HelloPharmacist Scorecard of Evening Primrose Alcohol Free by Herbal Terra

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
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: evening primrose seed extract in powdered form. Evening primrose is a plant whose oil is used as a dietary supplement.

The liquid also contains two inactive ingredients — glycerin and water — that serve as the base for the formulation.

Does it work?

Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not assessable

This is a single-ingredient Evening Primrose product and its label doesn't state a use — see Evening Primrose's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The evidence for evening primrose is mixed and often limited. For asthma, it's rated possibly ineffective.

For mastalgia (breast pain or tenderness), it's likely ineffective. For other uses on file — abortion, acne, hysteroscopy, and attention deficit-hyperactivity disorder (ADHD) — there isn't enough reliable evidence to rate whether it works.

Talk with your pharmacist or doctor about whether this product makes sense for what you're considering it for.

The evidence, ingredient by ingredient Evening Primrose

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Evening primrose is generally well tolerated in the short term, though long-term safety data are limited. The most common side effects reported with oral use are digestive: abdominal pain, bloating, diarrhea, indigestion, gas, nausea, and vomiting.

Some people have reported dizziness, headache, skin rash, or acne. There's a theoretical concern about seizure risk in people with schizophrenia taking phenothiazines, though evidence is limited.

For pregnancy and breastfeeding, the safety data suggest it's possibly safe, but evidence is unclear — talk with your doctor before using it if you're pregnant or nursing.

Side effects, ingredient by ingredient Evening Primrose

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Evening Primrose.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; lithium.
  • For scale: 233 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before taking this product, double-check with your pharmacist or doctor if you're on blood thinners or antiplatelet drugs (moderate risk of increased bleeding), lithium (moderate risk of reduced levels), phenothiazines like chlorpromazine (moderate risk of seizure-threshold lowering), or the HIV medication lopinavir/ritonavir (moderate risk of increased drug levels). Also mention any other medications your liver processes, since evening primrose may affect some of them.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Evening primrose might be worth considering if you've researched it for a specific use and your doctor is on board — but check your medications first, especially if you take blood thinners, mood stabilizers, or antipsychotics. If digestive upset is a concern for you, this product may not be the best fit.

Run your exact meds through the interaction checker before you start.

Evening Primrose Seed Extract, Powdered5 drug types · 233 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, evening primrose oil may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Evening primrose oil contains gamma linolenic acid (GLA). There is preliminary clinical evidence that GLA can reduce platelet aggregation and prolong bleeding time.

Likelihood Possible Evidence D
Lithium

Theoretically, concomitant use of lithium with evening primrose oil might decrease lithium levels and effects.
In a case report, a patient on a stable dose of lithium for 10 years experienced a reduction in lithium levels after taking evening primrose oil 500 mg daily. Baseline levels were 0.69 mmol/L, which decreased to 0.37 mmol/L after 2 months and 0.23 mmol/L after 3 months of use. Lithium levels increased within 6 weeks of discontinuing evening primrose oil, to 0.73 mmol/L; no clinical effects were noted.

Likelihood Possible Evidence D
Lopinavir/Ritonavir (Kaletra)

Theoretically, evening primrose oil might increase the levels and effects of lopinavir.
In a case report, an HIV patient who took evening primrose oil (Efamol) along with lopinavir/ritonavir experienced an increase in serum levels of lopinavir to 15.2 mg/L. Six weeks after discontinuing evening primrose oil, levels of lopinavir returned to the normal range of 5-10 mg/L. When re-challenged with evening primrose oil for a week, the patient's lopinavir levels increased from 6.69 to 8.11 mg/L. It is suspected that evening primrose oil increases levels of lopinavir by inhibiting cytochrome P450 3A4 (CYP3A4), which metabolizes lopinavir. However, this effect has not been reported in other research.

Likelihood Possible Evidence D
Phenothiazines

Theoretically, taking evening primrose oil with phenothiazines might increase the risk of convulsions.
Evening primrose oil contains gamma-linolenic acid (GLA). There is some concern that taking supplements containing GLA might cause seizures, or lower the seizure threshold, when taken with phenothiazines. In one report, three patients with schizophrenia who had received phenothiazines developed EEG changes suggestive of temporal lobe epilepsy after starting treatment with GLA, although none experienced an actual seizure. In another report, two patients with schizophrenia who were stabilized on phenothiazines developed seizures when evening primrose oil 4 grams daily was added. One of these patients had a prior history of seizures. It is unclear whether evening primrose oil had any additive epileptogenic effects with the phenothiazines; there is no evidence that taking evening primrose oil alone causes seizures.

Likelihood Possible Evidence D
Cytochrome P450 2C9 (Cyp2C9) Substrates

Theoretically, evening primrose may increase the levels and clinical effects of CYP2C9 substrates.
In vitro research shows that linoleic acid, a constituent of evening primrose oil, inhibits CYP2C9.

Evening Primrose Alcohol Free by Herbal Terra: Common Questions

Does Evening Primrose Alcohol Free by Herbal Terra interact with any medications?
Yes. Based on its ingredients, Evening Primrose Alcohol Free has a known interaction with 233 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Evening Primrose Alcohol Free contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Can I take this if I'm pregnant or breastfeeding?
The safety data suggest evening primrose is possibly safe in both pregnancy and breastfeeding, but evidence is unclear. Because of that uncertainty, it's best to talk with your doctor before using it if you're pregnant or nursing — they know your full history and can give you personalized advice.
What side effects might I notice?
Most people tolerate it well, but the most common side effects are digestive: stomach pain, bloating, diarrhea, indigestion, gas, nausea, or vomiting. Some people have reported dizziness, headache, rash, or acne. If these bother you, stop and talk with your pharmacist.
Does evening primrose actually work?
The evidence is limited and mixed. For asthma it's rated possibly ineffective, and for breast pain it's likely ineffective. For other conditions like acne and ADHD, we simply don't have enough reliable data yet to say whether it works.
Is this safe to use long-term?
It's generally well tolerated in the short term, but we don't have strong long-term safety data. If you're thinking about using it regularly, that's worth discussing with your pharmacist or doctor.
Why do I need to check my medications before starting this?
Evening primrose can interact with blood thinners, mood stabilizers, antipsychotics, and HIV medications, among others — potentially changing how they work or increasing side effects. Checking your exact meds first helps you and your pharmacist spot any conflicts.
