Interactions between your drugs

Major

enalapril valsartan

Applies to: Teczem (diltiazem / enalapril) and amlodipine / hydrochlorothiazide / valsartan

Using enalapril together with valsartan may increase the risk of side effects such as low blood pressure, kidney function impairment, and a condition called hyperkalemia (high blood potassium). In severe cases, hyperkalemia can lead to kidney failure, muscle paralysis, irregular heart rhythm, and cardiac arrest. You may be more likely to develop hyperkalemia while taking these medications if you are elderly, dehydrated, or have kidney disease, diabetes, or advanced heart failure. Regular or long-term use of nonsteroidal anti-inflammatory drugs such as ibuprofen or naproxen (Aleve) may also increase your risk. It is important that you maintain adequate fluid intake during treatment with these medications. Talk to your doctor if you have any questions or concerns. Your doctor may already be aware of the risks, but has determined that this is the best course of treatment for you and has taken appropriate precautions and is monitoring you closely for any potential complications. In addition, ask your doctor if it is necessary for you to limit consumption of potassium-rich foods such as tomatoes, raisins, figs, potatoes, lima beans, bananas, plantains, papayas, pears, cantaloupes, mangoes, and potassium-containing salt substitutes. You should seek medical attention if you experience nausea, vomiting, weakness, confusion, tingling of the hands and feet, feelings of heaviness in the legs, a weak pulse, or a slow or irregular heartbeat, as these may be symptoms of hyperkalemia. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

enalapril hydroCHLOROthiazide

Applies to: Teczem (diltiazem / enalapril) and amlodipine / hydrochlorothiazide / valsartan

Although enalapril and hydroCHLOROthiazide are frequently combined together, their effects may be additive on lowering your blood pressure. You may need a dose adjustment or special tests to safely take both medications. Contact your doctor if you have a reduced heart rate, dizziness, fainting, or headaches. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

dilTIAZem amLODIPine

Applies to: Teczem (diltiazem / enalapril) and amlodipine / hydrochlorothiazide / valsartan

DilTIAZem may increase the blood levels of amLODIPine. You may be more likely to experience serious side effects such as irregular heart rhythm, fluid retention, swelling, heart failure, and excessively low blood pressure. You may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. You should seek medical attention if you develop dizziness or fainting; sudden, unexplained weight gain; swelling of the hands, ankles, or feet; chest pain; or difficulty breathing during treatment with these medications. Avoid driving or operating hazardous machinery until you know how the medications affect you, and use caution when getting up from a sitting or lying position. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

dilTIAZem food

Applies to: Teczem (diltiazem / enalapril)

Alcohol can lower your blood pressure and add to the effects of dilTIAZem. You may experience dizziness, lightheadedness, fainting, or a rapid heartbeat if you drink alcohol with dilTIAZem, especially when you first start taking the medication or just after a dose increase. Grapefruit juice may also increase the effects of dilTIAZem in some people by increasing its levels in the blood. You may want to limit alcohol intake and avoid excessive consumption of grapefruit and grapefruit juice during treatment with dilTIAZem. However, if you have been regularly consuming grapefruit or grapefruit juice with dilTIAZem, do not alter the amounts of these products in your diet without first talking to your doctor or other healthcare professional. Contact your doctor if your condition changes or you experience increased side effects of dilTIAZem such as headache, irregular heartbeat, swelling, unexplained weight gain, or chest pain. Orange juice is not expected to interact.

Therapeutic duplication warnings

Therapeutic duplication is the use of more than one medicine from the same drug category or therapeutic class to treat the same condition. This can be intentional in cases where drugs with similar actions are used together for demonstrated therapeutic benefit. It can also be unintentional in cases where a patient has been treated by more than one doctor, or had prescriptions filled at more than one pharmacy, and can have potentially adverse consequences.
