HelloPharmacist Scorecard of Ashwagandha by R-U-Ved
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
Full disclosure
This product contains 2 active ingredients: ashwagandha and withanoloides. Ashwagandha is an adaptogenic herb traditionally used to help manage stress and promote calm.
Withanoloides is one of the active compounds in ashwagandha thought to be responsible for many of its effects. The capsule itself is made from vegetarian material.
Does it work?
Moderate evidence
Ashwagandha is possibly effective for insomnia, anxiety, stress, and generalized anxiety disorder (GAD) according to the evidence we hold. For bipolar disorder, the evidence isn't established enough to rate it.
If you're considering this for one of those first four uses, talk with your pharmacist or doctor about whether it might fit your situation and how it compares to other options.
How safe is it?
Well-documented data
Ashwagandha is generally well tolerated short-term in healthy adults, though long-term safety data are limited. The most common side effects when taken by mouth are diarrhea, upset stomach, nausea, and vomiting — though these don't usually happen at typical doses.
Drowsiness has also been reported. Rare but serious side effects include liver injury and cases of hepatitis and liver failure linked to ashwagandha use.
There's also an isolated case report of reversible cerebral vasoconstriction (a narrowing of brain blood vessels) in someone taking ashwagandha with other drugs. Ashwagandha is not recommended during pregnancy — the traditional use raises concerns about miscarriage — and there isn't enough safety data to breastfeed while taking it.
Talk with your doctor or pharmacist if you're pregnant, planning pregnancy, or breastfeeding.
Meds to double-check
Moderate interaction found
Before taking this product, check with your pharmacist if you're on CNS depressants, benzodiazepines, blood pressure medications, diabetes drugs, thyroid hormone, immunosuppressants, or any drugs that can damage your liver. Ashwagandha may boost the effects of sedatives and lower blood pressure and blood sugar, and it can interfere with how immunosuppressants and some other drugs work.
The bottom line
Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
Ashwagandha is possibly effective for insomnia, anxiety, stress, and GAD in the short term. If you take sedatives, blood pressure medications, diabetes drugs, thyroid hormone, or immunosuppressants, you need to check your exact medications before starting this.
Also avoid it if you're pregnant or breastfeeding. Run your medication list through our interaction checker, and talk with your pharmacist.

Ashwagandha by R-U-Ved Drug Interactions
HelloPharmacist Interaction Report
Ashwagandha by R-U-Ved has documented interactions with multiple medication types.
The most serious concern is with CNS depressants (drugs that slow your brain and nervous system) — ashwagandha may boost their sedative effects, which includes benzodiazepines like Valium and Klonopin, as well as barbiturates and other sedatives.
Read the full breakdown — every affected drug type, severity by severity
You'll also want to check if you take blood pressure medications (antihypertensives), diabetes drugs, or thyroid hormone. Ashwagandha may lower blood pressure and blood sugar, raising the risk of dizziness or low blood sugar.
With thyroid hormone, it could increase both the therapeutic and side effects. It may also reduce how well immunosuppressant drugs work after transplant or for certain autoimmune conditions.
One more: ashwagandha can interact with drugs that damage the liver (hepatotoxic drugs), and there are rare case reports linking it to serious liver injury. It may also affect how your liver processes certain medications (CYP1A2 substrates), though this is a Minor interaction.
We could not check withanoloides — we hold no data for that ingredient. Use the search tool below to run your exact medications against this product before you start.

For each ingredient in Ashwagandha with known interactions, here are the types of medications it can affect. Open any type for the detail — or search your exact drug in the checker above.
Ashwagandha
Antidiabetes Drugs
Theoretically, taking ashwagandha with antidiabetes drugs might increase the risk of hypoglycemia.
There is preliminary clinical evidence suggesting that ashwagandha might lower blood glucose levels. Theoretically, ashwagandha might have additive effects when used with antidiabetes drugs and increase the risk of hypoglycemia.
Antihypertensive Drugs
Theoretically, taking ashwagandha with antihypertensive drugs might increase the risk of hypotension.
Animal research suggests that ashwagandha might lower systolic and diastolic blood pressure. Theoretically, ashwagandha might have additive effects when used with antihypertensive drugs and increase the risk of hypotension.
Benzodiazepines
Theoretically, taking ashwagandha might increase the sedative effects of benzodiazepines.
There is preliminary evidence that ashwagandha might have an additive effect with diazepam (Valium) and clonazepam (Klonopin). This may also occur with other benzodiazepines.
Cns Depressants
Theoretically, taking ashwagandha might increase the sedative effects of CNS depressants.
Ashwagandha seems to have sedative effects. Theoretically, this may potentiate the effects of barbiturates, other sedatives, and anxiolytics.
Hepatotoxic Drugs
Theoretically, taking ashwagandha with hepatotoxic drugs might increase the risk of liver damage.
Ashwagandha has been linked to cases of acute hepatitis, liver failure, hepatic encephalopathy, autoimmune hepatitis, the need for liver transplantation, and death due to liver failure.
Immunosuppressants
Theoretically, taking ashwagandha might decrease the effects of immunosuppressants.
Ashwagandha has demonstrated immunostimulant effects in humans. Animal research has shown that ashwagandha can attenuate the immunosuppression caused by cyclophosphamide.
Thyroid Hormone
Ashwagandha might increase the effects and adverse effects of thyroid hormone.
Concomitant use of ashwagandha with thyroid hormones may cause additive therapeutic and adverse effects. Preliminary clinical research and animal studies suggest that ashwagandha boosts thyroid hormone synthesis and secretion. In one clinical study, ashwagandha increased triiodothyronine (T3) and thyroxine (T4) levels by 41.5% and 19.6%, respectively, and reduced serum TSH levels by 17.4% from baseline in adults with subclinical hypothyroidism.
Cytochrome P450 1A2 (Cyp1A2) Substrates
Theoretically, ashwagandha might decrease the levels and clinical effects of CYP1A2 substrates.
In vitro research shows that ashwagandha extract induces CYP1A2 enzymes.
Cytochrome P450 3A4 (Cyp3A4) Substrates
Theoretically, ashwagandha might decrease the levels and clinical effects of CYP3A4 substrates.
In vitro research shows that ashwagandha extract induces CYP3A4 enzymes.
Serotonergic Drugs
Some animal studies have reported that ashwagandha can enhance serotonergic transmission by altering certain serotonin (5-HT) receptors. However, there is no evidence to suggest that ashwagandha increases the risk of serotonin-related effects, and there have been no published case reports of serotonin syndrome when combined with other serotonergic drugs. Nevertheless, due to the lack of extensive studies on the matter and the fact that ashwagandha appears to affect serotonergic pathways, it would be prudent to exercise caution when combining it with drugs that affect serotonin.
