Taking antacids at the same time as omeprazole can stop the omeprazole from working properly. This is because antacids can interfere with how the omeprazole tablet or capsule dissolves and how much of the medicine your body absorbs. If the omeprazole isn't absorbed correctly, it won't be as effective at reducing your stomach acid.

Por qué sucede esto
Omeprazole is often designed with a special coating to protect it from stomach acid so it can be absorbed further down in the digestive tract. Antacids change the acidity level of the stomach, which can cause the omeprazole to break down too early or not dissolve correctly, reducing the amount of medicine that reaches your bloodstream.
Lo que deberías hacer
Volver al contenidoYou should separate the doses of these two medicines. It is best to take your omeprazole first (usually in the morning) and wait at least 2 hours before taking an antacid. This gives the omeprazole enough time to be absorbed by your body.

Precauciones importantes
Volver al contenidoDiarrea severa
Omeprazole can increase your risk of developing a serious bacterial infection called C. difficile, which causes severe, persistent watery diarrhoea and stomach cramps.
Enmascarar síntomas graves
These medicines can hide the symptoms of more serious conditions. You must see a doctor if you have unexplained weight loss, persistent vomiting, or difficulty swallowing.
Interacciones de medicamentos
Do not take these two medicines at the same time. Antacids can stop omeprazole from being absorbed properly; leave a gap of at least 2 hours between them.
Lupus (SLE)
Consulte a un médico si desarrolla una erupción cutánea, especialmente en áreas expuestas al sol, ya que el omeprazol puede desencadenar o empeorar una rara condición autoinmune llamada Lupus Eritematoso Cutáneo Subagudo.
Advertencias sobre alimentos y bebidas
Volver al contenidoAlcohol
It is best to avoid or strictly limit alcohol when taking these medicines. Alcohol increases the amount of acid your stomach produces, which can make your symptoms worse and counteract the benefits of the medicine. Alcohol can also irritate the stomach lining.
Productos lácteos (Leche, Queso, Yogur)
Some antacids can interact with the calcium in dairy products. If you are taking antacids that contain calcium, consuming large amounts of dairy can lead to 'milk-alkali syndrome', which causes high calcium levels in the blood and potential kidney issues. Check your antacid label for calcium content.
Caffeine (Coffee, Tea, Cola)
Caffeine can trigger or worsen symptoms of acid reflux and indigestion by relaxing the muscle at the bottom of the food pipe. This may make your medication feel less effective.
Fruit juices and acidic drinks
Avoid taking antacids with acidic drinks like orange, lemon, or grapefruit juice. These can increase the absorption of aluminium (found in many antacids) into the bloodstream, which can be harmful, especially if you have kidney problems. Acidic drinks also worsen the symptoms the medicine is trying to treat.
Horario general de las comidas
El omeprazol funciona mejor si lo tomas de 30 a 60 minutos antes de una comida, preferiblemente el desayuno. Tomarlo con comida puede retrasar la rapidez con la que el medicamento comienza a hacer efecto.

Can I take Lisinopril and Potassium together?
Taking lisinopril and potassium supplements together can cause the levels of potassium in your blood to become dangerously high (a condition called hyperkalaemia). While your body needs potassium for your heart and muscles to work, too much of it can lead to serious heart rhythm problems or even cause the heart to stop. Symptoms of high potassium can include muscle weakness, tingling sensations, or palpitations, but often there are no symptoms until the level is very high.

Can I take Amlodipine and Ramipril together?
Taking these two medicines together can cause your blood pressure to drop lower than usual. This might make you feel dizzy, lightheaded, or faint, especially when you stand up quickly. It can also increase the risk of your kidneys not working as well as they should or cause a rise in potassium levels in your blood.
