“For several years I have suffered from Uveitis and Macula Odema in one eye. The Macula Odema has settled but the Uveitis is only controlled with Corticosteroid eye drops. I tried to gradually reduce the corticosteroid drops and replace them with the carnosine, but this was not entirely successful and after a visit to the Specialist I am back using the coticosteroid drops. I didn't know whether it would be of any value to use both at the same time. What the Carnosine did do was reduce the pressure and as both my parents had glaucoma I am very conscious of the need to keep the pressure down. So I may need to use the carnosine for that in the future and of course I realize that extended use of the steroid drops can cause cataracts.”
You can buy some topical corticosteroids "over-the-counter" without a prescription. For example, for dermatitis, you can buy the steroid cream called hydrocortisone 1% from your pharmacy. Do not apply this to your face unless your doctor has told you to do so. This is because it may trigger a skin condition affecting the face ( acne or rosacea. ) Long-term use may also damage the skin. On your face this would be more noticeable than the rest of your body. So usually only weak steroids are used on the face. Those which are suitable are prescription-only.
