Vonozan 20mg Tablets

Vonoprazan is a potassium-competitive acid blocker (PCAB). It reduces the amount of acid your stomach makes. It is used to:

• heal erosive oesophagitis (acid damage to the food pipe) and keep it healed
• relieve heartburn
• clear Helicobacter pylori, a germ that causes stomach ulcers, together with antibiotics

Take it exactly as your doctor or pharmacist tells you, once or twice a day depending on your condition.

• It can be taken with or without food, at about the same time each day.
• Swallow the tablet whole. Do not split, chew or crush it.
• If you miss a dose, ask your pharmacist what to do: on once-daily dosing, skip it if more than 12 hours have passed; on twice-daily dosing, skip it if more than 4 hours have passed. Never take two doses together.

Common side effects include:

• diarrhoea
• bloating or stomach pain
• feeling sick or indigestion

Get medical help straight away if you have:

• watery stools, stomach pain and fever that do not go away
• a rash with blistering, peeling or bleeding skin
• passing less urine or blood in the urine
• yellow skin or eyes, or dark urine
• bone pain or a broken bone
• an irregular heartbeat, muscle spasms, shaking or seizures
• swelling of the face or throat, or trouble breathing

Check with your doctor or pharmacist before taking it if you:

• have kidney or liver disease
• have thin bones (osteopenia or osteoporosis)
• have low vitamin B12, calcium, magnesium or potassium
• are pregnant, planning a pregnancy or breastfeeding
