Product Q&A (From Daiichi Sankyo Healthcare official website)

QWhat are the features of Oirax DX Ointment?

AIt contains six active ingredients including steroids and anti-inflammatory agents, providing excellent effects for various troublesome skin symptoms such as eczema, rashes, and itching. Suitable for the whole family from children to the Elderly. It is a low-irritation ointment that firmly protects the affected area and can be used on a wide range of skin conditions from weeping to dry skin.

QPlease explain how to differentiate the use of Oirax DX Ointment and Oirax A.

AOirax DX Ointment is a low-irritation ointment that protects the affected area, while Oirax A is a Cream with good spreadability. Due to the strength of the steroid ingredients, Oirax DX Ointment is recommended for severe symptoms like itching. For relatively wide affected areas, Oirax A is recommended.

QIt says "Do not use for a long time," but how long is considered long?

AUse for about two weeks as a guideline. Avoid prolonged and indiscriminate use as it may cause side effects. Stop use once symptoms improve. If symptoms do not improve after 5 to 6 days of use, stop using and consult a doctor, pharmacist, or registered seller.

QIt says consultation is necessary for "people with wide affected areas," but how large is considered wide?

AA wide area is approximately the size of two palms of the user’s hand. If the affected area is wide, be careful as applying a large amount may cause side effects due to percutaneous absorption.

QHow is the potency of steroid topical agents like Oirax DX Ointment classified?

AThe drug selection by doctors is classified into five groups. They range from the strongest "Strongest" to the weakest "Weak." Dexamethasone acetate contained in Oirax DX Ointment is classified as "Weak," but it is difficult to evaluate and classify topical agents based solely on the main active ingredient. The drug's effect may vary depending on the application site, concentration of ingredients, and composition of the base.

Oillux DX Ointment — The answer to “heal faster and more completely”

The Oillux brand, which has addressed itching for over 60 years, developed the “Oillux DX Ointment” in 2019. While previous series focused mainly on “suppressing itching,” the DX ointment aims to combine five approaches in one: calming inflammation, suppressing itching, sterilizing, repairing skin, and improving blood flow. The combination of steroid ingredient (dexamethasone acetate) and non-steroidal anti-inflammatory ingredient (glycyrrhetinic acid) provides a dual approach to inflammation, while crotamiton directly blocks itching. Additionally, with three ingredients for skin repair, sterilization, and blood flow improvement, this is the Oillux formula with the most ingredients ever, suitable for the whole family from babies to the elderly.
