Frequently asked questions
How does lansoprazole work?
Lansoprazole is a proton-pump inhibitor. It reduces the amount of acid the stomach produces, which relieves acid reflux and heartburn and allows the food pipe and stomach lining to recover.
Why is a consultation required for lansoprazole?
Lansoprazole is a prescription-only medicine, so it can only be supplied after a GPhC-registered pharmacist has reviewed your consultation questionnaire and confirmed it is clinically suitable for you. If it is not appropriate, you receive a full refund.
How fast does lansoprazole work?
A PPI is not instant relief. Many people notice an improvement within the first few days, with the full effect building over several days of once-daily use.
When should I take lansoprazole?
It is usually taken once a day, before food — typically about 30 minutes before breakfast. The pharmacist will confirm the right strength and timing for you during the consultation.
What are the common side effects of lansoprazole?
Most people tolerate it well. Possible effects include headache, nausea, diarrhoea, constipation, abdominal pain or wind. Full side-effect information is in the Patient Information Leaflet, which should be read before starting the medicine.
Can I take lansoprazole long term?
Long-term PPI use can affect vitamin B12, magnesium and calcium levels and may need monitoring. Do not extend treatment on your own — discuss continued use with the pharmacist or your GP.
