- Background Information
Drug shortages can occur for a variety of reasons and may include, but are not limited to, shortages of raw materials, quality control issues which lead to voluntary withdrawal and longer production times for some products, and competition among drug manufacturers. For more details see the Multi-Stakeholder Toolkit (last revised 2017).
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:
- Confirm that the drug is shorted. For certain drugs, manufacturers are required by law to report anticipated and actual drug shortages and discontinuations. These reports are available and searchable at www.drugshortages.ca.
- 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.
- 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 drug in the same dosage form? Obtain authorization for substitution from prescriber, 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 the 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 prescriber, start at appropriate dose, titrate to desired effect (especially if narrow therapeutic index), and monitor for therapeutic 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 the Health Canada Drug Product Database for other dosage forms that may be available and proceed as above.
- As necessary, consult SPDP regarding coverage for substituted product.
- 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.
- If there is not a therapeutic equivalent, check treatment guidelines and recommend a drug from another pharmacologic class. Monitor and titrate to desired effect.

- We have compiled some helpful tips on how to administer adult formulations (whole/opened/split/crushed) to children.
- Ensure duration of therapy is appropriate. See CPhA's Optimizing Duration of Therapy: Is Shorter Smarter?

Several brands/strengths of estradiol patches are shorting. All strengths of Oesclim® have been discontinued.
- Estradot® and Sandoz-estradiol patches are interchangeable.
- Estradot® and Climara® patches are NOT considered interchangeable by the SK drug plan.
- Climara® patches are changed once weekly; Estradot® patches are changed twice weekly.
- While cutting transdermal patches is not ideal, it is acceptable for matrix patches of medications with wide therapeutic indices (all of the estradiol patches are matrix).
- There are limited data regarding stability of cut patches, but some data of estrogen patches (not necessarily the same products available here) suggests cut patches maintain concentrations when returned to the original pouch and stored at labeled storage conditions for up to 1 month after cutting. It seems reasonable to apply this data to all estrogen matrix patches.
- Cutting square and rectangular-shaped patches on the diagonal may result in more even doses. Considering many people use estrogen patches for symptomatic treatment, dosage accuracy may not be critical, but something to keep in mind if symptoms are not controlled as well using cut patches.
- Estradiol gel is another transdermal option.
- See RxFiles Postmenopausal Therapy for more information. RxFiles is available through SHIRP.

Nitrofurantoin
- Nitrofurantoin BID 100 mg capsules (macrocrystal/monohydrate): return to stock date: mid-October/24
- Nitrofurantoin 50 mg capsules (macrocrystal) - expected availability: mid-October/24
- Nitrofurantoin 100 mg capsules (macrocrystal) - indeterminate availability
- Nitrofurantoin 50 mg tablets - Available
- Nitrofurantoin 100 mg tablets - Available
Note the differences in dosing frequency among the different nitrofurantoin forms:
- BID nitrofurantoin products (original brand MacroBID®), including PMS-Nitrofurantoin BID, contain nitrofurantoin as macrocrystals (25%) and monohydrate (75%). Nitrofurantoin monohydrate (but not macrocrystals) forms a gel matrix when exposed to intestinal fluids. This matrix releases nitrofurantoin over time, which allows for twice daily dosing.
- AA Pharma Nitrofurantoin tablets and Teva-Nitrofurantoin capsules do not contain monohydrate and need to be administered four times daily.
- Dosing of these products for treatment of cystitis is 50 mg to 100 mg, four times daily. 50 mg four times daily has been found to be as effective as 100 mg twice daily of the BID product and is appropriate in most situations. If the only product on hand is 100 mg, go with that (QID).
See CPS - Nitrofurantoin (CPhA Monograph) for dosing of all nitrofurantoin products. CPS is available through SHIRP.

Potassium chloride (Slow-K®)
Slow-K® (NPN 80040226) 600 mg KCl (8 mEq K+) slow release matrix tablets and Sandoz/Euro K8 (DIN 02246734) have been discontinued.
Alternative long-acting tablets providing 8 mEq K+:
- Jamp K-8 (NPN 80013005) 600 mg long acting tablet
- M-K8 (NPN 80035346) 600 mg long acting tablet
- PRZ-K8 (NPN 80108882) long acting tablet
- Please note that there are supply challenges with all brands and only intermittent availability.
Note: These products contain the same strength of KCl in a similar dosage form to Slow-K® and Sandoz/Euro K8 and are the closest alternatives. However, the products are not interchangeable. If patient is near the high or low ends of the potassium reference range or if patient has a history of frequent fluctuations, closer monitoring after transition is prudent.
Note: Inventory of the above products seems to fluctuate frequently.Alternative solid dosage forms providing 8 mEq K+:
- Jamp Potassium Cl ER 600 mg capsules (NPN 80062704)
- Please note that there are supply challenges with all tablet and capsule formulations of potassium chloride and availability is intermittent
Note: These capsules contain the same strength of KCl in a different, yet still modified release, dosage form. If patient is near the high or low ends of the potassium reference range or if patient has a history of frequent fluctuations, closer monitoring after transition is prudent.
Alternative liquid providing 1.33 mEq/ml KCl+:
- Odan-Potassium Chloride (NPN 80046782)
- Jamp KCl liquid (NPN 80024835)
- PMS KCl liquid (DIN 02238604)
Note: Because the absorption pattern will be quite different between Slow-K®/ other long-acting oral KCl tablets and the liquid, closer monitoring of all patients after transition is prudent.
Alternative long-acting tablets providing 20 mEq K+:
- Sandoz-K 20 (NPN 02242261)
- Odan K-20 (NPN 80004415)
- JAMP K-20 (NPN 80013007)
- PRZ K20 (NPN 80107649)
- Please note that there are supply challenges with all brands and availability is intermittent
Note: K-Dur tablets are no longer available, but were scored, sustained-release tablets that could be broken in half or dispersed in water. Though Sandoz K-20 tablets (NPN: 02242261) are also scored, sustained-release tablets, Sandoz suggests that K-20 long-acting tablets should not be split and must be swallowed whole to retain their sustained-release properties. Jamp Pharma confirmed that dividing their K-20 tablets (NPN: 80013007) would compromise the sustained-release properties of the tablets. This could be clinically significant as modified release formulations slow the release of potassium to avoid high local concentrations which may lead to gastric irritation. (Note: modified release solid dosage forms have been associated with a low risk of GI ulceration/bleeding in some circumstances and caution is necessary in people with delayed GI transit or impaired GI motility.) Splitting tablets may also lead to dose inaccuracy.
