Indications
Cupric sulphate (copper sulphate) is a source of copper, a trace mineral the body needs in very small amounts. It is mainly found as an ingredient of multivitamin and mineral supplements, used to prevent or correct nutritional deficiencies, for example with a poor diet, during pregnancy or while recovering from illness. Doctors may also use it to treat a proven copper deficiency.
How It Works
Copper helps several enzymes in the body work. It is needed to use iron and make red blood cells, to keep nerves, bones and blood vessels healthy, and to support the immune system.
Dosage and Administration
Supplements usually provide about 1 to 2 mg of copper a day; take them as directed on the pack or by your doctor. Treatment of a copper deficiency is as prescribed. Adults should not take more than 10 mg of copper a day from all sources, so do not take several copper-containing products together unless advised. Taking it with or after food can reduce stomach upset.
Interactions
High doses of Zinc reduce copper absorption. Penicillamine and Trientine remove copper from the body. Iron supplements and antacids taken at the same time may reduce absorption. Copper may reduce the absorption of some antibiotics (such as Tetracycline and Ciprofloxacin), so take them at least 2 hours apart.
Contraindications
- Allergy to any ingredient of the product.
- Wilson’s disease or other conditions in which copper builds up in the body.
Side Effects
At normal supplement doses side effects are uncommon. Some people get nausea, stomach upset or a metallic taste.
Get urgent medical help if you have: repeated vomiting (especially blue-green vomit), severe stomach pain, bloody diarrhoea, yellow skin or eyes, dark urine, or swelling of the face, lips or throat or difficulty breathing.
Pregnancy and Lactation
Copper is needed during pregnancy and breastfeeding, and the small amounts in pregnancy multivitamin products are considered safe. Do not take extra copper beyond the recommended amount unless your doctor advises it.
Precautions and Warnings
Tell the doctor if you have liver disease or a problem with bile flow, as copper may build up. Do not take high doses for long periods without medical advice. Keep mineral supplements well away from children.
Overdose
Swallowing a large amount of copper sulphate is poisonous. It can cause vomiting, stomach pain, diarrhoea, and damage to the liver, kidneys and blood cells. Go to hospital at once.
Therapeutic Class
