Minocycline Crescent Pharma (Minocycline Hydrochloride)

Minocycline is a broad‑spectrum tetracycline that targets bacterial infections of the skin, respiratory and urinary systems.

• Acne vulgaris: reduces inflammatory lesions and bacterial colonisation on the skin.
• Skin and soft tissue infections: eradicates susceptible Gram‑positive and Gram‑negative organisms.
• Respiratory tract infections: treats community‑acquired pneumonia and sinusitis caused by susceptible pathogens.
• Urinary tract infections: eliminates common uropathogens in uncomplicated cases.

• Minocycline inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit, blocking the attachment of amino‑acyl‑tRNA. This prevents elongation of the nascent peptide chain, halting bacterial growth and leading to a bacteriostatic effect against a wide range of susceptible microorganisms.

Adverse reactions may vary in frequency and severity.

Common Side Effects

• Nausea: mild to moderate gastrointestinal upset.
• Photosensitivity: increased skin sensitivity to sunlight.
• Dizziness: transient vertigo or light‑headedness.
• Headache: mild to moderate cephalic pain.

Serious or Rare Side Effects

• Stevens‑Johnson syndrome: severe mucocutaneous reaction requiring immediate medical attention.
• Drug‑induced hepatitis: elevated liver enzymes or jaundice.
• Pseudotumor cerebri: increased intracranial pressure presenting with headache and visual changes.

Before initiating therapy, consider patient‑specific factors and safety measures.

• Pregnancy: consult prescriber; limited safety data are available.
• Renal impairment: dose adjustment may be required in reduced kidney function.
• Hepatic disease: use with caution; monitor liver function tests.
• Concomitant isotretinoin: increased risk of intracranial hypertension; avoid co‑administration.
• Sun exposure: advise protective clothing and sunscreen to mitigate photosensitivity.

Store at ambient temperature: keep in original container, protect from moisture and direct light.

Minocycline may interact with several drug classes, altering efficacy or safety.

Major Interactions (Avoid)

• Aminoglycosides: antagonistic antibacterial effect when combined.
• Oral anticoagulants: potentiation of anticoagulant effect, increasing bleeding risk.
• Antacids containing aluminium or magnesium: reduce minocycline absorption.

Moderate Interactions (Monitor Closely)

• Oral contraceptives: decreased hormonal efficacy, consider alternative contraception.
• Vitamin D supplements: may increase risk of hypercalcemia; monitor serum calcium levels.
