Magnesii Citrici Parma (Magnesium Citrate)

Magnesium citrate is a mineral supplement that supports electrolyte balance and intestinal function.

• Magnesium deficiency: helps restore normal magnesium stores and reduces related symptoms.
• Hypomagnesemia: provides bioavailable magnesium to correct low serum levels.
• Constipation: increases intestinal water content, facilitating softer stools and regular bowel movements.

• Magnesium citrate dissociates in the gastrointestinal tract to release magnesium ions, which are readily absorbed via active transport and passive diffusion. The increased magnesium concentration enhances enzymatic reactions, stabilizes cellular membranes, and draws water into the intestinal lumen, promoting osmotic laxation and supporting neuromuscular function.

Magnesium citrate may cause adverse reactions, most of which are mild and transient.

Common Side Effects

• Abdominal cramping: mild to moderate discomfort in the stomach area.
• Diarrhea: loose stools occurring after ingestion.
• Nausea: feeling of queasiness or urge to vomit.
• Flatulence: excess gas production.
• Stomach upset: general gastrointestinal discomfort.
• Increased urination: more frequent need to void.

Serious or Rare Side Effects

• Hypermagnesemia: elevated blood magnesium that can affect heart rhythm.
• Severe electrolyte imbalance: abnormal levels of other minerals.
• Allergic reaction: rash, itching, swelling, or difficulty breathing.
• Severe abdominal pain: intense, persistent pain requiring medical attention.
• Cardiac arrhythmia: irregular heartbeat linked to high magnesium levels.
• Anaphylaxis: rare, life‑threatening hypersensitivity response.

When using magnesium citrate, consider the following safety measures.

• Renal function assessment: evaluate kidney health before initiating therapy.
• Serum magnesium monitoring: check levels periodically, especially in high‑risk patients.
• Bowel obstruction caution: avoid use if a mechanical blockage is present.
• Hypersensitivity avoidance: discontinue if allergic signs appear.
• Elderly dose adjustment: start with lower doses in older adults.
• Store at room temperature: keep in the original container, protect from moisture and direct sunlight.

Magnesium citrate can affect the absorption or activity of several medicines.

Major Interactions (Avoid)

• Tetracycline antibiotics: magnesium chelates reduce antibiotic absorption.
• Fluoroquinolone antibiotics: concurrent use lowers fluoroquinolone bioavailability.
• Bisphosphonates: magnesium interferes with oral bisphosphonate uptake.
• Iron supplements: concurrent ingestion decreases iron absorption.
• Calcium supplements: combined use may cause excess mineral load.

Moderate Interactions (Monitor Closely)

• Antihypertensive agents: magnesium may enhance blood‑pressure‑lowering effects.
• Loop or thiazide diuretics: increased magnesium loss may require dose adjustment.
• Proton‑pump inhibitors: may alter magnesium absorption over long term.
• ACE inhibitors: monitor for additive effects on serum electrolytes.
