Nabilone will add to the effects of alcohol and other central nervous system (CNS) depressants (medicines that make you feel drowsy or less alert). Some examples of CNS depressants are antihistamines or medicine for hay fever, other allergies, or colds; sedatives, tranquilizers, or sleeping medicine; prescription pain medicines, including other narcotics; barbiturates; medicine for seizures; muscle relaxants; or anesthetics, including some dental anesthetics. Check with your doctor before taking any of the above while you are taking this medicine.
If you think you or someone else may have taken an overdose, get emergency help at once. Taking an overdose of this medicine or taking alcohol or CNS depressants with this medicine may cause severe mental effects. Symptoms of overdose include changes in mood; confusion; difficulty in breathing; hallucinations (seeing, hearing, or feeling things that are not there); nervousness or anxiety (severe); and fast or pounding heartbeat.
This medicine may cause some people to become drowsy, dizzy, or lightheaded, or to feel a false sense of well-being. Make sure you know how you react to this medicine before you drive, use machines, or do anything else that could be dangerous if you are dizzy or are not alert and clearheaded.
Dizziness, lightheadedness, or fainting may occur, especially when you get up suddenly from a lying or sitting position. Getting up slowly may help lessen this problem.
Nabilone may cause dryness of the mouth. For temporary relief, use sugarless candy or gum, melt bits of ice in your mouth, or use a saliva substitute. However, if your mouth continues to feel dry for more than 2 weeks, check with your medical doctor or dentist. Continuing dryness of the mouth may increase the chance of dental disease, including tooth decay, gum disease, and fungus infections.
