Interactions between ConRx AR and Mefloquine

Mefloquine has a major potential interaction with Depression.

The use of mefloquine for malaria prophylaxis is contraindicated in patients with active depression, a recent history of depression, generalized anxiety disorder, psychosis, schizophrenia, or other major psychiatric disorders. Mefloquine may cause psychiatric symptoms in some patients, including agitation, anxiety, depression, mood changes, panic attacks, paranoia, confusion, hallucinations, aggression, and psychotic behavior. Occasionally, these symptoms have been reported to continue long after mefloquine has been withdrawn due to its long half-life. Rare cases of suicidal ideation and suicide have occurred during mefloquine use, although a causal relationship has not been established. Therapy with mefloquine should be administered cautiously in patients with a previous history of depression. Psychiatric symptoms that occur during prophylactic use such as acute anxiety, depression, restlessness, or confusion should be considered prodromal to a more serious event, and the drug must be discontinued and an alternative medication substituted.

The magnesium hydroxide in ConRx AR has a major potential interaction with Gastrointestinal Obstruction.

The use of laxatives is contraindicated in patients with intestinal obstruction disorders. Patients with intestinal obstruction disorders may need their underlying condition treated to correct the constipation. Some laxatives require reduction in the colon to their active form to be effective which may be a problem in patients with intestinal obstruction.

Mefloquine has a moderate potential interaction with Heart Disease.

Mefloquine is a myocardial depressant. Animal studies with parenteral mefloquine indicate that the drug possesses 20% of the antifibrillatory action of quinidine and produces 50% of the increase in the PR interval reported with quinine. The effect of mefloquine on the compromised cardiovascular system has not been evaluated. However, transient and asymptomatic ECG alterations have been reported during the use of mefloquine, including sinus bradycardia, sinus arrhythmia, first-degree AV block, prolongation of the QTc interval, and abnormal T waves. In postmarketing use, hypotension, hypertension, flushing, syncope, chest pain, tachycardia, palpitation, bradycardia, irregular pulse, extrasystoles, AV block, and other transient cardiac conduction alterations have been reported rarely. Therapy with mefloquine should be administered cautiously in patients with cardiac disease and only if potential benefits justify the risks.

The magnesium hydroxide in ConRx AR has a major potential interaction with Inflammatory Bowel Disease.

The use of laxatives is contraindicated in patients with inflammatory bowel disease. Patients with inflammatory bowel disease may experience colonic perforation with use of stimulant laxatives.

The aluminum hydroxide in ConRx AR has a major potential interaction with Intestinal Obstruction.

Aluminum containing antacids may produce constipation, which may lead to intestinal obstruction. Osteomalacia and hypophosphatemia may be produced in patients with renal dysfunction who are not receiving dialysis. Patients with renal dysfunction, intestinal obstruction, osteomalacia, or hypophosphatemia should use antacids with low or no aluminum content.

Mefloquine has a moderate potential interaction with Liver Disease.

Mefloquine is primarily metabolized by the liver. Patients with liver disease may be at greater risk for adverse effects from mefloquine due to decreased drug clearance. Therapy with mefloquine should be administered cautiously in patients with liver disease. Periodic evaluation of hepatic function should be performed during prolonged therapy.

Mefloquine has a major potential interaction with Neurosis.

The use of mefloquine for malaria prophylaxis is contraindicated in patients with active depression, a recent history of depression, generalized anxiety disorder, psychosis, schizophrenia, or other major psychiatric disorders. Mefloquine may cause psychiatric symptoms in some patients, including agitation, anxiety, depression, mood changes, panic attacks, paranoia, confusion, hallucinations, aggression, and psychotic behavior. Occasionally, these symptoms have been reported to continue long after mefloquine has been withdrawn due to its long half-life. Rare cases of suicidal ideation and suicide have occurred during mefloquine use, although a causal relationship has not been established. Therapy with mefloquine should be administered cautiously in patients with a previous history of depression. Psychiatric symptoms that occur during prophylactic use such as acute anxiety, depression, restlessness, or confusion should be considered prodromal to a more serious event, and the drug must be discontinued and an alternative medication substituted.

The aluminum hydroxide in ConRx AR has a major potential interaction with Phosphate Imbalance.

Aluminum containing antacids may produce constipation, which may lead to intestinal obstruction. Osteomalacia and hypophosphatemia may be produced in patients with renal dysfunction who are not receiving dialysis. Patients with renal dysfunction, intestinal obstruction, osteomalacia, or hypophosphatemia should use antacids with low or no aluminum content.

Mefloquine has a major potential interaction with Psychiatric Disorders.

The use of mefloquine for malaria prophylaxis is contraindicated in patients with active depression, a recent history of depression, generalized anxiety disorder, psychosis, schizophrenia, or other major psychiatric disorders. Mefloquine may cause psychiatric symptoms in some patients, including agitation, anxiety, depression, mood changes, panic attacks, paranoia, confusion, hallucinations, aggression, and psychotic behavior.

Rare cases of suicidal ideation and suicide have occurred during mefloquine use, although a causal relationship has not been established. Therapy with mefloquine should be administered cautiously in patients with a previous history of depression. Psychiatric symptoms that occur during prophylactic use such as acute anxiety, depression, restlessness, or confusion should be considered prodromal to a more serious event, and the drug must be discontinued and an alternative medication substituted.

Mefloquine has a major potential interaction with Psychosis.

The use of mefloquine for malaria prophylaxis is contraindicated in patients with active depression, a recent history of depression, generalized anxiety disorder, psychosis, schizophrenia, or other major psychiatric disorders. Mefloquine may cause psychiatric symptoms in some patients, including agitation, anxiety, depression, mood changes, panic attacks, paranoia, confusion, hallucinations, aggression, and psychotic behavior. Occasionally, these symptoms have been reported to continue long after mefloquine has been withdrawn due to its long half-life. Rare cases of suicidal ideation and suicide have occurred during mefloquine use, although a causal relationship has not been established.

The aluminum hydroxide in ConRx AR has a major potential interaction with Renal Dysfunction.

Aluminum containing antacids may produce constipation, which may lead to intestinal obstruction. Osteomalacia and hypophosphatemia may be produced in patients with renal dysfunction who are not receiving dialysis. Patients with renal dysfunction, intestinal obstruction, osteomalacia, or hypophosphatemia should use antacids with low or no aluminum content.

The magnesium hydroxide in ConRx AR has a major potential interaction with Renal Dysfunction.

Magnesium is eliminated by the kidney. The serum concentration of magnesium is increased in patients with renal impairment. Magnesium toxicity includes CNS depression, muscular paralysis, respiratory depression, hypotension and prolonged cardiac conduction time. Disappearance of the patellar reflex is a useful clinical sign of magnesium intoxication. Therapy with magnesium should be administered cautiously and dosages should be modified in patients with compromised renal function. Clinical monitoring of serum magnesium levels is recommended.

Mefloquine has a major potential interaction with Seizures.

The use of mefloquine for malaria prophylaxis is contraindicated in patients with a history of seizures. Mefloquine can increase the risk of convulsions in patients with epilepsy and may lower the plasma levels of some anticonvulsant medications. Therefore, it should only be prescribed for curative treatment of malaria in such patients and only if there are compelling medical reasons for its use.
