The following interaction applies only if you are taking ritonavir products (e.G., Norvir, Kaletra) in a solution formulation:

Talk to your doctor before using ritonavir-containing oral solutions together with disulfiram. These ritonavir products are formulated with alcohol, and disulfiram can affect the breakdown of alcohol leading to what is termed a "disulfiram reaction." This condition produces unpleasant side effects such as flushing, throbbing in head and neck, throbbing headache, difficulty breathing, nausea, vomiting, sweating, thirst, chest pain, fast or pounding heartbeats, low blood pressure, dizziness, lightheadedness, blurred vision, and confusion. More severe reactions may include heart attack, heart failure, unconsciousness, and convulsions. You should avoid drinking alcohol while you are being treated with disulfiram. Check your food and medicine labels to be sure those products do not contain alcohol. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
