Zinc sulfate is a supplement used to treat or prevent zinc deficiency that may occur in individuals on an inadequate diet, in malabsorption syndromes (inability of your intestines to absorb certain nutrients from the food you eat), conditions with increased tissue loss (e.g. trauma, burns), and during parenteral feeding.
This medicine is a source of zinc, which is an important trace element and involved in many body enzyme functions.
Take Zinc sulfate exactly as directed by your doctor or according to the instructions on the label. Do not take more or less than instructed by your doctor.
Ask your doctor or pharmacist whether you should take this medicine with or without food. Different brands of this medicine may be taken differently. Try to take it at the same time each day.
Zinc sulfate is available as a capsule, effervescent tablet, and oral syrup.
If you are taking the capsule, swallow it whole with a glass of water.
If you are taking the effervescent tablet, dissolve the tablet in a glass of water and drink the solution.
If you are giving the oral syrup to a child, shake the bottle well before giving the medicine to ensure that the liquid is evenly mixed. Use the measuring spoon or cup provided to measure the prescribed dose.
Zinc sulfate must be taken regularly for it to be effective. Continue taking this medicine even when you feel better. Do not stop taking it unless instructed by the doctor.
Take the missed dose as soon as you remember. If it is almost time for your next dose, skip the missed dose and return to your normal dosing schedule.
DO NOT double a dose under any circumstances.
If you often forget to take your medicine, let your doctor and pharmacist know.
