1. What is Maalox and what is it used for

Maalox is a combination medicine with local anti-acid action, which neutralizes excess stomach acid, protects and soothes the stomach and duodenum mucosa. It does not cause excessive neutralization of stomach contents and secondary stimulation of acid secretion.

Maalox is indicated for the symptomatic treatment of upper gastrointestinal disorders associated with hyperacidity:

  • gastritis,
  • gastroesophageal reflux disease (GERD),
  • heartburn and acid regurgitation due to hyperacidity, and as an adjunct in the treatment of:
  • duodenal ulcer disease,
  • gastric ulcer disease.

2. Important information before taking Maalox

  • if you are allergic to aluminum hydroxide, magnesium hydroxide, or any of the other ingredients of this medicine (listed in section 6),
  • if you have severe kidney impairment (see Warnings and precautions).

Be cautious when taking Maalox:

  • in patients with kidney impairment or those undergoing hemodialysis,
  • in children under 6 years of age, consult a doctor before administration,
  • in elderly patients,
  • when taking the medicine for more than 2 weeks or in patients at risk of hypophosphatemia (low phosphate levels in the blood), consult a doctor.

Children

The use of magnesium hydroxide in young children may lead to hypermagnesemia, especially if they have kidney function disorders or dehydration.

Maalox and other medicines

Tell your doctor or pharmacist about all medicines you are taking or have recently taken, as well as any medicines you plan to take, as Maalox may affect the action of some medicines or some medicines may affect the action of Maalox.

In particular:

  • medicines used to treat heart conditions, such as digoxin, quinidine, metoprolol, atenolol, and propranolol
  • medicines used to treat anemia, such as iron salts

  • medicines used to treat malaria, such as chloroquine
  • medicines used to treat certain bone disorders, such as bisphosphonates
  • medicines used to treat allergic reactions, inflammatory reactions, or abnormal immune reactions, such as glucocorticoids
  • medicines used to treat kidney disorders, such as citrates
  • medicines used to treat tuberculosis, such as ethambutol, isoniazid
  • medicines used to treat infections, such as fluoroquinolones, lincosamides, ketoconazole, cyclines, cephalosporins (cefpodoxime and cefdinir), dolutegravir, elvitegravir, raltegravir (as potassium salt), and combination antiviral therapy including tenofovir alafenamide/emtricitabine/bictegravir (as sodium salt), rilpivirine.
  • medicines used to treat mental illnesses (psychoses), such as phenothiazines, neuroleptics

As a precaution, plan to take any oral medicine and antacid at least 2 hours apart (for fluoroquinolones, more than 4 hours apart).

Concomitant use of Maalox with:

  • quinidine (used to treat heart rhythm disorders and prevent them) may increase quinidine levels in the blood and lead to its overdose
  • polystyrene sulfonate (used to treat hyperkalemia - high potassium levels in the blood) reduces the antacid effect of Maalox. Maalox reduces the effectiveness of polystyrene sulfonate. Concomitant use of these medicines increases the risk of metabolic alkalosis in patients with kidney impairment and intestinal obstruction.

Magnesium Hydroxide and other medicines

Magnesium hydroxide may affect the action of some medicines or some medicines may affect the effectiveness of magnesium hydroxide. Tell your doctor or pharmacist if you are taking:
