* *ADVISORY* *Safety data are lacking on the use of evening primrose oil by pregnant or nursing women. Evening primrose oil may have the potential to lower the seizure threshold in certain patients, thereby increasing the likelihood of seizure. It also has the potential for interaction with warfarin, a common blood thinner. Therefore, pregnant women and all patients on antidepressants, seizure medications, or warfarin should avoid evening primrose oil.
DOSAGE:The typical daily dosage to treat breast pain or eczema is 2-4 grams daily. For eczema, evening primrose oil capsules containing 360 milligrams of linoleic acid and 45 milligrams of GLA were taken twice daily, in a dose of 1-6 capsules, for up to 12 weeks. For breast pain, 1 gram of evening primrose oil was taken three times daily.
CONCLUSION:We conclude that evening primrose oil is a safe and effective adjunct product for treating rheumatoid arthritis, eczema, and fibrocystic breast disease. Unfortunately, the full anti-inflammatory effect may take up to 6 months to become apparent.
