Calac 300 mg Tablet

Calac 300 mg tablet by Opsonin Pharma Limited is a calcium supplement that contains Calcium Lactate. In Bangladesh, it is mainly used to help prevent or treat low calcium intake or calcium deficiency when dietary calcium is not enough.

Calcium Lactate works by supplying calcium, an essential mineral needed for bones, teeth, muscles, nerves, and normal body functions. A key caution is that people with kidney disease, kidney stones, high blood calcium, or high vitamin D levels should use it only after medical advice.

• Prevention and treatment of calcium deficiency when dietary intake is inadequate.
• Calcium supplementation during periods of increased requirement, such as pregnancy, breastfeeding, adolescence, or older age, when advised by a healthcare professional.
• Adjunct supplementation in osteoporosis or osteopenia as part of a broader management plan.
• Supportive calcium replacement in conditions associated with low calcium levels, as directed by a doctor.

The dose of Calcium Lactate depends on the person’s age, diet, medical condition, pregnancy or breastfeeding status, and the amount of elemental calcium in each tablet. Adults are commonly advised to take calcium supplements with food and, if more than one tablet is needed, in divided doses for better absorption and stomach tolerance. Follow the dose on the prescription or product label, and do not exceed the recommended daily calcium intake unless specifically instructed by a doctor.

• Common: constipation, nausea, stomach discomfort, gas, bloating, or dry mouth.
• Less common: increased thirst or increased urination, especially with excessive intake.
• Serious: high blood calcium, kidney stones, irregular heartbeat, confusion, severe weakness, or persistent vomiting; seek medical help if these occur.
• Allergic reactions are rare but may include rash, itching, swelling, dizziness, or breathing difficulty.

Use Calcium Lactate cautiously if you have kidney disease, a history of kidney stones, high blood calcium, high vitamin D levels, sarcoidosis, parathyroid disorders, or if you are taking other calcium or vitamin D supplements. Avoid long-term high-dose use unless monitored, because excessive calcium can cause hypercalcaemia or kidney problems. Use under the guidance of a registered doctor or pharmacist, especially in children, older adults, pregnant or breastfeeding women, and people with chronic illness.

• Tetracycline and quinolone antibiotics: calcium can reduce absorption; separate dosing as advised by a healthcare professional.
• Levothyroxine: calcium can reduce absorption; take at a different time as advised.
• Bisphosphonates such as alendronate: calcium can interfere with absorption; separate dosing carefully.
• Iron, zinc, and some other mineral supplements: absorption may be reduced when taken together.
• Thiazide diuretics: may increase the risk of high blood calcium.
• Digoxin or other cardiac glycosides: high calcium levels may increase the risk of heart rhythm problems.
• High-dose vitamin D: may increase calcium absorption and the risk of hypercalcaemia.
• Foods high in oxalates or phytates, such as spinach, bran, and some cereals, may reduce calcium absorption if taken at the same time.

• Known allergy or hypersensitivity to calcium lactate or any tablet ingredient.
• High blood calcium levels (hypercalcaemia).
• High urine calcium levels with risk of stones, unless specifically managed by a doctor.
• Severe kidney impairment or kidney stones where calcium supplementation is not advised.
• Conditions causing excess vitamin D or calcium, unless under specialist supervision.

Calcium is an essential nutrient during pregnancy and breastfeeding, and supplementation may be appropriate when dietary intake is insufficient. However, the total daily calcium intake from diet, supplements, and prenatal products should be considered to avoid excessive intake. Pregnant or breastfeeding women should use Calcium Lactate at the dose recommended by their doctor or pharmacist.
