An interaction between two medications does not always mean that you must stop taking one of them. Speak to your doctor about how any drug interactions are being managed or should be managed.
Medications other than those listed above may interact with Olex (Omeprazole). Tell your doctor or prescriber about all prescription, over-the-counter (non-prescription), and herbal medications you are taking. Also tell them about any supplements you take. Since caffeine, alcohol, the Nicotine from cigarettes, or street drugs can affect the action of many medications, you should let your prescriber know if you use them.
Before you begin using a medication, be sure to inform your doctor of any medical conditions or Allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use Olex (Omeprazole).
Diarrhea: When gastric acid is decreased, the number of bacteria normally in the digestive system increases. Occasionally, this can cause serious infection in the digestive tract. If you experience watery, foul-smelling bowel movements after starting to take Olex (Omeprazole), contact your doctor as soon as possible.
Fluid and electrolyte balance: Olex (Omeprazole), like other PPIs, may cause the levels of electrolytes such as potassium, sodium, magnesium, chloride, and calcium in the blood to change while taking Olex (Omeprazole). If you experience symptoms of fluid and electrolyte imbalance such as muscle pains or cramps; dry mouth; numb hands, feet, or lips; or racing heartbeat, contact your doctor as soon as possible. Your doctor will do blood tests regularly to monitor the levels of these electrolytes in your blood while you are taking Olex (Omeprazole).
Liver function: Liver disease or reduced liver function may cause Olex (Omeprazole) to build up in the body. If you have liver problems, discuss with your doctor how Olex (Omeprazole) may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Olex (Omeprazole), and whether any special monitoring is needed. Your doctor may want to test your liver function regularly with blood tests while you are taking Olex (Omeprazole). People with severe liver disease should generally not take more than 20 mg of Olex (Omeprazole) daily.
Methotrexate interaction: Olex (Omeprazole), like other medications in this group, may interact with methotrexate when the two medications are used at the same time. This combination may lead to higher than expected amounts of methotrexate in the body and can cause serious side effects, including kidney damage, irregular heartbeat, Anemia, or infection. If you take Olex (Omeprazole) and are also going to receive a dose of methotrexate, discuss with your doctor how Olex (Omeprazole) may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Olex (Omeprazole), and whether any special monitoring is needed.
Osteoporosis-related fractures: Studies suggest that the use of Olex (Omeprazole), like other PPIs, may be related to an increase risk of fractures, particularly for people who take Olex (Omeprazole) for a year or longer. The lowest dose of Olex (Omeprazole) to control the symptoms, taken for the shortest period of time is less likely to cause these problems.
Severe stomach problems: If you have recurrent vomiting, difficulty swallowing, blood in the stool, coughing up of blood, or significant unintentional weight loss, check with your doctor immediately. These symptoms may be signs of a more serious stomach problem.
Subacute cutaneous Lupus erythematosus (SCLE): Olex (Omeprazole), like other PPIs, has been rarely associated with SCLE, an autoimmune disease. If you develop any skin lesions, especially in sun-exposed skin areas, and if accompanied by muscle aches or pains, contact your doctor immediately.
Vitamin B12: Long-term use of Olex (Omeprazole) may lead to vitamin B12 deficiency. If you are a vegetarian or have low vitamin B12 levels, discuss with your doctor whether any special monitoring is required.
Pregnancy: Olex (Omeprazole) should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking Olex (Omeprazole), call your doctor immediately.
