Omeprazole is a medication used to decrease the amount of acid in your stomach. It is used to manage gastroesophageal reflux disease (condition where your stomach acid moves up your esophagus), gastric ulcers and other conditions affected by stomach acid production. According to Drugs.com, omeprazole is available as a capsule and its initial dose is 20 milligrams daily. Your doctor may decide to increase this dosage depending upon your condition.
Common Side Effects
According to Drugs.com, omeprazole can cause stomach pain, flatulence (gas) and diarrhea. This stomach pain may be stabbing or dull in nature. Gas is harmless but may be embarrassing in social situations. You may also experience nausea or vomiting. Loose stools can make you dehydrated and as a result, you can develop a headache. Drink plenty of fluids to prevent dehydration and call your doctor if any of these symptoms worsen or continue.
Dangerous Side Effects
MedlinePlus says that omeprazole can lead to a rash and hives. Typically, this rash can appear on any part of your body. It may be inflamed and intensely itchy. In some cases, omeprazole can causes itchy red bumps on your skin, known as hives. Sometimes, omeprazole can provoke swelling of your extremities, face, throat and lips. Swelling of your throat can cut off your air supply and lead to difficulty breathing. Omeprazole can also cause difficulty swallowing. Eating foods or drinking liquids can cause you to choke. Muscle cramps, spasms and burning of your hands or feet are some other dangerous side effects of omeprazole use. Inform your doctor when you have these symptoms as they can all be life threatening.
Rare Side Effects
According to the Mayo Clinic, you may seldom develop joint pain, red eyes, a sore throat and extreme fatigue or weakness when using omeprazole. A fever, mouth sores, appetite loss, peeling skin, bruising and bleeding are other rare side effects of omeprazole. Call your doctor at once when you have these symptoms.
Other Side Effects
Chest pain, constipation, a lost voice, sneezing and drowsiness are other side effects of omeprazole, says the Mayo Clinic. Chest pain is the result of decreased blood flow to your heart. Constipation is a benign side effect that requires attention if you haven't had a bowel movement in at least three to five days. Avoid driving or participating in projects that require your full attention if you are drowsy.
