Campral at CanadaPharmacyOnline.com

Campral (acamprosate), a brand-name medication, is sourced from different manufacturers depending on the region. In Canada, it is marketed by Mylan, a subsidiary of Viatris. In other parts of the world, such as Turkey, Campral is manufactured and marketed by Merck.

Generic acamprosate is currently unavailable (at this pharmacy).

Dosage

Campral (acamprosate) is an oral medication that is commonly available as:
• Tablets: 333 mg, delayed-release

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

Usage

Campral (acamprosate) is a prescription medication used to help people with alcohol dependence maintain abstinence. It is indicated for use in patients who are already abstinent at the initiation of treatment. Campral is most effective when used as part of a comprehensive management program that includes psychosocial support and counselling.

Mechanism of Action
The exact way Campral works is not fully understood. However, it is believed to act on the central nervous system to help restore the normal balance between the brain's excitatory and inhibitory systems, which is often altered by chronic alcohol use.

Specifically, it is thought to modulate glutamatergic neurotransmission (the brain's primary excitatory system) and may also affect the inhibitory GABAergic system. By helping to re-establish this balance, acamprosate is thought to reduce the unpleasant symptoms of protracted abstinence, such as anxiety, restlessness, and insomnia, which can trigger a return to drinking.

Campral does not treat acute alcohol withdrawal symptoms. It should only be started after withdrawal is complete.

Take Campral exactly as your doctor prescribes, 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 Campral, it is essential to discuss all possible side effects, risks, and interactions with your doctor or pharmacist.

Common Side Effects - The following are some common side effects of Campral; other side effects may also occur. Contact your doctor promptly if any side effects persist, worsen, or concern you, or if you experience any other concerning symptoms.
• Abdominal pain
• Changes in sexual desire or ability
• Constipation
• Diarrhea (most common)
• Dizziness

Serious Side Effects - These are rare but potentially severe side effects. Seek immediate medical attention or call emergency services if you experience any of the following:

• Kidney problems: Changes in the amount of urine, swelling, or feeling tired.
• Mental or mood changes: Severe depression, anxiety, or thoughts of self-harm or suicide.

Contraindications

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

Campral should not be used if:
• You are allergic to acamprosate calcium or any other ingredient in Campral.
• You have severe renal impairment (creatinine clearance less than or equal to 30 mL/min).

Tell your doctor about all of your medical conditions, past and present, before starting Campral. This is crucial because certain conditions affect whether Campral is right for you. These conditions may include, but are not limited to:
• A history of depression or suicidal thoughts
• Kidney disease or impaired kidney function
• Severe liver disease (Child-Pugh Class C)

Drug Interactions

Before taking Campral, 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 Details for: CAMPRAL - Drug and Health Product Register at https://hpr-rps.hres.ca/details.php?drugproductid=110 and the labeling information at https://www.accessdata.fda.gov/drugsatfda_docs/label/2012/021431s015lbl.pdf.

Provide your doctor with a complete list of all your medications, including:
• Prescription drugs
• Over-the-counter (OTC) medications
• Vitamins and herbal supplements
• Herbal teas and recreational drugs
• Any significant changes to your diet

This information is crucial because it helps your doctor prevent potential drug interactions and ensure the treatment is right for you.

How Campral Works and What to Know
• Caution with Kidney-Affecting Drugs: Because your kidneys clear Campral from your body, you should be careful with any medications that affect kidney function or are also cleared by the kidneys. These could potentially change how effective Campral is.
• Low Risk of General Interactions: Campral is not metabolized by the liver, which means it has a low chance of interacting with many other drugs.
• No Adverse Reaction to Alcohol: Unlike some other medications for alcohol dependence, Campral does not cause a physical reaction if you consume alcohol while taking it.
• Use with Other Alcohol Medications: While some medications for alcohol dependence, like naltrexone, can be used with Campral, always follow your doctor's guidance to ensure your treatment is safe and effective.

Pregnancy and Breastfeeding

The safety of Campral during pregnancy has not been established. Animal studies have shown some adverse effects. Therefore, this medication should be used during pregnancy only if the potential benefit to the mother clearly justifies the potential risk to the fetus. If you are pregnant or become pregnant while taking Campral, you should tell your doctor immediately.

It is unknown whether acamprosate is excreted in human milk. However, due to the potential for severe adverse reactions in a nursing infant, Campral is generally not recommended for use by nursing women. You should discuss with your doctor whether to discontinue breastfeeding or to discontinue the drug, based on your health needs.

Use in the Elderly

Studies on acamprosate did not include enough patients aged 65 and over to determine if they respond differently from younger patients. Since elderly patients are more likely to have reduced kidney function, doctors should exercise caution when selecting a dose. Regular monitoring of kidney function may be necessary in this population.

Use in Children

The safety and effectiveness of Campral have not been established in children and adolescents. Therefore, it is not approved for use in patients under 18 years of age.
