Ingredient Sensitivities in Medications

Some people react to certain ingredients in commercial medications, such as dyes, gluten-containing starches, lactose, preservatives or flavourings. Reactions range from mild stomach upset to serious allergic reactions.

If you suspect an ingredient is causing problems, tell your pharmacist and prescriber. They can check the full ingredient list of the product you take and help decide what to do next.

Where Compounding May Fit

Commercial products list their inactive ingredients, and those cannot be changed. When a prescriber writes a prescription for a compounded preparation, our pharmacists can choose ingredients to avoid a specific one the prescriber names, where a suitable alternative exists. This is a decision for you and your prescriber, and it is not always possible.

Compounding is not a first step and not a substitute for an assessment. Whether a compounded preparation is appropriate is your prescriber’s decision, made after considering your history and the commercial products already available.

Please note: We do not promote specific compounded preparations or ingredients to the public. Your prescriber decides what, if anything, to prescribe.

Questions to Bring to Your Appointment

  • Which ingredient do you react to, and how was it identified?
  • What symptoms do you have, and how soon after taking the medication?
  • Which medications are you taking, and in what form?
  • Are there other allergies, such as to foods, latex or other medications?
  • Have you been assessed by an allergist?

When to See a Prescriber Promptly

Call 911 for difficulty breathing, swelling of the face or throat, or a widespread hives rash after taking any medication. See a physician or nurse practitioner for repeated mild reactions or suspected intolerance. This page is educational and does not replace a medical assessment.

Dye-Free, Gluten-Free and Allergen-Free Medications FAQ

Can a pharmacy compound a preparation for dye-free, gluten-free and allergen-free medications without a prescription?

No. A compounded preparation is made against a prescription from an authorized prescriber such as a physician or nurse practitioner.

Can every ingredient be avoided?

Not always. Some ingredients are needed for the preparation to be made or to stay stable. Your prescriber and pharmacist can discuss what is possible.

Should I stop my medication if I suspect a reaction?

Do not stop a prescribed medication without speaking to your prescriber or pharmacist, unless you are having a severe reaction, in which case call 911.

Does insurance cover compounded preparations?

Coverage varies by plan. Call us with your prescription and we will check what your plan allows before preparing it.

How long does preparation take?

Many preparations are ready within 24–48 hours of receiving a complete prescription, though timing depends on the preparation and ingredient availability. We will confirm when you call.

Do you offer delivery?

Yes, we deliver across the GTA. Call (647) 348-2323 for details and timing.

When should I contact my prescriber or pharmacist?

Contact them if you notice a reaction, new symptoms or questions after starting a prescribed preparation. For difficulty breathing or swelling of the face, call 911.
