Most antacids contain oxygen and some sort of metal (calcium, sodium, potassium, aluminum, and magnesium are common). Additionally, most will contain hydrogen (in Mg(OH)2 and Al(OH)3), carbon (in CaCO3), or both (in NaHCO3 and KHCO3).

Antacids are medicine that counteract acidity. The different types of antacids are sodium antacids (Alka-seltzers), calcium antacids (Tums) and magnesium antacids (Maalox).
No, not all commercial antacids contain magnesium hydroxide. Antacids can contain different active ingredients such as calcium carbonate, aluminum hydroxide, or sodium bicarbonate in addition to magnesium hydroxide. It depends on the specific formulation and brand of the antacid.
Some drugs absorption depends on stomach acidity. If you use antacids, it might decrease (or increase) its absorption. Some antacids contain calcium that binds with some drugs (so will cancel its effect and absoprtion).
Some antacids, vaccines, and certain medications like aspirin, antidiarrheals, and antiperspirants may contain aluminum as an inactive ingredient. It is important to check the ingredient list or consult with a healthcare provider if you are concerned about aluminum content in a specific medicine.

Many antacids and calcium supplements contain calcium carbonate.
Antacids commonly contain ions such as calcium (Ca2+), magnesium (Mg2+), or aluminum (Al3+) to reduce acidity in the stomach. These ions bind to excess stomach acid, neutralizing it and reducing the overall acidity of the stomach.
Many cleaning products such as oven cleaner contain sodium hydroxide (NaOH). Also, antacids contain a base (base = alkaline) to reduce the acidity of the stomach.
Among the drugs that may interact with tetracyclines are: antacids, calcium supplements, medicines that contain iron.
Some common household products that contain sodium bicarbonate include baking soda, toothpaste, antacids, and some cleaning products.
