About zinc sulfate tablets
|Type of medicine||A mineral|
|Used for||Zinc deficiency|
|Also called||Solvazinc®; AadZinc®|
|Available as||Effervescent (dissolvable) tablets|
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.
Before taking zinc sulfate tablets
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 breastfeeding.
- If you have any problems with the way your kidneys work.
- If you have been told you have a copper deficiency.
- If you are taking or using any other medicines. This includes any medicines you are taking which are available to buy without a prescription, as well as herbal and complementary medicines.
- If you have ever had an allergic reaction to a medicine.
How to take zinc sulfate tablets
- 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.
- Zinc sulfate 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.
Getting the most from your treatment
- 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.
