See combination drugs.Nursing implicationsNursing assessment- Antacid: Assess for heartburn and indigestion as well as location, duration, character, and precipitating factors of gastric pain.
- Lab Test Considerations: Monitor serum phosphate, potassium, and calcium levels periodically during chronic use. May cause ↑ serum calcium and ↓ serum phosphate concentrations.
Potential Nursing DiagnosesAcute pain (Indications)
Implementation- Magnesium and aluminum are combined as antacids to balance the constipating effects of aluminum with the laxative effects of magnesium.
- Oral: To prevent tablets from entering small intestine in undissolved form, they must be chewed thoroughly before swallowing. Follow with at least ½ glass of water.
- Shake suspensions well before administration.
- For an antacid effect, administer 1–3 hr after meals and at bedtime.
Patient/Family Teaching- Caution patient to consult health care professional before taking antacids for more than 2 wk if problem is recurring, if relief is not obtained, or if symptoms of gastric bleeding (black, tarry stools; coffee-ground emesis) occur.
- Advise patient not to take this medication within 2 hr of taking other medications.
- Pediatric: Aluminum- or magnesium-containing medicines can cause serious side effects in children, especially when given to children with renal disease or dehydration. Advise parents or caregivers not to administer OTC antacids to children without consulting health care professional.
