Aspirin/omeprazole - oral
Aspirin/omeprazole - oral
This combination product contains two medications: aspirin and omeprazole. It is used to reduce the risk of stroke or heart attack in people who have had "mini-strokes" (transient ischemic attacks), or a stroke due to a blood clot, or who have heart disease. This product is used by people who are at risk for developing ulcers while taking aspirin.
Aspirin belongs to a class of drugs known as antiplatelets. It has many uses, such as for pain relief or to reduce a fever. In low doses (such as this product), it is used to prevent harmful blood clots that can cause a stroke or heart attack. It works by stopping platelets in your blood from clumping together to form clots. Omeprazole belongs to a class of drugs known as proton pump inhibitors (PPIs). It works by decreasing the amount of acid your stomach makes. This effect helps prevent ulcers and other stomach-related problems (such as heartburn) that can be caused by aspirin.
This medication contains a delayed-release form of aspirin. It should not be used to treat conditions that require an immediate-release form of aspirin, such as right after a heart attack or before certain heart procedures (such as percutaneous coronary intervention-PCI). Also, this combination product is not the same as taking aspirin and omeprazole separately.
Read the Medication Guide provided by your pharmacist before you start taking this medication and each time you get a refill. If you have any questions, ask your doctor or pharmacist.
Take this medication by mouth as directed by your doctor, usually once daily at least 60 minutes before a meal. Swallow the tablet whole with a full glass of water (8 ounces or 240 milliliters) unless your doctor directs you otherwise. Do not lie down for at least 10 minutes after taking this medication. Do not split, crush, chew, or dissolve the tablet. Doing so can release all of the drug at once, increasing the risk of side effects.
The dosage is based on your medical condition and response to treatment. Use this medication regularly to get the most benefit from it. To help you remember, take it at the same time each day.
Upset stomach or heartburn may occur. If either of these effects lasts or gets worse, tell your doctor or pharmacist promptly.
Remember that this medication has been prescribed because your doctor has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

If you have these symptoms, do not use anti-diarrhea or opioid products because they may make symptoms worse.
Rarely, proton pump inhibitors (such as omeprazole) have caused vitamin B-12 deficiency. The risk is increased if they are taken every day for a long time (3 years or longer). Tell your doctor right away if you develop symptoms of vitamin B-12 deficiency (such as unusual weakness, sore tongue, or numbness/tingling of the hands/feet).

Before using this medication, tell your doctor or pharmacist your medical history, especially of:
This medicine may cause stomach bleeding. Daily use of alcohol and tobacco while using this medicine may increase your risk for stomach bleeding. Limit alcohol and stop smoking. Ask your doctor or pharmacist about how much alcohol you may safely drink.

Proton pump inhibitors (such as omeprazole) may increase your risk for bone fractures, especially with longer use, higher doses, and in older adults. Talk with your doctor or pharmacist about ways to prevent bone loss/fracture, such as by taking calcium (such as calcium citrate) and vitamin D supplements.
Older adults may be more sensitive to the side effects of this drug, especially bone loss and fractures (see above), bleeding, and C. difficile infection (see Side Effects section).
This drug contains aspirin. Children and teenagers younger than 18 years should not take aspirin if they have chickenpox, flu, or any undiagnosed illness or if they have recently received a vaccine. In these cases, taking aspirin increases the risk of Reye's syndrome, a rare but serious illness.
Aspirin is not recommended for use to treat pain or fever during pregnancy. Before using this medication, women of childbearing age should talk with their doctor(s) about the benefits and risks. Tell your doctor if you are pregnant or if you plan to become pregnant. This medication may harm an unborn baby and cause problems with normal labor/delivery. It is not recommended for use in pregnancy from 20 weeks until delivery. If your doctor decides that you need to use this medication between 20 and 30 weeks of pregnancy, you should use the lowest effective dose for the shortest possible time. In some cases, low-dose aspirin (usually 81-162 milligrams a day) may be used safely during pregnancy to prevent certain conditions. Talk to your doctor for more details.
Aspirin passes into breast milk. When used in large amounts (such as to treat pain or fever), it may harm a nursing infant and breast-feeding while using this drug is not recommended. However, low-dose aspirin for heart attack or stroke prevention may be used if directed by your doctor. Consult your doctor before breast-feeding.
Drug interactions may change how your medications work or increase your risk for serious side effects. This document does not contain all possible drug interactions. Keep a list of all the products you use (including prescription/nonprescription drugs and herbal products) and share it with your doctor and pharmacist. Do not start, stop, or change the dosage of any medicines without your doctor's approval.
Some products that may interact with this drug include:
Check all prescription and nonprescription medicine labels carefully since many medications contain pain relievers/fever reducers (aspirin, NSAIDs such as ibuprofen or naproxen). These drugs are similar to this medication and may increase your risk of side effects if taken together. Ask your doctor or pharmacist for more details.
Some products need stomach acid so that the body can absorb them properly. Omeprazole decreases stomach acid, so it may change how well these products work. Some affected products include atazanavir, erlotinib, levoketoconazole, nelfinavir, pazopanib, rilpivirine, sparsentan, certain azole antifungals (itraconazole, ketoconazole, posaconazole), among others.
Other medications can affect the removal of omeprazole from your body, which may affect how this product works. Examples include rifampin, St John's wort, among others.
Omeprazole is very similar to esomeprazole. Do not use any medications containing esomeprazole while using omeprazole.
This medication may interfere with certain lab or medical tests, possibly causing false test results. Make sure lab personnel and all your doctors know you use this drug.
If someone has overdosed and has serious symptoms such as passing out or trouble breathing, call 911. Otherwise, call a poison control center right away.
