How Dexilant works (mechanism of action)

Your stomach contains tiny “acid pumps” in its lining called proton pumps (mainly H⁺/K⁺-ATPase). Dexilant works by blocking these pumps, so less acid is produced.

By lowering acid levels, Dexilant helps:

• Reduce symptoms such as heartburn and acid reflux
• Allow healing of irritated or damaged tissue in the oesophagus (in appropriate cases)
• Improve control of GORD symptoms, including those that occur later in the day or at night

Dexlansoprazole is formulated for dual delayed release. This can help provide a more sustained acid suppression profile compared with some other single-release PPIs.

Pharmacokinetics (how the body handles the medicine)

Pharmacokinetics describes how the body absorbs, distributes, metabolises, and eliminates a medicine. Dexilant’s performance is influenced by its dual release design.

Absorption and onset

After swallowing, the medication releases in stages, designed to extend its effect through the day. Many people notice symptom improvement within several days, though full benefits may take longer depending on the condition.

Distribution

Once absorbed, dexlansoprazole reaches the stomach lining where proton pumps are present.

Metabolism

Dexlansoprazole is metabolised primarily in the liver. Drug interactions may occur with medicines that affect these pathways (see “Medicine interactions” below).

Elimination

The medicine and its metabolites are cleared from the body mainly via the liver and bile pathways.

Important: Individual responses vary. If symptoms persist or worsen, speak to a pharmacist or prescriber for advice.

What Dexilant is typically used for (indications)

Dexilant is commonly used for acid-related disorders, especially where acid suppression helps relieve symptoms and support healing. In the UK, use may align with approved indications and local clinical practice.

• Gastro-oesophageal reflux disease (GORD) — including heartburn and regurgitation
• Oesophagitis — inflammation of the oesophagus due to acid reflux (where applicable)
• Symptom relief in people with acid reflux symptoms, as advised by healthcare professionals

If you have frequent heartburn (for example, most days), or symptoms returning quickly after stopping treatment, ask a pharmacist or GP about the best long-term approach.

---

Dosing and timing

Typical dosing approach

Dexilant is usually taken once daily. The exact dose depends on the condition being treated and your response. Follow your label directions or clinician instructions.

When to take it

Many people find that PPIs work best when taken at a consistent time each day. Dexilant’s dual release may suit different daily routines, but the key principle is consistency.

• Take Dexilant at the time stated on your package/label.
• If you are unsure whether to take it before or after food, follow the specific instructions given with your product or from your healthcare professional.

How to take the capsule/tablet

Dexilant should be taken as directed on the packaging. Do not crush or chew unless the product information specifically allows it. If you have difficulty swallowing pills, ask your pharmacist for advice.

If you miss a dose

If you miss a dose, take it as soon as you remember, unless it is near the time of your next dose. Do not take a double dose to make up for the missed one.

---

Food interactions (what to know about meals)

Unlike some medicines where timing relative to meals is critical, Dexilant’s dual release can make it more flexible for people who eat at different times. However, it’s still important to follow the label or advice from your healthcare professional.

General guidance

• For best reliability, take it at the same time each day.
• If your prescriber/pharmacist advised a particular approach (e.g., with or without food), follow that advice.

Dietary triggers

Even with PPIs, lifestyle factors can influence reflux. Consider reducing:

• Large late meals
• High-fat foods
• Chocolate, mint, caffeine (for some people)
• Spicy or acidic foods if they trigger symptoms
• Smoking

---

Alcohol and medicine interactions

Alcohol

Alcohol does not typically have a specific direct interaction with dexlansoprazole that makes it unsafe for most people, but alcohol can worsen reflux symptoms by relaxing the valve between the oesophagus and stomach or by irritating the lining.

If you drink alcohol and notice heartburn afterwards, reducing or avoiding alcohol may improve control.

Other medicine interactions

PPIs can affect how some medicines are absorbed or metabolised. Always tell your pharmacist about all medicines you take, including over-the-counter products and supplements.

Medicines where caution may be needed

• Medicines that rely on stomach acidity for absorption (some antifungals and other medicines may be affected)
• Drugs with interactions through liver enzymes (dexlansoprazole is metabolised in the liver; changes in metabolism may occur with other medicines)
• Medicines affecting blood clotting (if you take anticoagulants, ask about monitoring and interaction risk)
• Other acid-suppressing medicines (taking multiple PPIs together is generally not advised unless specifically directed)

Herbal and supplement interactions

Some herbal products can alter liver enzyme activity. If you use St John’s wort or other herbal supplements, discuss them with a pharmacist.

Tip: Keep a written list of your medicines and show it to your pharmacist, especially when starting or stopping any medicines.

Safety profile and side effects

Common side effects

Most people tolerate Dexilant well. As with all medicines, side effects can occur. The likelihood and severity vary between individuals.

• Headache
• Nausea or stomach discomfort
• Diarrhoea or constipation
• Gas (flatulence)
• Dry mouth

Seek medical help urgently if

• You develop signs of an allergic reaction (e.g., swelling of the face/lips, difficulty breathing, severe rash)
• Severe or persistent symptoms occur, particularly if they are new or worsening

Long-term use considerations (PPIs in general)

Long-term PPI therapy is sometimes necessary, but clinicians generally aim for the lowest effective dose for the shortest duration that keeps symptoms controlled. Discuss ongoing need if you’ve been taking a PPI for a long time.

With long-term use of PPIs, potential concerns that may be considered by healthcare professionals include:

• Low magnesium (hypomagnesaemia) — may require monitoring
• Higher risk of certain infections (for example, gut infections) — because acid suppression can change gut environment
• Vitamin and mineral absorption changes in some circumstances

These are not guaranteed effects and do not mean you should stop without advice. If you have concerns, speak to a pharmacist or GP.

Who should take extra care?

• People with a history of liver problems
• Those taking multiple medicines that may interact
• Older adults, especially if taking other medicines or experiencing persistent symptoms
• People with swallowing difficulties, unexplained weight loss, or bleeding symptoms (see “When to seek urgent advice”)

---

Practical use tips for better results

• Be consistent: take Dexilant at the same time each day.
• Allow time to work: symptom relief may improve over several days; healing of irritated tissue may take longer.
• Track triggers: note which foods, drinks, or activities worsen symptoms.
• Use lifestyle measures: avoid late-night meals, elevate the head of the bed if advised, and maintain a healthy weight.
• Review your need: if symptoms are well controlled, ask whether dose reduction or step-down therapy is appropriate.
• Don’t double up on PPIs: unless your clinician advises it.
• Check with a pharmacist before starting new medicines (including over-the-counter products).

---

When to seek medical advice urgently

Contact a healthcare professional promptly (or seek urgent care) if you have any of the following:

• Chest pain that could be cardiac (especially if it spreads to the arm, jaw, or occurs with breathlessness)
• Difficulty swallowing, pain when swallowing
• Vomiting blood or passing black/tarry stools
• Unexplained weight loss
• Persistent vomiting or severe symptoms
• Symptoms that do not improve despite treatment

Heartburn can sometimes mimic other conditions, so it’s important not to ignore warning signs.

Alternative options (other treatments for reflux/acid-related symptoms)

If Dexilant isn’t suitable or doesn’t fully control symptoms, there are other options. Your pharmacist or GP can recommend the best approach based on your symptoms and history.

Medication alternatives

• Other PPIs (e.g., omeprazole, lansoprazole, pantoprazole, esomeprazole) — different release profiles and dosing schedules
• H2 receptor antagonists (e.g., famotidine) — may be used in some cases
• Antacids for quick, short-term relief (e.g., alginates/antacids) — often used as “rescue” treatment
• Alginate-based products — form a barrier to help reduce reflux episodes for some people

Non-medicine approaches

• Smaller meals and avoiding late eating
• Reducing foods/drinks that trigger symptoms
• Weight management if relevant
• Elevating the head of the bed
