There has been a recent shortage of the short acting Methylphenidate medication in Canada. This is listed on the website DrugShortages.ca (and you can visit that site to check if the shortage is still an issue).
Methylphenidate is a stimulant medication used to treat ADHD. It is the active ingredient in the following medications: Ritalin, Ritalin SR, Biphentin and Concerta. However, the only form of this medication which is impacted by the shortage is the short acting version. Specifically, the 10 mg tablets, and the 20 mg tablets.
This shortage does not impact the availability of the long acting versions of methylphenidate such as Biphentin and Concerta.
Although it’s generally recommended that the long acting medications (such as Concerta and Biphentin) should be used to treat ADHD, as they work better for individuals with ADHD, there are still occassions that doctors will use a short acting stimulant medication.
These could include:
- Using a long acting methylphenidate medication in the morning and then taking a short acting in the evening when it has been a particularly long day (i.e. topping up the medication for night school)
- When a teen sleeps in on the weekend and gets up too late to take a long acting medication, they may take a short acting mid-day on the weekend to have some stimulant treatment
- There are some patients (in my experience this is very few) who don’t do as well with a long acting medication as they do with a short acting version
If you or your child is taking a short acting version of Methylphenidate, you may have a hard time refilling the prescription. The pharmacist will likely tell you that the product is ‘back ordered’. However, if the pharmacy still has stock on their shelves, then you should be able to fill the prescription.
Here’s what you can do if you are stuck and cannot refill your prescription for methylphenidate:
- Ask the pharmacist to call other pharmacies to see if they have stock on their shelves (i.e. they will be able to call other pharmacies in their ‘chain’ (such as Shopper’s Drug Mart) and if another pharmacy has stock, they may be able to get it for you)
- Phone other local pharmacies and see if they have stock on their shelves, and then take your prescription to that pharmacy (you would have to take an actual prescription, as pharmacies cannot transfer prescriptions for methylphenidate from one pharmacy to another).
- Check if your pharmacy can order in the 5 mg tablet of Methylphenidate. If they are able to, contact your doctor’s office and explain that you need the doctor to change the prescription to the 5 mg tablets because of the medication shortage.
If none of these strategies work, then be sure to see if you can take either of Biphentin, Concerta, or even Ritalin SR to see if they can help you. Alternatively, you may benefit from a trial of an amphetamine medication – such as Vyvanse, Adderall XR, or Dexedrine. That would be an issue you’ll have to discuss with your doctor.
Please share any experiences you’ve had – particularly if you have a strategy which could be helpful to others.
