Overview

Dyna Tetracycline 250mg Capsule is a prescription-only medicine (POM) that contains Tetracycline hydrochloride 250mg. It is supplied as a capsule and is dispensed in Malaysia only against a valid prescription issued by a registered doctor.

Under Malaysian rules for prescription medicines, this page carries product, safety and handling information only. Your doctor or pharmacist will explain whether this medicine is suitable for you, the dose you should take, and how long you should take it.

On DoctorOnCall, Dyna Tetracycline 250mg Capsule is reviewed by a licensed doctor through an online consultation and dispensed by a registered pharmacist before delivery. Always follow the instructions on your prescription label and the package insert supplied with the product, and do not share this medicine with anyone else.

Directions for Use

Take Dyna Tetracycline 250mg Capsule on an empty stomach, at least 1 hour before or 2 hours after meals or dairy products, with a full glass of water. Do not lie down immediately after taking this medicine, as it can irritate the oesophagus. Avoid taking it with milk, other dairy products, calcium, iron, antacids, or mineral supplements, as these significantly reduce absorption.

Dosage

The dose of Dyna Tetracycline 250mg Capsule is determined by your doctor based on the type and severity of the infection or acne being treated, usually taken several times daily for a set course. Complete the full course exactly as prescribed, even if your symptoms improve earlier.

Storage Instructions

Store below 30°C in a dry place, away from direct sunlight and out of reach of children.

Side Effects

  • Nausea or vomiting
  • Diarrhoea

  • Skin rash or itching
  • Discoloration of teeth (especially in children)
  • Dizziness

Contraindications

  • Known hypersensitivity to tetracycline or other tetracycline-class antibiotics

  • Pregnant women, due to the risk of impaired bone growth in the developing fetus and tooth discolouration
  • Significant kidney impairment (dose adjustment or avoidance needed)

Drug / Food Interactions

  • Dairy products, calcium, iron, antacids, and mineral supplements chelate with tetracycline and significantly reduce its absorption – separate dosing by at least 1-2 hours
  • May reduce the effectiveness of oral contraceptives – discuss additional contraceptive precautions with your doctor
  • Warfarin’s blood-thinning effect (INR) may be enhanced, requiring closer monitoring
  • Concurrent use with retinoids (e.g. isotretinoin) increases the risk of raised pressure in the brain and should be avoided

Quick Tips

  • Take on an empty stomach, well separated from dairy products, calcium, iron, or antacids
  • Use sun protection – avoid excessive sun exposure and use sunscreen, as this medicine increases photosensitivity
  • Do not lie down for at least 10 minutes after taking a dose
