What is Lansoprazole Used For?
Lansoprazole belongs to a group of medicines known as proton pump inhibitors. It is used to treat gastro-oesophageal reflux disease, a condition where your stomach produces too much acid. The acid travels from your stomach to your food pipe causing irritation and a burning sensation. It can also be used to treat indigestion and heartburn, caused by excess stomach acid. Lansoprazole can reduce the symptoms associated with these conditions, such as:
- A burning sensation in chest and throat
- A sour unpleasant taste at the back of your throat
- Bad breath
- Recurring hiccups and burping
- Bloating
How Does Lansoprazole Work?
Proton pumps in the stomach are responsible for producing stomach acid. Lansoprazole works to reduce the amount of acid produced, which helps to relieve symptoms caused by excess acid production. It also allows your food pipe to heal, if it has been damaged by acid that has travelled from the stomach upwards.
When to Take Lansoprazole
You should take one capsule with water once daily around half an hour before breakfast because food stops some lansoprazole getting into your system.
How Long Does Lansoprazole Take to Work?
Lansoprazole taken to treat acid reflux usually provides relief almost straight away. It may take a few days for the full effect of lansoprazole to be seen. If you do not experience any relief from symptoms after the first week, you should contact your doctor who may wish to carry out tests or prescribe an alternative treatment.
How Long Does Lansoprazole Stay in Your System?
The timeframe is dependent on your metabolism and overall health, as well as the medicine’s half-life.
Can You Take Lansoprazole at Night?
Although this acid reflux medicine can be taken at night, it is recommended to take your dose of lansoprazole in the morning because food can slow down the process of lansoprazole getting into your system.
Does Lansoprazole Cause Weight Gain?
Weight gain is not typically a direct side effect, however indirect factors such as relief from symptoms like heartburn, acid reflux and indigestion may lead to an increase in your appetite which could increase your calorie intake. Additionally, dietary or lifestyle changes can occur when taking proton pump inhibitors (PPIs) which may lead to weight gain.
Can Lansoprazole Cause Bloating?
A gastrointestinal reaction can possibly cause bloating, although not everyone will experience this. Lansoprazole works to suppress stomach acid which can alter the natural gut microbiota leading to bloating. The rate at which your stomach empties can also decline, making you feel full and bloated.
Lansoprazole Side Effects Long Term
If you take a proton pump inhibitor like Lansoprazole, it may slightly increase your risk of fracture in the hip, wrist or spine, particularly when taken over a period of more than one year. Your doctor will likely monitor you and it’s important that you report any new or unusual symptoms straightaway.
The levels of magnesium in your body can also decline if taking lansoprazole for longer than 3 months. This can cause dizziness, fatigue, twitching and increase your heart rate.
What Not To Take with Lansoprazole
Lansoprazole and Alcohol
There is no interaction between alcohol and lansoprazole itself. However, alcohol increases the amount of acid produced by the stomach. Our clinical team recommends avoiding alcohol when experiencing acid reflux to fully benefit from treatment.
Lansoprazole Alternatives
Lansoprazole vs Omeprazole
- Both proton pump inhibitors (PPIs) which effectively reduce stomach acid production
- Omeprazole is available in capsule form, while lansoprazole is available as either capsules or orodispersible tablets, which may be preferable for people who cannot swallow tablets
- Both medicines cause similar side effects
- Preference may be based on your response to one medication over the other
Preventions
You may be able to stop or reduce symptoms of heartburn by making small lifestyle adjustments, such as:
- Eating smaller meals more frequently
- Losing weight if you’re overweight
- Do regular relaxation techniques
- Avoid food or drink that triggers symptom
- Avoid eating 3 or 4 hours before bed
- Avoid wearing tight clothes around your waist
- Quit smoking
- Reduce alcohol intake
- Speak to your doctor first before you stop taking any prescribed medicine

- You have a liver problem – You may need a dose adjustment

- You have had symptoms for 3 weeks
- You are experiencing pain or difficulty trying to swallow
- Your stools are black or blood stained

Lansoprazole Interactions
Can I take lansoprazole with other medications?
Lansoprazole is safe to take with most medication. If you are taking the following medication, you should consult your doctor, as you may need to be monitored:
- Atazanavir, ledipasvir, nelfinavir, rilpivirine, saquinavir, sofosbuvir, tipranavir, velpatasvir or voxilaprevir, which are antivirals used in the treatment of HIV and hepatitis
- Bosutinib, ceritinib, dasatinib, erlotinib, gefitinib or pazopanib, used to treat certain cancers
- Clopidogrel, dipyridamole or digoxin, used to treat heart conditions
- Clobazam or phenytoin, used to treat epilepsy
- Warfarin to treat blood clots
- Citalopram, escitalopram, fluvoxamine or St John’s wort, used in the treatment of depression

- Sucralfate used to treat ulcers
- Tacrolimus, used in transplants

Lansoprazole and Pregnancy/Breastfeeding
Lansoprazole should be avoided in pregnancy since there is little information about its use during pregnancy. You should visit your doctor if you discover you are pregnant whilst taking lansoprazole, discontinue treatment and seek an alternative. There are similar treatments which are suitable for those that are pregnant. Sometimes symptoms can be treated without taking medicine and instead making lifestyle changes such as eating smaller meals more often and avoiding trigger foods. You should also try to sit up straight whilst eating because this helps take the pressure off your stomach.
It may be okay to take lansoprazole while you’re breastfeeding, but only if your doctor or health visitor says your baby is healthy.
The amount of lansoprazole which passes into breast milk is not currently known, but it’s likely to be a very small amount and your baby will not absorb a lot into their body from the breast milk.

Frequently Asked Questions
We have an experienced clinical team who will only provide a short-term treatment for acid reflux. There are several reasons for this:
- Long term use of lansoprazole can increase the likelihood of bone fractures. If your doctor has prescribed you lansoprazole to take over a long period of time, you will need to be monitored to ensure that you have adequate levels of vitamin D, to minimise the chances of bone injury.
- The symptoms of acid reflux are similar in nature to stomach cancer. Lansoprazole can mask these symptoms, which could potentially be hazardous to your health. If you are experiencing symptoms like acid reflux for more than 3 weeks, you should see your doctor as soon as possible.
- Taking lansoprazole for longer than 3 months can reduce the amount of magnesium in your body. Magnesium is required in order to maintain healthy glucose levels, heartbeat and muscle and nerve function. Low magnesium can negatively affect your health, leaving you feeling dizzy, tired, twitching and increasing your heart rate.
If your doctor has authorised long term use of lansoprazole, and you wish to purchase more than a one-month supply, you can call us to speak to one of our pharmacists.
No, this medicine is not available to buy over the counter. You can only get lansoprazole on prescription.
All three treatments are proton pump inhibitors (PPIs) and work in a similar way. If you are looking for a lansoprazole alternative the best treatment will be largely down to individual needs and preference, based on the condition being treated, your overall health, tolerance and cost. All three options are generic medications meaning they have the same active ingredient as the brand-name medicines and work in the same way. Our experienced clinicals will assess and advise on the best course of treatment for you.
It is best to take lansoprazole before food to ensure it is fully absorbed by your body. Food can interrupt this process.
You can take Gaviscon and lansoprazole together, however it’s best to space out the timing to avoid interference. Lansoprazole should be taken at least 30 minutes before a meal, and if needed, Gaviscon may be taken after meals or at bedtime.
Please note: You should always seek advice from a pharmacist or your doctor before combining medications.
This is typically 1 tablet a day, but the dose depends on your condition. You should always follow the advice of your doctor or pharmacist and read the patient information leaflet.
