Electrolyte imbalances
Low levels of potassium or magnesium in the blood should be corrected before starting treatment with Ondamac 4 MG Tablet.
Intestinal obstruction
Use Ondamac 4 MG Tablet cautiously in patients with intestinal obstruction diseases such as colon cancer, Crohn’s disease or diverticulitis because this medicine can delay the time for food to move through the entire intestine (bowel transit time).
Serotonin syndrome
Serotonin syndrome is a condition where your body produces too much of a chemical called serotonin. This occurs when you take medicines that cause high levels of serotonin in your body. This chemical helps your brain cells and nerve cells to communicate with each other. But too much serotonin causes extreme nerve cell activity and serious symptoms. Caution should be taken when Ondamac 4 MG Tablet is used along with other same class of medications like granisetron, dolasetron, etc., as it may increase the risk of serotonin syndrome.
