Why is this medication prescribed?

Dronabinol is used to treat nausea and vomiting brought on by chemotherapy in patients who have tried other drugs for this condition without success. Acute immunodeficiency syndrome patients with loss of appetite and weight loss can also be treated with dronabinol (AIDS). A group of drugs known as cannabinoids includesdronabinol. It affects the part of the brain that manages hunger, nausea, and vomiting.

How should this medicine be used?

Dronabinol is available as a liquid solution and a capsule to swallow. To relieve nausea and vomiting brought on by chemotherapy, dronabinol capsules and solution are often taken 1 to 3 hours prior to chemotherapy, followed by every 2 to 4 hours after chemotherapy, for a total of 4 to 6 doses per day. The following dosages can be taken with or without food, but the first dose of the solution should typically be given on an empty stomach at least 30 minutes before eating. Usually taken twice daily, one hour before lunch and dinner, dronabinol capsules and solution are used to enhance appetite. Ask your doctor or pharmacist to explain any instructions on your prescription label that you do not understand, and carefully follow their instructions. Just as prescribed, take dronabinol.

Do not chew or crush the capsules; instead, swallow them whole.

With a full glass of water, swallow the dronabinol solution (6 to 8 ounces).

To measure your dose, always use the oral dosing syringe that is included with the dronabinol solution. If you’re unsure of how to measure your dose of dronabinol solution, see your physician or pharmacist.

You’ll likely start taking dronabinol at a low dose prescribed by your doctor, who may then gradually raise it. If you suffer adverse effects that do not go away after 1 to 3 days, your doctor might also lower your dose. Throughout your dronabinol treatment, be sure to let your doctor know how you are feeling.

A dependence ondronabinol could develop. Don’t take the medication in excess of what your doctor has suggested in terms of dosage, frequency, or duration. If you discover that you desire to take additional medication, call your doctor.

Just as long as you continue to take the drug willdronabinol keep your symptoms under control. Dronabinol should still be used even if you feel fine. Without consulting your doctor, never discontinue taking dronabinol. You can suffer withdrawal symptoms if you abruptly stop using dronabinol, including irritability, trouble falling or staying asleep, restlessness, hot flashes, sweating, runny nose, diarrhoea, hiccups, and lack of appetite.

What special precautions should I follow?

Before taking dronabinol,
