Part 5 in my series of posts about products which can contribute to nutrient deficiencies –
A common medication used in the treatment of rheumatoid arthritis is d-penicillamine, or Cuprimine. This medication sometimes reduces food intake by producing nausea, mouth sores, stomach pain, and tongue inflammation, and it also reduces the absorption of several nutrients, including zinc, iron, and other minerals. The drug-nutrient interactions are minimized if this medication is taken on an empty stomach one to two hours following a meal. Vitamin B6 requirements also might increase if you take this medication. Any vitamin or mineral supplements should always be taken at least two or more hours before or after the medication and should always be monitored by a physician.
