetine has been associated with an increased risk of miscarriage at a dose of 60 mg/kg daily and with reduced fetal weight and increased incidence of birth defects at a dose of 5-20 mg/kg. Based on pharmacokinetic analyses, a daily vinpocetine dose of 10 mg in humans is comparable to a daily dose of 5 mg/kg in rats (99701).
LACTATION:
Insufficient reliable information available; avoid using.
Below is general information about the interactions of the known ingredients contained in the product AVH. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
Theoretically, acetyl-L-carnitine might increase the anticoagulant effects of acenocoumarol.
Details
L-carnitine, the parent compound of acetyl-L-carnitine, might enhance the anticoagulant effects of acenocoumarol, an oral anticoagulant that is similar to warfarin, but shorter-acting (9878,12165). There are at least two case reports of INR elevation when L-carnitine was taken with acenocoumarol. In one case, a 33-year-old male with a previously stable INR had an elevated INR of 4.65 after L-carnitine was started and continued for 10 weeks. INR normalized after discontinuation of the L-carnitine-containing product (12165). It is unclear if such an interaction would also occur with acetyl-L-carnitine.
|
Theoretically, acetyl-L-carnitine might increase the risk of serotonergic side effects, including serotonin syndrome and cerebral vasoconstrictive disorders, when taken with serotonergic drugs.
Details
Animal research shows that acetyl-L-carnitine can increase levels of serotonin in the brain (95065).
|
Theoretically, acetyl-L-carnitine might decrease the effectiveness of thyroid hormone replacement.
Details
L-carnitine appears to act as a peripheral thyroid hormone antagonist by inhibiting entry of thyroid hormone into the nucleus of cells (12761). Taking L-carnitine also seems to diminish some of the symptoms of hyperthyroidism (8047). It is unclear if such an interaction would occur with acetyl-L-carnitine.
|
Theoretically, acetyl-L-carnitine might increase the anticoagulant effects of warfarin.
Details
|
Theoretically, huperzine A might decrease the effects of anticholinergic drugs.
Details
|
Theoretically, concurrent use of huperzine A with cholinergic drugs might increase the effects and side effects of these medications.
Details
Huperzine A can inhibit acetylcholinesterase (AChE) and might cause cumulative effects if used with cholinergic drugs (3131).
|
Vinpocetine might increase the risk of bleeding when taken with anticoagulant or antiplatelet drugs.
Details
Clinical research shows that vinpocetine decreases red blood cell aggregation, as well as plasma and whole blood viscosity. This effect has been seen with intravenous vinpocetine 1 mg/kg and oral vinpocetine 30 mg daily (82101,82119). Vinpocetine also seems to have antiplatelet effects (1801,10061,82117).
|
Theoretically, vinpocetine might increase levels of drugs metabolized by CYP2C9.
Details
In vitro research shows that vinpocetine weakly inhibits CYP2C9 (92933). However, this effect has not been reported in humans.
|
Vinpocetine might modestly increase the risk of bleeding when taken with warfarin.
Details
Clinical research shows that the combination of warfarin and vinpocetine leads to slight increases in prothrombin time and the area under the concentration curve for warfarin. However, these increases were small, and researchers suggest that this interaction is not likely to be clinically significant in most patients (10829).

Below is general information about the adverse effects of the known ingredients contained in the product AVH. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
General
...Orally, acetyl-L-carnitine is generally well tolerated.
Most Common Adverse Effects:
Orally: Agitation, dry mouth, headache, insomnia, and reduced appetite. A metabolite of acetyl-L-carnitine has been reported to cause a fishy odor of the urine, breath, and sweat.
Cardiovascular ...Orally, one patient in a pharmacokinetic study reported high blood pressure 8 hoursafter taking acetyl-L-carnitine 500 mg; however, it is unclear if this was due to acetyl-L-carnitine or another factor (95061).
Dermatologic ...Orally, a combination of acetyl-L-carnitine and alpha-lipoic acid may cause rash (90441).
Gastrointestinal ...Orally, acetyl-L-carnitine may cause nausea, vomiting, diarrhea, constipation, hiccups, abdominal distension and gastrointestinal upset or pain. However, gastrointestinal symptoms do not usually occur more often in patients receiving acetyl-L-carnitine than in patients receiving placebo (1596,1599,12743,13007,58922,90755,95063,95067,111889,111894). Acetyl-L-carnitine may also cause dry mouth and anorexia (58342). When taken orally, a combination of acetyl-L-carnitine and alpha-lipoic acid may cause diarrhea, constipation, and dyspepsia (90441).
Neurologic/CNS ...Orally, acetyl-L-carnitine may cause headache and insomnia (90760,90767,95063). In one clinical trial, two patients with antiretroviral toxic neuropathy reported paresthesia, pain, and neuropathy after taking acetyl-L-carnitine 1000 mg daily (58342). A case of mania has been reported for a patient with bipolar I disorder currently in remission. The patient presented with symptoms after taking multiple supplements for the past 4 weeks including acetyl-L-carnitine 1000 mg twice daily. The symptoms appeared 3 days after beginning to take acetyl-L-carnitine and worsened over the next week. The patient had increased speech rate and volume and reported increased energy levels and racing thoughts. The patient's parent reported irritability and an increase in loud behaviors at home, similar to a previous episode of mania. The patient was advised to discontinue acetyl-L-carnitine, and the manic symptoms disappeared 3 days later (95062).
Psychiatric ...Orally, acetyl-L-carnitine may cause agitation (restlessness and motor overactivity) (1596,1599,12743,13007). Side effects reported in people with Alzheimer disease include psychiatric disturbances such as depression, mania, confusion and aggression, but it is not clear whether these are due to acetyl-L-carnitine or the condition itself (1594,1595,1596,1597,1598,1599,9105,10391).
Other ...One of the metabolites of acetyl-L-carnitine can cause the urine, breath, and sweat to have a fishy odor (12756). Also, foul smelling urine has been reported following oral use of a combination of acetyl-L-carnitine and alpha-lipoic acid (90441).
General
...Orally, huperzine A seems to be well tolerated.
There is currently a limited amount of information about the tolerability of intramuscular huperzine A.
Most Common Adverse Effects:
All ROAs: Huperzine A can cause dose-dependent cholinergic side effects such as blurred vision, constipation, diarrhea, dizziness, dry mouth, insomnia, nausea, sweating, and vomiting.
Cardiovascular ...Orally, huperzine A might cause decreased heart rate (3138,93482). There are two cases reported where consumption of a tea mistakenly brewed from Lycopodium selago, a source of huperzine A, has resulted in significant cholinergic toxicity, including hypertension (13193).
Gastrointestinal ...Orally, huperzine A can cause cholinergic side effects such as nausea, vomiting, diarrhea, and anorexia (93480,93481,93482,93483). Constipation and thirst have also been reported (93482,93483). In two case reports, consumption of a tea mistakenly brewed from Lycopodium selago, a source of huperzine A, has resulted in significant cholinergic toxicity, including vomiting and diarrhea (13193).
Musculoskeletal ...In two case reports, consumption of a tea mistakenly brewed from Lycopodium selago, a source of huperzine A, has resulted in significant cholinergic toxicity, including leg cramps (13193).
Neurologic/CNS ...Orally, huperzine A can cause cholinergic side effects such as dizziness (3140,55613,93481,93482) and sweating (93482). Huperzine A can also cause hyperactivity and insomnia (3138,3140,55613,93482). Fainting has also been reported (4624). In two case reports, consumption of a tea mistakenly brewed from Lycopodium selago, a source of huperzine A, has resulted in significant cholinergic toxicity, including sweating and slurred speech (13193).
