Why this happens
Allopurinol works by lowering uric acid levels in the blood, while nortriptyline is a tricyclic antidepressant that affects brain chemicals. They are processed by different pathways in the liver and do not interfere with each other's absorption or excretion.
What you should do
You can safely take these two medicines together. As with any new medication, if you notice unusual skin rashes, yellowing of the eyes or skin, or persistent sore throats, you should contact your doctor. Always ensure your doctor knows all the medicines you are taking.
