Evening Primrose Oil
Indications
Evening primrose oil is a dietary supplement made from the seeds of the evening primrose plant. It is traditionally used for breast pain linked to the menstrual cycle, premenstrual symptoms, dry or itchy skin and eczema, and menopausal discomfort. Scientific evidence for these uses is limited and mixed, and it should not replace treatment prescribed by a doctor.
How It Works
The oil is rich in gamma-linolenic acid (GLA), an omega-6 fatty acid. The body uses GLA to make substances involved in skin health and in controlling inflammation, which is thought to explain its traditional uses.
Dosage and Administration
Take as directed on the label or by your doctor, usually soft gel capsules taken once or twice a day with food. Benefits, if any, may take several weeks to appear. Do not take more than the recommended amount.
Interactions
It may increase the risk of bleeding when taken with blood thinners or antiplatelet medicines such as Warfarin, Clopidogrel or Aspirin. It may lower the seizure threshold, especially with phenothiazine medicines such as Chlorpromazine. Tell your doctor if you take these or any other medicines.
Contraindications
Do not use if you are allergic to evening primrose. Avoid in people with epilepsy or a bleeding disorder unless a doctor advises it, and stop at least 2 weeks before planned surgery.
Side Effects
It is usually well tolerated. Possible side effects include mild stomach upset, nausea, soft stools, bloating and headache. Allergic reactions are rare.
Get urgent medical help if you have a seizure, unusual bleeding or bruising, or signs of a serious allergic reaction such as swelling of the face or throat or difficulty breathing.
Pregnancy and Lactation
Its safety in pregnancy is not established, and it has been linked to pregnancy complications, so avoid it during pregnancy unless your doctor recommends it. Ask your doctor before use while breastfeeding.
Precautions and Warnings
Use with care if you have epilepsy, schizophrenia treated with phenothiazines, or a bleeding problem. See a doctor if breast pain persists or you notice a lump. Keep out of reach of children and do not give to children without medical advice.

Large amounts may cause stomach pain and loose stools. Stop taking it and seek medical advice if symptoms are troublesome.
