Q
Hi,would like to ask about ear wax removal. Do you have any ear wax spray for children?
A

You may consider the use of ear cleaning drops such as olive oil ear drop or Audiclean ear wax remover solution to soften the ear wax. Do not try to dig out the earwax using items such as a cotton bud, as you may push the wax further in and injure the ear.

 

Audiclean ear wax remover solution is available on our website here as well.

Please take note that Audiclean ear wax removal solution is not suitable for use in children under 3 years old.

 

If the symptoms do not improve after a few treatments or the ear starts to hurt, please consult a doctor instead.

Q
Recently started on avamys for allergic rhinitis. However, having headaches after starting. Could it be due to Avamys, since it is one of the side effects with relatively high incidence percentage. What do you recommend if it is due to Avamys.
A

Headaches have been reported as a side effect in patients who have used Avamys Nasal Spray. However, headaches may also be caused by other reasons as well. As I am not able to assess the cause for your headaches, you may consult a doctor, especially if the headache is bothering you or if it does not go away. It is important to find out the underlying cause and get appropriate treatment and advice accordingly.

 

If you consider the headache to be mild or occasional, you may also refer to this link for tips to relieve and prevent mild headaches.

Q
Any good vitamin C cream or serum to recommend that is good for aging skin.
A

Vitamin C does not reverse signs of aging such as wrinkles, which develop naturally over time. However, it can help to protect the skin against damage caused by sun exposure. Studies have also found that Vitamin C helps to produce collagen, which helps to keep skin supple and smooth.

 

Vitamin C tends to break down quickly once it is exposed to heat, air and light. Therefore, it is usually manufactured in serum form, which the skin can absorb more efficiently. Ingredients such as Vitamin E and ferulic acid also help Vitamin C to work better.

 

Products which contain 8% of Vitamin C or more are usually more effective. However, do note that higher concentrations above 20% may cause skin irritation and should be used with caution.

Q
What is the difference between elemental calcium, Calcium Carbonate and Calcium Lactate? When you say our body need 1200mg calcium for age between 51 and older, what type of calcium are they referring to? Should it be elemental calcium, calcium carbonate or calcium lactate.

For vitamin K2 (MK-7), what is the daily requirement dosage for age 57 and older years? What happened if we consume over the daily requirement for our age?
A

Elemental calcium refers to the actual amount of calcium in the supplement. There are several types of calcium compounds such as calcium carbonate and calcium lactate that are used in calcium supplements. Each compound contains varying amounts of elemental calcium.

 

Calcium carbonate contains 40% of elemental calcium, while calcium lactate contains 13% of elemental calcium.

 

The daily recommended dietary allowance for women above 51 years old is 1200mg. It refers to the elemental calcium.

 

Vitamin K2 is one of the forms of vitamin K. Vitamin K2 has several forms, MK-4 through MK-13. MK-7 (Menaquinone-7) is one of them. The recommended daily intake of Vitamin K for women 57 years old and above is 90mcg. 

 

As I am not aware of the contents of the supplement that you are taking and your dietary intake, I would not be able to advise you on the dosage required. Please refer to the product packaging for the recommended dosage of the supplement.

 

Excess Vitamin K can lead to Vitamin K toxicity. The effects of Vitamin K toxicity can include
jaundice like symptoms such as dark colored urine or change in skin color, or anemia (a condition with low levels of red blood cells). Although the occurrence of Vitamin K toxicity with oral Vitamin K is rare, it is advisable to follow the recommended daily intake of Vitamin K.
