For thermotherapy, the dilator should be immersed in warm water, ideally at 50° Celsius, for 10-15 minutes.
For cryotherapy, the dilator should be immersed in iced water for 15 minutes in the fridge.
The Dilatan works well regardless of whether the lower bowel is full or empty. In case of spasm, sitting in a warm water bidet prior to insertion will help relax the sphincter muscles and assist the therapy.
Following use, the dilators should be washed in warm, soapy water, thoroughly rinsed and returned to the box when clean and dry.
