Zolepant is a generic brand of Protium. Zolepant is used to treat certain conditions caused by too much acid being produced in the stomach.
How does Zolepant work?
- Acid is produced naturally in your stomach to help you digest food and to kill bacteria. This acid is irritant so your body produces a natural mucous barrier which protects the lining of your stomach. In some people this barrier may have broken down allowing the acid to damage the stomach, causing inflammation, ulcers and other conditions. In other people there may be a problem with the muscular band at the top of the stomach that keeps the stomach tightly closed. This may allow the acid to escape and irritate the oesophagus. This is called 'acid reflux' and can cause heartburn and/or oesophagitis.
- Proton pump inhibitors such as Zolepant stop cells in the lining of the stomach from producing too much acid.
How to take Zolepant
- Before starting this treatment, read the manufacturer's printed information leaflet from inside the pack. Take Zolepant exactly as your doctor has told you. Try to take Zolepant at the same time each day to avoid missing any doses. The usual dose is once a day in the morning. However, if you are taking Zolepant for Helicobacter pylori eradication, you will be asked to take two doses a day - one in the morning and one in the evening. Swallow Zolepant tablets whole. Do not chew or crush the tablets.
- Take each dose an hour before a meal. If you forget to take a dose, take it as soon as you remember unless it is nearly time for your next dose, in which case leave out the missed dose. Do not take two doses together to make up for a forgotten dose.
What is Zolepant used for?

How can Zolepant affect other medicines?
You should tell your doctor or pharmacist what medicines you are already taking, including those bought without a prescription and herbal medicines, before you start treatment with this medicine. Similarly, check with your doctor or pharmacist before taking any new medicines while taking this one, to make sure that the combination is safe.
Zolepant should not be taken by people taking the anti-HIV medicines atazanavir or rilpivirine. This is because Zolepant reduces the absorption of these medicines from the gut and could make them less effective at treating HIV infection.
Proton pump inhibitors such as Zolepant are not recommended for people taking the anti-HIV medicines raltegravir or saquinavir, because they may increase the blood level of these medicines and may therefore increase the risk of their side effects.
Due to its effect on the acidity in the stomach, Zolepant may reduce the absorption of the following medicines from the stomach, which could make them less effective:
This medicine may enhance the anti-blood-clotting effect of anticoagulant medicines such as warfarin. As this could increase the risk of bleeding, if you are taking warfarin your doctor may want to perform extra monitoring of your blood clotting time (INR) when you start and stop treatment with this medicine, or if you take it irregularly.
There may be a greater chance of the level of magnesium in your blood falling too low if you are taking this medicine with digoxin, diuretics (such as bendroflumethiazide or furosemide) or other medicines that can lower blood magnesium levels. If you are taking one of these your doctor may want you to have a blood test to check your magnesium levels before you start taking Zolepant and then regularly during treatment.
