Special Precautions

• Extreme caution is necessary when starting therapy in patients over 50 years old or those with existing heart conditions like coronary heart disease, as over-treatment may precipitate heart problems.
• Patients with diabetes should have their blood sugar levels carefully monitored, as treatment may require adjustments to anti-diabetic medications.
• Those with a history of weak bones (osteoporosis) should avoid supra-physiological levels of the active ingredient.

Is it safe to take it with other medications?

The drug can increase the effects of blood thinners, potentially increasing the risk of bleeding. Medicines containing iron, calcium salts, or aluminum (like antacids) can significantly reduce absorption and must be taken hours apart. Certain medications for depression or seizure disorders may also require dosage adjustments.

How should I store it?

Store between 15-30°C. Keep the tablets protected from moisture and direct light to maintain the drug’s effectiveness.
