Drug shortages can occur for a variety of reasons.The factors currently affecting drug supply are shortages of raw materials, quality control issues which led to voluntary withdrawal and longer production times for some products and competition among drug manufacturers. The problem is expected to ease somewhat with renewed production in some cases and takeover of supply by another company in others. For more details see the environmental scan on Drug Supply Disruptions recently posted on the CADTH website.

In the meantime, healthcare providers are responsible for ensuring patients continue to receive appropriate drug therapy. A general protocol to follow in handling drug shortages is offered below:

  1. Ensure there is a valid indication for the drug. Review the patient’s drug and medical history. For a checklist of criteria to consider, check the CPhA Drug Shortages Guide pg 4 - 6.
  2. Substitution of a different brand of the same drug (molecule):
    • Check the Saskatchewan Prescription Drug Plan (SPDP) Formulary for interchangeable brands of the same drug; then check for availability of these brands. (Call wholesalers, manufacturers)
    • If none are available, is there a non-interchangeable brand of the same the same dosage form? Obtain authorization for substitution from doctor, start at same dose or a reduced dose and titrate to desired effect (especially important if drug has a narrow therapeutic index) and monitor for beneficial and adverse effects. Follow-up with the patient in 24 – 48 hours, as indicated by kinetic and pharmacologic characteristics of the drug.
    • If no Formulary drug in the same dosage form is available, check Health Canada Drug Product Database for other brands that may be available and proceed as above.
    • If none available, is there a different dosage form of the same drug? Obtain authorization for substitution from doctor, start at appropriate dose and titrate to desired effect (especially if narrow therapeutic index) and monitor for beneficial and adverse effects. Follow-up with the patient in 24 – 48 hours as indicated by kinetic and pharmacologic characteristics of the drug.
    • If no Formulary drug is available, check Drug Product Database for other dosage forms that may be available and proceed as above.
    • As necessary, consult SPDP regarding coverage for substituted brand.
  3. If no other forms of the same molecule are available, substitution of another drug in the same therapeutic class can be considered. Check the references below for dose equivalence data. This information is not always available. Even when a therapeutically equivalent dose is administered, patients may react differently. Pharmacists should follow-up with the patient frequently until the patient is stabilized on the new medication.
    • Rx Files Charts -
    • e-therapeutics + (available at SHIRP)
    • Handbook of Clinical Drug Data , 2010, 11th edition - hardcopy text
  4. If there is not a therapeutic equivalent, check treatment guidelines and recommend a drug from another pharmacologic class. Monitor and titrate to desired effect.
  5. Compounding capsules or tablets in the desired doses when other strengths of drug are available or from bulk powders may be another option, especially in instances where there is not a readily available or acceptable substitute.

In order to provide greater information to health care practitioners and the general public, Canada’s Research Based Pharmaceutical Companies (Rx&D) and the Canadian Generic Pharmaceutical Association (CGPA) began collecting information on behalf of their individual member companies on current and impending drug shortages in the fall of 2011. Rx&D has now turned over its database architecture (i.e. the former Rx&D Drug Shortages Database) and opened its use to non-Rx&D members (i.e. all market authorization holders) who are authorized to sell medicines in Canada, and who may need to use the site to report a drug shortage.  Iinformation is being provided on a voluntary basis.  It does not necessarily include all pharmaceutical companies in Canada, and therefore there may be gaps in the data. The new database is called the Canadian Drug Shortages Database:

The following tables provide suggestions for handling shortages of specific drugs. This information is intended for use by healthcare providers for general informational purposes only.  It remains the responsibility of the healthcare provider to use professional judgment in evaluating this information in light of any relevant clinical or situational data.  This information is provided without warranty of any kind and medSask and the University of Saskatchewan assume no responsibility and/or legal liability whatsoever for any errors, omissions or inaccuracies contained therein.
