Zinc Sulfate Side Effects

Zinc sulfate is primarily used to treat zinc deficiencies. Zinc is a mineral required for protein synthesis. Zinc plays a major role in the maintenance of every organ and system in the body. You should treat a zinc deficiency as soon as it is diagnosed to prevent more serious complications. You should only take zinc sulfate after consulting your doctor to ensure that you do not overdose. Zinc sulfate in low doses has few side effects; however, excess zinc in the body can impede on practically every function of the body.

Digestive Trouble

An upset stomach, nausea or vomiting may occur after taking oral zinc sulfate You may experience abdominal cramps, diarrhea and headaches in response to an acute overdose of zinc sulfate, according to Office of Dietary Supplements. If you experience digestive problems immediately after zinc sulfate digestion, you are probably taking an excessively high dose or are uniquely sensitive to zinc's effects. If you experience chronic digestive problems, talk to your doctor about methods to avoid these side effects. Taking zinc sulfate with your meals may minimize digestive problems.

Kidney Problems

Chronic exposure to high levels of zinc sulfate may cause zinc to accumulate in the kidneys. Zinc accumulation may prevent the kidneys from filtering toxins efficiently from the body and increase the rate of hospitalization due to urinary tract infections, according to a report published in 2007 in the "Journal of Urology". You may minimize the possibility of this side effect by drinking sufficient fluids to flush your system. If you begin to experience any pain in your lower abdomen or genital area, talk to your doctor. Toxin accumulation can eventually damage your kidneys permanently if not taken care of promptly.

Mineral Deficiency

Every organ in your body requires zinc; however, too much zinc is not easily processed. Excess zinc may compete for absorption with other minerals and induce deficiencies of those minerals, such as iron, copper and magnesium. If you begin to experience muscle weakness or fatigue, these may be early signs of excess zinc and other mineral deficiencies, according to the Nutritional Health Supplements Guide.
