Digestion is an important process that allows for food absorption. Sometimes, the intestines become inflamed or stomach acid backs up the digestive tract into the esophagus and mouth. In some cases, cancer cells can grow on certain organs such as the stomach and lead to digestion problems. Medicines exist to manage digestive disorders.
Adalimumab
Adalimumab, commonly known as Humira, is a medication used to treat Crohn's disease, a specific type of inflammatory bowel disease characterized by chronic diarrhea and stomach cramping. Specifically, adalimumab is a tumor necrosis factor (TNF) inhibitor--it works to decrease TNF, substances necessary for inflammation to occur, says MedlinePlus.
Adalimumab's side effects typically include stomach pain, nausea, back pain and headache as well as bruising, redness, swelling or pain at the spot in which adalimumab was injected. These effects should last only about a week; call a physician if they remain for more than seven to 14 days. Serious side effects of adalimumab include leg weakness, dizziness, trouble breathing or swallowing, shortness of breath, chest pain, tingling or numbness, a rash, sore throat, fever, chills, dizziness and visual problems. Inform a physician immediately when adalimumab causes these effects.
Adalimumab is available as a liquid that is injected one time, every other week, MedlinePlus reports.
Omeprazole
Omeprazole, commonly known as Prilosec, is a medication used to manage gastroesophageal reflux disease (GERD), a condition in which the acid in the stomach backs up into the esophagus and throat. According to Drugs.com, omeprazole's common side effects include gas (flatulence), stomach pain, nausea, headache, vomiting and diarrhea. These symptoms should last for at most one week. Allergic reactions to omeprazole include hives, difficulty breathing and swelling of the face, tongue or lips.
Taking omeprazole while suffering from frequent chest pain, black or bloody stools, heartburn for more than three months, unintentional weight loss and trouble swallowing may exacerbate these conditions. Inform your physician if you decide to take omeprazole. Omeprazole is available over the counter and typically is taken once a day for 14 days.
