1. What A-Vite is and what it is used for

Your doctor has prescribed you A-Vite to prevent or treat situations where there is a lack of vitamin A.

Vitamin A is a liposoluble vitamin playing an important role in the organism, namely in the retina.

The deficiency in vitamin A causes disturbances in the visual adaptation to dark, as well as degenerative changes in the retina.

Given its role in the maintenance of the structural and functional integrity of the epithelial cells, the deficiency of vitamin A is accompanied by the atrophy of these cells and keratinization which, as far as skin is concerned, causes the appearance of dry skin and scaling.

A decrease in the resistance to infections is also observed.

The intake of vitamin A normalizes the changes caused by its deficiency, exception made regarding irreversible eye injuries.

2. What you need to know before you take A-Vite

Do not take A-Vite

– if you are hypersensitive (allergic) to vitamin A or to any other ingrediente of A-Vite,

– if you have hypervitaminosis A (excess of vitamin A),

– if you are pregnant or breastfeeding,

– if you are taking any of the following medicines:

– cholestyramine or colestipol

– neomycin – retinoids (isotretinoin, etretinate)

– warfarin (only if you are taking very high doses of A-Vite)

Take special care with A-Vite

Talk to your doctor on any health problems you may have or may have already had and about your allergies.


The use of A-Vite in children must be handled with precaution as children have greater sensitivity to high doses and/or to the prolonged administration of vitamin A.


In the elder, the prolonged administration of A-Vite may come with a greater risk of vitamin A overload due to a decrease in the clearance of this substance.

Taking A-Vite with other medicines

Tell your doctor of pharmacist if you are taking, have recently taken, or might take any other medicines including those obtained without prescription. You should also tell any other doctor prescribing you new medication that you are taking A-Vite.

Taking A-Vite together with any of the following medicines may interfere with the absorption of vitamin A and that is why it is so important to tell your doctor if you are taking cholestyramine, colestipol or neomycin.

The administration of certain medicines with A-Vite may lead to adverse reactions that are additive given the interaction with vitamin A. This being so, always tell your doctor if you are taking retinoids (isotretinoin, etretinate).

It is also important to inform your doctor if you are taking anticoagulants (medicines that prevent blood clots, such as warfarin, for instance) since high doses of Vitamin A may increase its effects.

Pregnancy and breastfeeding

Always ask your doctor or pharmacist for advice before taking any medicine.

A-Vite must not be taken by pregnant women, women planning on having a baby or women thinking they might be pregnant. If you get pregnant during treatment with A-Vite, stop treatment and immediately talk to your doctor.

Women who are breastfeeding must not take A-Vite.

Driving and using machines

A-Vite is not likely to interfere with the ability to drive and use machines.
