To ensure Fortamet works effectively and safely, it’s crucial to follow your doctor’s instructions precisely. Fortamet is an extended-release tablet, meaning it should be taken differently from standard tablets.

• Take with Food: Always take Fortamet with your evening meal. Taking it with food helps reduce stomach upset, which is a common side effect, and aids in its slow absorption.
• Swallow Whole: Do not crush, chew, or break the tablet. It must be swallowed whole to allow the extended-release mechanism to work correctly. Breaking the tablet can cause the medication to be released too quickly, leading to higher drug levels and potential side effects.
• Consistent Schedule: Try to take your dose at the same time each day to maintain steady blood sugar control.
• Missed Dose: If you miss a dose, take it as soon as you remember, unless it’s almost time for your next scheduled dose. In that case, skip the missed dose and continue with your regular schedule. Do not take two doses at once.

Fortamet works through several key mechanisms to lower blood glucose levels in people with type 2 diabetes. Its primary actions are:

• Decreases Glucose Production in the Liver: Fortamet reduces the amount of glucose (sugar) produced by the liver. The liver naturally produces glucose, and in type 2 diabetes, this production can be too high.
• Increases Insulin Sensitivity: It helps the body’s cells respond better to insulin. Insulin is a hormone that moves sugar from the blood into cells for energy. When cells become more sensitive to insulin, they can absorb more glucose from the bloodstream.
• Reduces Glucose Absorption: Fortamet also slightly decreases the absorption of glucose from the food you eat in your intestines.

By working in these ways, Fortamet effectively lowers blood sugar levels, helping to keep them within a healthy range.

While Fortamet is generally well-tolerated, some side effects can occur. Most are mild and often lessen over time as your body adjusts to the medication.

• Gastrointestinal Issues: The most common side effects are related to the digestive system, including:
  • Diarrhea
  • Nausea
  • Vomiting
  • Stomach upset or discomfort
  • Gas
  • Metallic taste in the mouth These often improve by taking the medication with food and by slowly increasing the dose as directed by your doctor.
• Low Blood Sugar (Hypoglycemia): While Fortamet alone rarely causes very low blood sugar, the risk increases if it’s used with other diabetes medications like insulin or sulfonylureas, or if meals are skipped.
• Lactic Acidosis: This is a very rare but serious side effect. Symptoms include unusual muscle pain, trouble breathing, stomach pain, dizziness, and feeling cold. Seek immediate medical attention if you experience these.

Report any persistent or severe side effects to your doctor.

Before starting Fortamet, and during treatment, several important warnings and precautions should be considered to ensure safe use.

• Kidney Function: Fortamet should not be used in individuals with severe kidney problems, as this increases the risk of lactic acidosis. Your doctor will likely check your kidney function before and during treatment.
• Liver Disease: Patients with liver disease should use Fortamet with caution or avoid it, as impaired liver function can also increase the risk of lactic acidosis.
• Heart Failure: Use in severe heart failure is generally not recommended.
• Alcohol Consumption: Limit alcohol intake while on Fortamet, as excessive alcohol use can increase the risk of lactic acidosis.
• Surgery or Medical Procedures: If you are having surgery or any medical imaging procedure involving injectable contrast dye, you may need to temporarily stop Fortamet. Your doctor will provide specific instructions.
• Vitamin B12 Deficiency: Long-term use of metformin, including Fortamet, can sometimes lead to a decrease in vitamin B12 levels. Regular monitoring may be advised.
• Pregnancy and Breastfeeding: Discuss with your doctor if you are pregnant, planning to become pregnant, or breastfeeding.

• Corticosteroids: These medications, often used for inflammation, can also raise blood sugar, requiring careful monitoring.
• Certain Blood Pressure Medicines: ACE inhibitors or ARBs, for instance, can sometimes lower blood sugar, leading to a risk of hypoglycemia when combined with Fortamet.
• Contrast Dyes for Imaging: If you need an X-ray or scan that uses an injectable dye, you may need to stop Fortamet for a period before and after the procedure due to a risk of kidney problems.
• Other Diabetes Medications: Combining Fortamet with other drugs for diabetes can increase the risk of low blood sugar (hypoglycemia), especially with insulin or sulfonylureas.

Always provide a complete list of your current medications to your healthcare provider.

The dosage of Fortamet is determined by your doctor based on your individual needs, blood sugar levels, and how well you tolerate the medication. It’s crucial to follow their instructions precisely and never adjust your dose without medical advice.

• Starting Dose: Treatment typically begins with a low dose, for example, 500 mg once daily with the evening meal.
• Gradual Increase: Your doctor may slowly increase the dose over several weeks to minimize gastrointestinal side effects and find the most effective dose for you. The maximum recommended daily dose for Fortamet is generally 2500 mg.
• Monitoring: Your blood sugar levels and A1C will be regularly monitored to see how well the medication is working. Your doctor may adjust the dosage based on these results.
• Consistent Timing: Always take Fortamet at the same time each day, usually with your evening meal, to maintain steady drug levels and optimal blood sugar control.
• Do Not Split or Crush: As an extended-release tablet, it must be swallowed whole to ensure the medicine is released slowly throughout the day.

Fortamet is a prescription-only medication. This means you cannot obtain it without a valid prescription from a licensed healthcare provider.

• Medical Consultation: A doctor’s visit is necessary to assess if Fortamet is the right treatment for your type 2 diabetes. This consultation will involve a review of your medical history, current health status, and possibly blood tests to check blood sugar levels and kidney function.
• Diagnosis and Monitoring: Because type 2 diabetes requires careful management and Fortamet has specific contraindications and potential side effects (like lactic acidosis), a doctor needs to oversee its use. They will monitor your progress and adjust the dosage as needed.
• Risk Assessment: The doctor will evaluate potential risks, such as kidney impairment or interactions with other medications you are taking, before prescribing Fortamet.
• Renewals: Prescriptions for Fortamet often require periodic renewal, which typically involves follow-up appointments with your doctor to ensure the medication is still appropriate and effective for your condition.
