Meropenem is a very strong antibiotic given through injection (drip or IV) that works by killing a wide range of bacteria. It belongs to a powerful group of antibiotics called carbapenems, which are usually reserved for serious infections that other antibiotics cannot handle.
Prescription Required
You need a doctor's prescription to buy this drug.
Explore this drug
This drug is NOT taken by mouth — it is given as an injection into your vein (IV) by a doctor or nurse in a hospital. The usual adult dose is 500 mg to 1 g given every 8 hours. For very serious infections like meningitis, the dose may be increased to 2 g every 8 hours. Your doctor will decide the exact dose and how long you need it based on how serious your infection is.
Since this drug is given by healthcare workers in a hospital, missed doses are rare. However, if a dose is missed, it should be given as soon as possible and the regular schedule resumed. Do not double the dose to make up for a missed one.
Important for antibiotics
Always complete the full course even if you feel better. Stopping early can cause the infection to return and become drug-resistant.
This is a hospital-only drug — do not attempt to buy and inject it yourself at home or from roadside medicine sellers. Always complete the full course your doctor prescribes, even if you feel better, to prevent antibiotic resistance which is a serious problem in Nigeria. Do not share this medication or use leftover portions for another person's illness.
Valproic acid (a drug used for epilepsy/convulsions) — Meropenem can seriously reduce its effectiveness, making seizures more likely. Probenecid (used for gout) — can increase the level of Meropenem in your blood and raise the risk of side effects. Always tell your doctor about every drug you are currently taking before starting Meropenem.
Check your specific combination
Is it safe to take Meropenem with your other drugs?
Meropenem should only be used during pregnancy or breastfeeding if your doctor decides the benefit clearly outweighs the risk — always consult your doctor before use.
Store the unopened powder vials at room temperature, below 30°C — avoid direct sunlight and damp areas, which is important in Nigeria's humid climate. Once mixed with water for injection, it should be used within the time your pharmacist specifies (usually within a few hours). Keep away from children at all times.
For information only — not medical advice. Always talk to a doctor or pharmacist before changing your medication.
