Detrol LA and Tolterodine Extended-release at CanadaPharmacyOnline

The brand name Detrol LA, manufactured by BGP Pharma, is available in Canada.

Generic tolterodine extended-release is sourced from manufacturers that meet applicable regulatory standards. The specific manufacturers of your dispensed medication may vary.

Important Information about Generic Tolterodine Extended-release

Generic tolterodine extended-release contains the same active ingredients as brand-name Detrol LA and is required to meet the same safety, effectiveness, and quality standards. This means that it is designed to work in the same way as Detrol LA. Studies have shown that generic paroxetine is bioequivalent to brand-name Detrol LA, meaning they have similar absorption rates and reach similar concentrations in the bloodstream. However, individual responses to medication can vary due to factors such as metabolism, genetics, and other health conditions.

For more information about generic drug approval and bioequivalence, you can visit the FDA website: https://www.fda.gov/drugs/generic-drugs/generic-drug-facts.

Dosage:

The brand name Detrol LA is available in 4 mg extended-release capsules. Tolterodine, the generic version of Detrol LA, is also available in 2 mg and 4mg extended-release capsules.

Your doctor will determine the appropriate dose based on your individual needs and medical conditions.

Usage:

Detrol LA is the long-acting, extended-release version of Detrol. It is prescribed for the treatment of symptoms of overactive bladder, including frequent urination, urgency, and urge incontinence (leakage).

Mechanism of Action:
Detrol LA (tolterodine) is a medication that helps with an overactive bladder by relaxing the muscles in the bladder wall. When you need to urinate, a signal is sent to your bladder muscles, causing them to contract and release urine. For people with an overactive bladder, these signals are too strong or occur too often, causing a sudden urge to go to the bathroom. The active ingredient in Detrol LA, tolterodine, blocks these signals from reaching the bladder muscles. By doing this, it helps calm the bladder and reduces the number of uncontrolled contractions, allowing for better control over urination.

Take Detro LA exactly as prescribed by your doctor, following the instructions in the product monograph in Canada. Consult your doctor for personalized guidance and safe use.

The information below summarizes some, but not all, potential side effects, risks, and interactions. Before taking Detrol LA, it is essential to discuss all possible side effects, risks, and interactions with your doctor or pharmacist.

Side Effects:

The information below outlines potential side effects of Detrol LA (tolterodine). It is not an exhaustive list, and individual reactions can vary.

Common side effects – The following are some common side effects of Detrol LA (tolterodine); other side effects may also occur. Contact your doctor promptly if any side effects are persistent, worsening, or concerning, or if you experience any other concerning symptoms.
• Constipation
• Dizziness
• Dry mouth
• Dry eyes
• Headache
• Stomach pain

Other Potential Side Effects (less common):
• Back pain
• Blurred vision
• Drowsiness
• Fatigue
• Indigestion
• Joint pain
• Sore throat
• Urinating less than usual

Serious Side Effects: These are rare but potentially severe side effects. Seek immediate medical attention or call emergency services if you experience any signs of an allergic reaction, such as:
• Cardiovascular Effects: Fast or irregular heartbeat (palpitations), chest pain, or severe dizziness that may indicate a serious heart rhythm problem.
• Central Nervous System Effects: Hallucinations, confusion, or changes in mental state.
• Eye Pain or Vision Changes: This could be a sign of narrow-angle glaucoma.
• Gastrointestinal Obstruction: Severe stomach pain with constipation, indicating a potential blockage.
• Signs of severe allergic reaction (anaphylaxis or angioedema): Swelling of the face, lips, tongue, or throat; hives; severe rash; or difficulty breathing.
• Swelling: Swelling in your hands, ankles, or feet.
• Urinary Retention: Inability to urinate at all or passing very little urine.

Contraindications:

The following is not an extensive list of contraindications. Before taking Detrol LA, it is crucial to discuss all your medical conditions, past and present, and all medications you are taking with your doctor or pharmacist.

Detrol LA should not be used if you have:
• A history of angioedema after taking tolterodine or fesoterodine.
• A stomach condition that causes delayed emptying.
• Uncontrolled narrow-angle glaucoma.
• An inability to empty your bladder (urinary retention).

Tell your doctor about all of your medical conditions, past and present, before starting Detrol LA. This is crucial because conditions can affect whether Detrol LA is proper for you. These conditions may include, but are not limited to:
• Bladder obstruction
• Gastrointestinal obstructive disorders (e.g., severe constipation)
• Heart disease, including irregular heartbeat, heart failure, or a condition called QT prolongation
• Kidney problems
• Liver problems
• Myasthenia gravis (a muscle weakness disorder
• Urinary tract obstruction

Drug Interactions:

Before taking Detrol LA, it is essential to discuss all potential risks and interactions with your doctor or pharmacist. For complete and up-to-date information, please visit the official prescribing information from Viatris Canada at https://www.viatris.ca/-/media/project/common/global/pdfs/en-ca/detrol-la-patient-information-english.pdf.

Provide your doctor with a complete list of all your medications, including prescriptions, over-the-counter (OTC) drugs, vitamins, and herbal supplements. Detrol LA may interact with the following:

• CYP3A4 and CYP2D6 Inhibitors: Detrol LA is metabolized in the liver mainly by enzymes CYP2D6 and, to a lesser extent, CYP3A4. Taking Detrol LA with drugs that inhibit these enzymes can significantly increase its level in your body, raising the risk of side effects. This includes medications such as:
o Certain antifungals: ketoconazole, itraconazole.
o Certain antibiotics: erythromycin, clarithromycin.
o Certain antidepressants: fluoxetine, paroxetine.
o HIV medications: Ritonavir.
• Drugs that Prolong the QT Interval: Tolterodine has been linked to a risk of QT prolongation, which affects the heart's electrical rhythm. Combining it with other medications that also extend the QT interval can increase this risk. This includes certain:
o Antiarrhythmic medications: Amiodarone, quinidine, sotalol, and procainamide.
o Antipsychotics: Thioridazine, ziprasidone.
o Antibiotics: Azithromycin.
• Other Anticholinergic Drugs: Since Detrol LA itself is an anticholinergic, taking it with other medications that have similar effects can cause an additive increase in side effects such as dry mouth, constipation, dry eyes, and difficulty urinating. This includes medications used for:
o Asthma, such as ipratropium.
o Irritable bowel syndrome.
o Motion sickness.
o Parkinson's disease.
• Opioids and Sedatives: Using Detrol LA with opioids or other sedating drugs can raise the risk of drowsiness, dizziness, and constipation.

Pregnancy and Breastfeeding:

Due to uncertainties, if you are pregnant or trying to become pregnant, Detrol LA is generally not recommended. It is also uncertain whether the medicine passes into breast milk or could affect the baby. Therefore, it is best to talk to your doctor about finding the safest way to manage your overactive bladder while pregnant or breastfeeding.

Use in Children:

Detrol LA is generally not used for children because clinical studies have shown it is not an effective treatment for overactive bladder in pediatric patients. Therefore, its use is restricted to adults. If a child shows signs of an overactive bladder, it is essential to consult a pediatrician or pediatric urologist to explore other, more suitable treatment options.

Frequently Asked Questions about Detrol LA at Canada Pharmacy Online:

Why is Detrol LA more affordable in Canada than in the United States?

Prescription drug prices, including Detrol LA, are generally lower in Canada than in the US due to a combination of factors, primarily government price regulations, differing market dynamics, and other economic considerations. In Canada, provincial and federal governments negotiate drug prices with pharmaceutical companies, which often results in lower costs compared to the U.S., where market forces play a more significant role.
