Zinc is a mineral. It is involved in a number of body enzyme functions. It is important for wound healing and for the senses of taste and smell. However, if it is taken in large quantities, it can lead to toxicity. Because of this, zinc supplements should only be taken by people with conditions that cause a loss of zinc from the body, or where there is good evidence that zinc deficiency exists. Such conditions include large skin burns, following an injury, and in some metabolic diseases where there is interference in the way zinc is absorbed from food.

Another form of zinc, called zinc acetate dihydrate (brand name Wilzin®), is used in a completely different condition known as Wilson's disease. This is a genetic disorder where there is a build-up of copper which causes serious symptoms because the body is not able to get rid of it. Treatment with zinc helps to remove the excess copper and/or prevent a further build-up. This is a specialist treatment and no further information about this brand of zinc is included below. If you have been prescribed Wilzin® capsules, please ask your doctor if you require information about your treatment.

To make sure that this is the right treatment for you, before you start taking zinc sulfate it is important that your doctor or pharmacist knows:

  • If you are pregnant or breast-feeding.
  • If you have any problems with the way your kidneys work.
  • If you are taking or using any other medicines. This includes any medicines you are taking which are available to buy without a prescription, such as herbal and complementary medicines.
  • If you have ever had an allergic reaction to a medicine.
  • Before you start this treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about zinc sulfate and will provide you with a full list of the side-effects which you could experience from taking it.
  • Your doctor or pharmacist will tell you what dose to take. The dose will also be printed on the label of the pack to remind you. As a guide, the dose for an adult or a child over 30 kg (approximately 10 years old) is one tablet, taken 1-3 times a day. If you are giving the tablets to a younger child, check the label carefully to make sure you are giving the correct dose for the weight of your child.
  • Solvazinc® tablets are effervescent, which means that you should dissolve them in a glass of water to take them. Take each dose with a snack or just after eating a meal.
  • If you forget to take a dose, don't worry, just take the next dose when it is due and then carry on as before. Do not take two doses together to make up for a forgotten dose.
  • Try to keep any regular appointments with your doctor. This is so your doctor can check on your progress.
  • If you buy any medicines, please check with a pharmacist that they are suitable to take with zinc tablets. This is because medicines which contain either iron or calcium can interfere with the way zinc is absorbed by your body.
  • If you need any antibiotics for an infection, please make sure that the doctor prescribing them for you is aware that you are taking zinc. This is because zinc supplements can stop some antibiotics from working properly.

Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them. The table below contains some of the most common ones associated with zinc sulfate. You will find a full list in the manufacturer's information leaflet supplied with your medicine. The unwanted effects often improve as your body adjusts to the new medicine, but speak with your doctor or pharmacist if any of the following continue or become troublesome.

If you experience any other symptoms which you think may be due to the tablets, please speak with your doctor or pharmacist for further advice.

  • Keep all medicines out of the reach and sight of children.
  • Store in the original container in a cool, dry place and away from direct heat and light.

This medicine is for you. Never give it to other people even if their condition appears to be the same as yours.
