You have mentioned two branded medications suggested by your doctor. The first, Omnacortil, has the active ingredient prednisone, which is a corticosteroid hormone used as an anti-inflammatory agent. The second, Teczine, has levocetirizine, an antihistamine that is used to treat allergies.
In combination with your symptoms, it would appear you are suffering from an allergic skin condition. In your particular case, it seems that sunlight triggers the condition, causing the "strange problem" of itching. In many such cases, the root problem can be traced back to dry skin, which is especially sensitive to ultraviolet (UV) radiation in sunlight. The intensity of the condition is best determined by your doctor. If you are observing any skin inflammation and a burning sensation, you may have psoriasis, a long-term problem that is difficult to treat. If the symptoms are limited to itching with some skin peeling or flaking off, it may be a form of dermatitis, such as eczema. You have also mentioned that your symptoms are present for over two months, which could mean a long-term problem. Do not discontinue the medication; it may not feel like it, but it could be helping in preventing the condition from spreading or getting worse.
To supplement the prescription drugs, you can start a skin care program that will reduce the dryness of your skin. This can help to make your skin less sensitive, which may reduce the symptoms or even cure the skin problem. In your case, you must start using a good quality sunscreen on all the exposed parts of your body. The minimum recommended sun protection factor (SPF) is 15, but try a product with better protection. At home, use aloe vera gel on the areas that itch. Aloe vera is soothing to the skin, reducing the itching sensation. It also helps to trap natural moisturizing skin oils, reducing the dryness of the skin. Finally, it has excellent antimicrobial properties to fight any secondary infections that may attack the inflamed, sensitive skin. During your shower or bath, avoid hot water. Add a few tablespoons of baking powder and cornstarch to a lukewarm bath; this provides relief from the itching sensation and helps the skin heal itself. A few drops of tea tree oil will also provide good protection to your skin. Dry your skin using a towel to pat it, rather than harsh rubbing motions. A moisturizer with natural ingredients would also be useful in dealing with your dry skin. Use clothing of natural fibers such as cotton to avoid irritating the skin.
