Major:

dipyridamole enoxaparin

Applies to: dipyridamole and Lovenox (enoxaparin)

Using dipyridamole together with enoxaparin may increase the risk of bleeding, including severe and sometimes fatal hemorrhage.

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.

You should seek immediate medical attention if you experience any unusual bleeding or bruising, or have other signs and symptoms of bleeding such as:

  • dizziness
  • lightheadedness
  • red or black, tarry stools
  • coughing up or vomiting fresh or dried blood that looks like coffee grounds
  • severe headache
  • weakness

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.

Food/lifestyle interactions

Moderate food/lifestyle interactions

Moderate:

dipyridamole Food/Lifestyle

Applies to: dipyridamole

Caffeine may interfere with the effects of dipyridamole in dilating the arteries.

You should avoid caffeine-containing products for at least 24 hours before an imaging procedure involving dipyridamole given by injection.

However, no special precaution is necessary if you are taking dipyridamole orally for maintenance.

Moderate:

dipyridamole Caffeine

Applies to: dipyridamole

Ask your doctor before using dipyridamole together with caffeine. Using these medications together can decrease the effects of dipyridamole.

It is recommended that caffeine including caffeine be avoided for 12 to 24 hours before dipyridamole administration. You may need a dose adjustment or special test if you use both medications.

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.

Disease interactions

29 potential interactions Applies to: 22 conditions, including High Blood Pressure, Asthma, COPD, Arrhythmia, and Hypotension.

Abnormal Uterine Bleeding

Major:

Lovenox

The enoxaparin in Lovenox has a major potential interaction with Abnormal Uterine Bleeding.

The use of heparin is contraindicated in patients with uncontrollable active bleeding, except when the bleeding is due to disseminated intravascular coagulation. Hemorrhage can occur at virtually any site in patients receiving heparin. An unexplained drop in hematocrit or blood pressure, or any other unexplained symptom, should lead to serious consideration of a hemorrhagic event. Therapy with heparin should be used with extreme caution in patients with known bleeding disorders or disease states that may predispose to hemorrhage during heparin administration, including hemophilia, thrombocytopenia, certain vascular purpuras, ulcerative gastrointestinal lesions, diverticulitis, ulcerative colitis, severe liver disease, subacute bacterial endocarditis, severe hypertension, myeloproliferative disorders, and threatened abortion. Blood coagulation tests (e.g., whole blood clotting time, activated partial thromboplastin time) should be performed at appropriate intervals during full-dose heparin administration. In addition, periodic platelet counts, hematocrits, and tests for occult blood in stool are recommended during the entire course of heparin therapy. There is usually no need to monitor coagulation parameters in patients receiving low-dose heparin, except in patients undergoing major surgery. For low molecular weight heparin (LMWH), coagulation tests such as prothrombin time (PT) and aPTT are relatively insensitive measures of LMWH activity and not suitable for routine monitoring. Anti-Factor Xa may be used to monitor the anticoagulant effect of LMWH in patients with significant renal impairment, abnormal coagulation parameters, or bleeding during therapy.

Arrhythmia

Moderate:

dipyridamole

Dipyridamole has a moderate potential interaction with Arrhythmia.

Serious adverse reactions associated with the administration of intravenous dipyridamole have included cardiac death, fatal and non- fatal myocardial infarction, ventricular fibrillation, symptomatic ventricular tachycardia, stroke, transient cerebral ischemia, seizures, anaphylactoid reaction and bronchospasm. There have been reported cases of asystole, sinus node arrest, sinus node depression and conduction block. Patients with abnormalities of cardiac impulse formation/conduction or severe coronary artery disease may be at increased risk for these events. Caution is recommended.

Asthma

Major:

dipyridamole

Dipyridamole has a major potential interaction with Asthma.

Dipyridamole is a phosphodiesterase inhibitor and can exacerbate bronchospasm, particularly in patients with reactive airway disease and/or chronic obstructive pulmonary disease (COPD).

Heparin-Induced Thrombocytopenia

Major:

Lovenox

The enoxaparin in Lovenox has a major potential interaction with Heparin-Induced Thrombocytopenia.

The use of heparin is contraindicated in patients with severe thrombocytopenia. Acute thrombocytopenia can occur in patients receiving heparin, with a reported incidence of up to 30%. Platelet counts should be obtained before and periodically during heparin administration, including regular and repeated use of heparin flush solutions if given for longer than 5 days. Mild thrombocytopenia with counts above 100,000/mm3 may remain stable or reverse despite continued heparin administration. However, thrombocytopenia of any degree should be closely monitored. Therapy should be discontinued if the count falls below 100,000/mm3 or if recurrent thrombosis develops, and an alternative, nonheparin anticoagulant (e.g., argatroban, bivalirudin, lepirudin) administered if necessary. Heparin-induced thrombocytopenia (HIT) is a serious antibody-mediated reaction resulting from irreversible aggregation of platelets. HIT may progress to the development of venous and arterial thromboses, a condition referred to as heparin-induced thrombocytopenia and thrombosis (HITT). Thrombotic events may also be the initial presentation for HITT, and may include deep vein thrombosis, pulmonary embolism, cerebral vein thrombosis, limb ischemia, stroke, myocardial infarction, mesenteric thrombosis, renal artery thrombosis, skin necrosis, gangrene of the extremities that may lead to amputation, and possibly death. Both HIT and HITT can occur up to several weeks after the discontinuation of heparin therapy. Patients presenting with thrombocytopenia or thrombosis after discontinuation of heparin should be evaluated for HIT and HITT. Following an episode, any future use of heparin should be avoided, and use of low-molecular weight heparin should consider the potential for cross-reactivity with the HIT antibody and approached with extreme caution, if not otherwise contraindicated.

High Blood Pressure

Major:

Lovenox

The enoxaparin in Lovenox has a major potential interaction with High Blood Pressure.

Heparin should be used with extreme caution in patients with uncontrolled or severe hypertension as these conditions may predispose the patient to hemorrhage during heparin administration. Blood coagulation tests (e.g., whole blood clotting time, activated partial thromboplastin time) should be performed at appropriate intervals during full-dose heparin administration. In addition, periodic platelet counts, hematocrits, and tests for occult blood in stool are recommended during the entire course of heparin therapy. Clinical monitoring of blood pressure is recommended.

Moderate:

Prematurity/Underweight in Infancy

Major:

Lovenox

The enoxaparin in Lovenox has a major potential interaction with Prematurity/Underweight in Infancy.

Some preparations (i.e., multiple-dose vials) of low molecular weight heparin (LMWH) contain benzyl alcohol as a preservative. Benzyl alcohol in bacteriostatic saline intravascular flush and endotracheal tube lavage solutions has been associated with fatalities and severe respiratory and metabolic complications in low-birthweight premature infants. Symptoms include a striking onset of gasping respiration, hypotension, bradycardia, and cardiovascular collapse. The manufacturers recommend that use of these products be avoided in all neonates whenever possible. Nevertheless, many experts feel that, in the absence of benzyl alcohol-free equivalents, the amount of the preservative present in these formulations should not necessarily preclude their use if they are clearly indicated. The American Academy of Pediatrics considers benzyl alcohol in low doses (such as when used as a preservative in some medications) to be safe for newborns. LMWHs are not approved for use in pediatric patients.

Renal Dysfunction

Major:

Lovenox

The enoxaparin in Lovenox has a major potential interaction with Renal Dysfunction.
