PEPLOC is a prescription medicine that lowers excess stomach acid. It contains pantoprazole (a proton pump inhibitor, or PPI) . Doctors prescribe PEPLOC in adults for conditions such as ulcers, reflux disease and certain rare disorders that cause very high acid output. The tablets are swallowed whole, usually once daily before a meal, and it can take several days for symptoms to improve.
What it is and what it is used for
PEPLOC contains pantoprazole, a proton pump inhibitor that reduces the amount of acid your stomach produces. Too much acid can irritate or damage the lining of the stomach and oesophagus (food pipe), causing symptoms such as heartburn and pain on swallowing.
Indications
- PEPLOC 40 mg is used for:
- Treatment of duodenal ulcers and gastric (stomach) ulcers.
- Treatment of heartburn.
- Treatment of Zollinger–Ellison Syndrome (a rare disorder causing tumours in the pancreas/duodenum and very high acid levels, often with ulcers).
- PEPLOC 20 mg is used for:
- Treatment of symptoms of heartburn, pain during swallowing, and for healing of mild gastro-oesophageal reflux disease (GORD).
- Long-term management and prevention of recurrence of GORD.
Note: Use is limited to the indications above and as directed by your doctor.
How it works
Your stomach makes acid using tiny “pumps” in the stomach lining. Pantoprazole switches off many of these pumps, so the stomach produces less acid. Lower acid levels reduce irritation and allow ulcers and inflammation to heal. Because the body needs time to adjust, symptom relief is not immediate and may take several days.
Who should NOT use this medicine
Do not take PEPLOC if any of the following apply:
- You are allergic (hypersensitive) to pantoprazole or any of the ingredients in PEPLOC.
- Your liver function is impaired.
- You are taking atazanavir (used to treat HIV).
- You are a child (safety and efficacy have not been established).
If you are unsure about any of the above, speak to your doctor or pharmacist before taking PEPLOC.
Warnings and precautions (Read before use)
Tell your doctor before you start PEPLOC, and during treatment, if any of these apply:
- Kidney problems: If you have impaired kidney function, or if you notice reduced urination or blood in your urine, inform your doctor promptly.
- Blood-thinning treatment: If you take warfarin (or similar), your doctor may monitor your clotting more closely.
- Liver disease: Inform your doctor if you have liver problems (in addition to the “do not use” if liver function is impaired).
- Low magnesium: Tell your doctor if you have low magnesium or are prone to it. With use longer than three months, PPIs can lower magnesium. Symptoms include fatigue, muscle spasms, disorientation, convulsions, dizziness or rapid heartbeat. Low magnesium can also lead to low potassium or calcium. Your doctor may order blood tests to monitor this.
- History of stomach malignancy: If you are being treated for, or have a history of stomach-area malignancy, tell your doctor.
- Vitamin B12 deficiency: Inform your doctor if you have a history of vitamin B12 deficiency.
- Persistent diarrhoea: If you develop diarrhoea that does not improve, contact your health care professional as soon as possible.
- Long-term or high-dose use; age over 50: Long-term use (more than 1 year) or higher doses may be associated with low magnesium and an increased risk of bone fractures in the hip, wrist or spine. If you already had a fracture related to low magnesium, tell your doctor.
- HIV protease inhibitors: If you are taking atazanavir or other HIV protease inhibitors, ask your doctor for specific advice; do not use with atazanavir.
- Skin rash in sun-exposed areas: If you develop a rash on skin exposed to sunlight, inform your doctor; you may need to stop PEPLOC. Mention any other symptoms such as joint pain.
- Regular surveillance: If you take pantoprazole long-term (over a year), your doctor will likely review you regularly. Report any new or unusual symptoms.
- Sodium content: PEPLOC contains sodium; your doctor will consider this if you are on a sodium-restricted diet.
Driving and using machines
PEPLOC may cause blurred vision or dizziness. Do not drive or operate machinery until you know how PEPLOC affects you.
Pregnancy, planning pregnancy, and breastfeeding
Do not use PEPLOC if you are pregnant or breastfeeding. Safety in pregnancy and breastfeeding has not been established. If you are pregnant, think you may be pregnant, are planning a pregnancy, or are breastfeeding, speak to your doctor or pharmacist before use.
Interactions
Always tell your health care provider about all medicines you use (including complementary or traditional remedies). The following interactions are mentioned in the source:
- Warfarin (blood thinner): PEPLOC may alter its effect; your health care provider may monitor clotting.
- Atazanavir (anti-HIV): PEPLOC may reduce atazanavir levels. Do not use PEPLOC at the same time as atazanavir.
- Ketoconazole (antifungal): PEPLOC may reduce absorption of certain antifungals such as ketoconazole.
- Methotrexate (high doses): PEPLOC may increase methotrexate levels and lead to toxicity, particularly with high-dose methotrexate used in some cancers.
- Fluvoxamine (for depression/psychiatric conditions): Your doctor may reduce the fluvoxamine dose.
- St John’s wort (Hypericum perforatum): Mentioned in the source (used for mild depression).
Note: Follow your doctor’s advice on spacing or adjusting medicines if required.
How to take (Step-by-step)

- When to take: Take the recommended once-daily dose before a meal, preferably in the morning.
- How to take: Swallow the tablet whole with water. Do not crush, break, or chew the tablet.
- Onset: It may take several days for symptoms to improve. Antacids may be used with PEPLOC to help relieve symptoms, unless your doctor has told you not to.
- Do not stop early: Take PEPLOC for the full duration prescribed, even if you start to feel better; stopping too soon could worsen the condition.
