Good evening doctor, is it permissible to use vitamin A without doctor’s advice (taken once a week)?

1 Answer:

Good morning Decha KT, thank you for asking on HealthReplies.com.

Vitamin A is a vitamin that is important for vision, growth, cell division, reproduction and also the body's immunity. This vitamin can be found in many food sources such as spinach leaves, dairy products, liver, green vegetables and carrots.

While vitamin A supplementation is only given to people who do not consume enough food that contains vitamin A or have certain conditions that do require more vitamin A than others, such as certain eye diseases, pancreatic organ diseases and measles.

Although eye disorders are included in one of the conditions recommended for taking vitamin A supplementation, not all eye diseases require this supplementation. Therefore it is highly not recommended for you to take vitamin A supplements at a dose that is decided on your own and without a clear recommendation from a doctor just because you have a complaint in the eye, because it is not necessarily the cause of complaints in your eye due to conditions that require vitamin A therapy. Therefore also, it is advisable for you to check the condition of your eyes first to an ophthalmologist to determine what causes complaints in your eyes and then the doctor will decide whether your eye condition requires supplementation of vitamin A or not, and if necessary how the dose which should be consumed.

Also note that vitamin A has a daily limit for consumption because this vitamin can provide some side effects that may be dangerous in certain conditions. Vitamin A is only recommended for consumption of 3000-10,000 IU per day, if it exceeds this dose, it can cause side effects such as:

Bone thinning Damage to the liver Headache Diarrhea Nausea Irritation of the skin Pain in bones and joints Disability in the fetus (especially blah consumed during pregnancy) For now, stop supplementing vitamin A first, and replace it by consuming foods that contain lots of vitamin A as mentioned above. It is highly recommended not to take any supplements if there is no clear recommendation from a doctor.

I hope this helps.
