Dear Health Care Professional,

NCESAMET® (nabilone) is a synthetic cannabinoid with antiemetic properties which have been found to be of value in the management of some patients with nausea and vomiting associated with cancer chemotherapyFootnote 1. Trazorel (trazodone hydrochloride) is a psychoactive compound with sedative and antidepressant properties and is of value in the symptomatic relief of depressive illnessFootnote 2.
Due to a mislabelling incident, a bottle containing CESAMET CAPSULES 1 mg bearing one of the lot numbers and expiration dates in the above table was labelled as TRAZOREL 50 mg TABLETS.
For this reason, Valeant Canada Limited, in consultation with Health Canada, is advising healthcare professionals of a recall involving CESAMET 1 mg Capsules (bottles of 50 capsules) and TRAZOREL 50 mg Tablets (bottles of 100 tablets), with the above lot numbers and expiration dates.
A similar notice has been forwarded to all wholesalers distributing for Valeant Canada Ltd.
Patients taking either of these medications have been provided with the description and pictures of the two involved products through a public warning and are being advised to check their prescription bottles immediately to ensure that they contain the correct product. If not, they have been advised to contact their treating physician immediately and return the product to the pharmacy. Trazorel comes in round, peach-colored tablets engraved with ICN T21. Cesamet is sold in blue and white capsules with the number 3101 imprinted on the white part of the capsule and the ICN logo on the blue part of the capsule. Please see pictures of the two products on the last page of this letter.
The following is recommended:
- Pharmacists are asked to contact any patient to whom these lots of Cesamet or of Trazorel may have been prescribed in order to confirm the appearance of the product in their bottles and ensure that patients have been given the correct product. In case of any doubt the patient should be requested to bring the product to the pharmacy for verification.
- If there is any doubt or if the patient has received a product in error, the patient must advise their health care professional immediately.
- Physicians are requested to remain available for patients who will be contacting them under the circumstances.
The most important medical risks of inadvertently taking nabilone instead of trazodone are:
- The usual daily maintenance dose of trazodone is 300 mg divided in 2-3 doses per day. As a consequence, due to this mislabelling, the patient might take 6 capsules of nabilone 1 mg (believing it to be trazodone) totalling 6 mg/day instead of 6 tablets of trazodone 50 mg divided in 2-3 doses per day. The maximum recommended daily dose of nabilone is 6 mg in divided doses (twice a day). Therapy with nabilone requires dose adjustment for the purposes of response and tolerance in individual patients. Symptoms of overdose such as hallucinations, anxiety reactions or respiratory depression may occur if a patient is exposed acutely to 6 mg of nabilone in divided doses without dose adjustment. Also accidental exposure to nabilone 6 mg increases the risk of developing psychotropic reactions that can persist for 48 to 72 hours following cessation of treatment.
- The most frequently observed adverse reactions to nabilone are: drowsiness, vertigo, euphoria, dry mouth, depression, ataxia, blurred vision and dysesthesias. A depressed patient taking nabilone instead of his (her) usual antidepressant treatment is susceptible to becoming more depressed given the potential for depression associated with nabilone.
- Nabilone is contraindicated in patients with known sensitivity to cannabinoids or history of psychotic reactions.
