Unauthorized health products seized from stores in the Greater Toronto Area because they may pose serious health risks

Aminocaproic acid: This is a prescription drug ingredient used to decrease bleeding in various clinical situations. Exposure to aminocaproic acid in the eye may affect the eye itself, and the acid may be absorbed through the tear ducts into the blood. Side effects may include watery eyes, vision changes, headache, dizziness, nausea, muscle weakness and skin rash.

Neostigmine methylsulfate: There are no approved eye drops containing neostigmine methylsulfate on the Canadian market. In the past, drugs similar to neostigmine were used to treat glaucoma. These medications are no longer widely used because of the significant number of potential eye-related side effects, including blurred distance vision, frontal headaches, twitching lids, red eyes, cataracts, allergic reactions, iris cysts, retinal detachment and the potential for causing a specific type of glaucoma attack. In addition, absorption into the nose via the tear duct may cause serious cardiac and respiratory side effects.

Prednisolone valerate acetate is a prescription corticosteroid drug available in Canada as eye drops used to treat inflammation of several parts of the eye. It has not been approved for use in creams in Canada. Common side effects for topical corticosteroids include skin atrophy (thin and fragile skin with reduced elasticity), skin blood vessel changes (e.g., spider veins), changes in skin colour, stretch marks, swelling, dry skin, burning sensation, local irritation, rash, redness, itching, thinning hair or excessive hair growth, infections and allergic reactions. Topical corticosteroids absorbed through the skin may cause side effects throughout the body, especially when used over a large surface area and for a long time. This risk is greater in children, who may absorb proportionally larger amounts and be more susceptible to side effects. Systemic side effects could include high blood pressure, high blood sugar, blurred vision, uneven heartbeats, weakness, and swelling. Prednisolone acetate should not be used in patients who are allergic to prednisolone acetate or to any ingredient in the formulation. Prednisolone acetate is not to be used in children and is not recommended for use during pregnancy or breastfeeding.

Tranexamic acid is a prescription drug used to prevent or reduce bleeding by slowing the breakdown of blood clots. The drug is usually administered by mouth or intravenously. Tranexamic acid should be used with caution with blood thinners and anti-inflammatories, estrogen therapy, medicines used to help blood clotting, birth control pills, hydrochlorothiazide, desmopressin, ranitidine, or nitroglycerin.
