1. What Dolintol is and what it is used for

Dolintol contains the active substance omeprazole. It belongs to a group of medicines called "proton pump inhibitors". These medicines work by reducing the amount of acid produced by the stomach.

Dolintol is used to treat the following conditions:

In adults:

• “Gastro-oesophageal reflux disease” (GORD). In this disorder, stomach acid passes into the oesophagus (the tube connecting the throat to the stomach), causing pain, inflammation, and heartburn.
• Ulcers in the upper part of the intestine (duodenal ulcer) or in the stomach (gastric ulcer).
• Ulcers infected with a bacterium called “Helicobacter pylori”. If you have this condition, your doctor may also prescribe antibiotics to treat the infection and allow the ulcer to heal.
• Ulcers caused by a group of medicines called NSAIDs (non-steroidal anti-inflammatory drugs). Dolintol may also be used to prevent ulcers from forming if you are taking NSAIDs.
• Excess stomach acid caused by a tumour in the pancreas (Zollinger-Ellison syndrome).

In children:

Children over 1 year of age and = 10 kg

• “Gastro-oesophageal reflux disease” (GORD). In this disorder, stomach acid passes into the oesophagus (the tube connecting the throat to the stomach), causing pain, inflammation, and heartburn.

In children, symptoms of the disease may include regurgitation of stomach contents into the mouth, vomiting, and inadequate weight gain.

Children over 4 years of age and adolescents

• Ulcers infected with a bacterium called “Helicobacter pylori”. If your child has this condition, their doctor may also prescribe antibiotics to treat the infection and allow the ulcer to heal. 110

2. What you need to know before taking Dolintol

Do not take Dolintol

• if you are allergic to omeprazole or any of the other ingredients of this medicine (listed in section 6).
• if you are allergic to medicines containing proton pump inhibitors (e.g. pantoprazole, lansoprazole, rabeprazole, esomeprazole).
• if you are taking a medicine containing nelfinavir (used for HIV infection).

Do not take Dolintol if any of the above apply to you. If you are unsure, speak with your doctor or pharmacist before taking Dolintol.

Warnings and precautions

Talk to your doctor or pharmacist before starting to take Dolintol.

Serious skin reactions have been reported with omeprazole treatment, including Stevens-Johnson syndrome, toxic epidermal necrolysis, drug reaction with eosinophilia and systemic symptoms (DRESS), and acute generalized exanthematous pustulosis (AGEP). Stop taking Dolintol and contact your doctor immediately if you experience any symptoms related to these serious skin reactions described in section 4.

Dolintol may mask symptoms of other conditions. Therefore, if you experience any of the following symptoms before starting or during treatment with Dolintol, consult your doctor immediately:

• Unintentional weight loss and difficulty swallowing.

• Stomach pain or indigestion.

• Vomiting food or vomiting blood.

• Black stools (indicating blood in the stool).

• Severe or persistent diarrhea, as omeprazole has been associated with a slight increase in infectious diarrhea.

• Severe liver problems.

• If you have ever had a skin reaction after treatment with a medicine similar to Dolintol used to reduce stomach acid.

• You are scheduled to have a specific blood test (Chromogranin A).

If you take Dolintol for a long period (more than 1 year), your doctor will likely perform periodic check-ups. Always report any new or unusual symptoms or circumstances during your visits.

Taking a proton pump inhibitor such as Dolintol, especially for more than one year, may slightly increase the risk of fractures of the hip, wrist, or spine. Inform your doctor if you have osteoporosis or are taking corticosteroids (which may increase the risk of osteoporosis).

If you develop a skin rash, especially in areas of skin exposed to sunlight, consult your doctor as soon as possible, as treatment with Dolintol may need to be discontinued. Remember to mention any other symptoms you may notice, such as joint pain.

Kidney inflammation may occur while taking omeprazole. Signs and symptoms may include reduced urine volume or blood in the urine and/or hypersensitivity reactions such as fever, rash, and joint stiffness. You should report these signs to your treating doctor.

This medicine may affect how your body absorbs vitamin B12, especially if taken for a long time. Contact your doctor if you notice any of the following symptoms, which could indicate low vitamin B12 levels:

• Extreme tiredness or lack of energy
• Tingling sensations
• Tongue pain or red, sore tongue, mouth ulcers
• Muscle weakness
• Vision changes
• Memory problems, confusion, depression

Children

Some children with chronic conditions may require long-term treatment, although this is not recommended. Do not give this medicine to children under 1 year of age or weighing < 10 kg.

Other medicines and Dolintol

Inform your doctor or pharmacist if you are currently taking, have recently taken, or might need to take any other medicines, including those obtained without a prescription. This is because Dolintol may affect how some medicines work, and some medicines may affect Dolintol.

Do not take Dolintol if you are taking a medicine containing nelfinavir (used to treat HIV infection).

• A widespread red, scaly rash with lumps under the skin and blisters accompanied by fever. Symptoms usually appear at the beginning of treatment (acute generalized exanthematous pustulosis). (rare)

• Yellowing of the skin, dark urine and tiredness, which may be signs of liver problems.

Other adverse effects are:

Frequent adverse effects (may affect up to 1 in 10 people)

• Headache.

• Abnormalities in blood tests used to monitor liver function.
• Skin rash, hives and itching.
• General feeling of being unwell and lack of energy.

Rare adverse effects (may affect up to 1 in 1,000 people)

• Blood disorders, such as a decrease in white blood cells or platelets. This may cause weakness or bruising and increase the likelihood of developing infections.
• Low sodium levels in the blood. This may cause weakness, vomiting and cramps.
• Restlessness, confusion or depression.
• Taste disturbances.
• Vision problems, such as blurred vision.
• Sudden sensation of shortness of breath (bronchospasm).

• Increased sweating.

Very rare adverse effects (may affect up to 1 in 10,000 people)

• Blood count abnormalities, such as agranulocytosis (lack of white blood cells).
• Aggressiveness.
• Seeing, feeling or hearing things that are not real (hallucinations).
• Serious liver problems leading to liver failure and brain inflammation.
• Erythema multiforme. Muscle weakness.
• Enlargement of the breasts in males.

Frequency not known (cannot be estimated from available data)

• Inflammation in the intestine (causing diarrhoea).
• If you are being treated with omeprazole for more than three months, your blood magnesium levels may decrease. Low magnesium levels may manifest as fatigue, involuntary muscle contractions, disorientation, seizures, dizziness or increased heart rate. If you experience any of these symptoms, contact your doctor immediately. Low magnesium levels may also lead to decreased levels of potassium or calcium in the blood. Your doctor may decide to perform periodic blood tests to monitor your magnesium levels.
• Skin rash, possibly with joint pain.

In very rare cases, omeprazole may affect the white blood cells and cause immunodeficiency. If you develop an infection with symptoms such as fever with a very poor general condition or fever with signs of local infection, such as neck, throat or mouth pain or difficulty urinating, you should consult your doctor as soon as possible for a blood test to rule out a deficiency in white blood cells (agranulocytosis). It is important that you provide information about the medicines you are taking at that time.
