Omeprazole is a medication used to treat conditions caused by excess stomach acid, such as heartburn, stomach ulcers, and reflux disease. While generally well-tolerated, it can cause several side effects, including headaches, nausea, vomiting, and diarrhoea. Long-term use of omeprazole may lead to more severe side effects such as respiratory infections, bone fractures, and pneumonia. One notable side effect associated with omeprazole is muscle cramps or spasms, which may be related to hypomagnesemia (low magnesium levels in the blood). This side effect is more likely to occur with prolonged use of omeprazole, especially when taken concurrently with certain other medications.

What You'll Learn

Long-term use of omeprazole can cause hypomagnesaemia (low magnesium in the blood)
Omeprazole is a medication used to treat conditions that cause excessive stomach acid, such as heartburn, stomach ulcers, and reflux disease. It belongs to a group of medications called proton pump inhibitors (PPIs), which work by reducing the amount of acid in the stomach. While omeprazole is generally well-tolerated, long-term use can lead to specific side effects.
One of the potential long-term side effects of omeprazole is hypomagnesaemia, or low magnesium levels in the blood. This side effect is more likely to occur when omeprazole is taken for more than a year, especially at normal doses of 20-40 mg per day. Low magnesium levels can cause a range of symptoms, including muscle cramps, muscle twitches, and muscle spasms or tetany. Other symptoms of hypomagnesaemia include tiredness, confusion, dizziness, an irregular heartbeat, and even seizures.
The risk of developing hypomagnesaemia while taking omeprazole is increased when it is taken in conjunction with certain other medications, such as digoxin (Lanoxin®) or specific diuretics or "water pills". It is important for patients taking omeprazole to be aware of this potential side effect and to monitor their magnesium levels, especially with long-term use. Regular health check-ins with a doctor are recommended for those taking omeprazole for extended periods.
If you experience any symptoms of hypomagnesaemia, such as muscle cramps or irregular heartbeat, it is crucial to consult a healthcare professional immediately. They may advise discontinuing omeprazole treatment or adjusting the dosage to alleviate the side effects. In most cases, magnesium levels normalise after stopping or reducing the intake of omeprazole.
It is worth noting that long-term use of omeprazole has also been associated with an increased risk of other side effects, such as bone fractures, respiratory infections, and, in rare cases, stomach cancer. Therefore, it is generally recommended to take omeprazole at the lowest effective dose for the shortest duration necessary to manage the underlying condition.

Omeprazole side effects include muscle spasms
Omeprazole is a medication used to treat conditions that cause excessive stomach acid, such as heartburn, stomach ulcers, and reflux disease. While generally well-tolerated, it can cause various side effects, including muscle spasms or cramps.
One of the most common side effects of omeprazole is headaches, affecting around 7% of people taking it. Additionally, it can cause stomach-related side effects such as nausea, vomiting, and diarrhea. These side effects are typically mild and may not require medical attention. However, if they persist or become bothersome, it is recommended to consult a doctor or pharmacist.
Long-term use of omeprazole, particularly for more than a year, can lead to more serious side effects. These include a higher risk of bone fractures, respiratory infections, and pneumonia. Prolonged use may also result in low magnesium levels in the blood (hypomagnesemia), which can cause muscle spasms or cramps, as well as other symptoms such as tremors, unusual tiredness, and an irregular heartbeat.
It is important to be vigilant about any unusual symptoms that occur while taking omeprazole. If you experience muscle spasms or cramps, along with convulsions, seizures, an irregular heartbeat, tremors, or unusual tiredness, it is crucial to seek medical advice promptly. Your doctor may advise you to stop taking omeprazole and recommend alternative treatments or medications.
While omeprazole is a beneficial medication for managing stomach acid-related conditions, it is always advisable to be aware of its potential side effects and to consult a healthcare professional if any adverse symptoms arise.

Prolonged use of omeprazole may increase the risk of fractures
Omeprazole is a medication used to treat conditions that cause excessive stomach acid, such as heartburn, stomach ulcers, reflux disease, and gastroesophageal reflux disease (GERD). While generally well-tolerated, omeprazole, like all medications, carries certain risks and side effects. One notable side effect is the potential increase in the risk of fractures with prolonged use.
Proton pump inhibitors (PPIs), including omeprazole, have been linked to an increased risk of bone fractures, particularly with long-term use. This risk is more pronounced in individuals aged 50 and above, those receiving high doses of the medication, and those who have been taking it for a year or more. The fractures most commonly associated with omeprazole use occur in the hip, wrist, and spine. Therefore, it is advisable to consult a doctor immediately if you experience severe bone pain, difficulty walking, or problems with sitting.
The mechanism underlying the association between omeprazole and an increased risk of fractures is suggested to be related to its impact on magnesium levels in the body. Long-term use of omeprazole has been linked to hypomagnesaemia, or low magnesium levels in the blood. This is a significant concern as magnesium plays a crucial role in bone health and strength. Depleted magnesium levels can lead to weakened bones that are more susceptible to fractures.
Additionally, omeprazole may also negatively affect calcium absorption, further contributing to bone health issues. Calcium is essential for maintaining strong and healthy bones, and reduced absorption can increase the risk of fractures. It is important to note that the impact of omeprazole on calcium absorption is not yet fully understood, and more research is needed to establish a definitive link.
To mitigate the potential risk of fractures associated with long-term omeprazole use, healthcare professionals recommend taking the lowest effective dosage for the shortest duration necessary. Regular health check-ups are also advised for those who have been taking omeprazole for extended periods. By monitoring magnesium levels and bone health, doctors can help identify and address any potential issues before they lead to more serious complications, such as fractures.

Omeprazole may cause convulsions (seizures)
Omeprazole is a medication used to treat conditions caused by excess stomach acid, such as heartburn, stomach ulcers, and reflux disease. While it is an effective treatment, it can cause several side effects, and in rare cases, may lead to muscle cramps or convulsions (seizures).
Side effects of omeprazole are more common in those taking the medication for more than a year, and the risk of certain side effects increases with prolonged use. For example, patients taking omeprazole for over a year may experience a vitamin B12 deficiency, which can cause muscle cramps, among other symptoms. Additionally, long-term use of omeprazole may increase the risk of convulsions or seizures.
Convulsions or seizures are not a common side effect of omeprazole, but they can occur in rare cases. Patients taking omeprazole who experience convulsions or seizures should seek immediate medical attention. It is important to note that an overdose of omeprazole can also cause seizures, so it is crucial to follow the prescribed dosage and not exceed the recommended amount.
While muscle cramps are not listed as a direct side effect of omeprazole, the medication can cause low magnesium levels in the blood if taken for more than three months. Low magnesium levels can then lead to muscle twitches and cramps, among other symptoms. Therefore, there is an indirect link between omeprazole and muscle cramps.
It is always advisable to consult a doctor or pharmacist if you experience any side effects, including muscle cramps or convulsions, while taking omeprazole. They can advise on managing side effects and determine whether the benefits of the medication outweigh the risks in your particular case.

Omeprazole may increase the risk of stomach cancer
Omeprazole is a medication that treats conditions caused by excess stomach acid, such as heartburn, stomach ulcers, and reflux disease. It belongs to a class of medications known as proton pump inhibitors (PPIs). While PPIs are generally considered safe for short-term use, typically less than three months, concerns have been raised about their potential link to stomach cancer with prolonged usage.
Several studies have investigated the association between long-term PPI use and an increased risk of gastric cancer. Some research suggests that PPIs increase the systemic level of gastrin, a hormone linked to carcinogenesis. One study found that PPI use was associated with a higher risk of gastric cancer (RR 1.80, 95% CI, 1.46-2.22, p < 0.001) compared to non-users. Another systematic review and meta-analysis, which examined the use of omeprazole and lansoprazole, also showed a positive association with gastric cancer (HR: 1.17, 95% CI: 0.74, 1.85; HR: 1.21, 95% CI: 0.71-2.08).
Furthermore, when considering the intensity of PPI use, higher doses and longer durations were found to correlate with an elevated risk of gastric cancer. Lee et al. demonstrated that the risk of gastric cancer was significantly higher when PPIs were taken at the highest dose and for extended periods (OR: 2.95, 95% CI: 1.23-7.90). Additionally, two studies indicated a gender difference in risk, with female patients showing a slightly higher risk of gastric cancer associated with PPI therapy than male patients.
However, it is important to note that the mechanisms underlying the association between PPIs and cancer risk are not yet fully understood. Possible explanations include changes in the gut microbiome, increased gastrin output, proliferation of enterochromaffin-like cells, and non-specific binding to protein targets associated with cancer. Further studies are needed to comprehensively elucidate these mechanisms and the potential harm posed by long-term PPI consumption.
