The Pharmacist’s Take By · Clinical pharmacist · Written

Aluminum hydroxide is an older, familiar over-the-counter antacid that neutralizes stomach acid to relieve heartburn, acid indigestion and sour stomach, and it also appears in skin ointments that dry the oozing and weeping of poison ivy, oak and sumac rashes; on the U.S. market since about 1983, it is available generically from many makers. Most people tolerate it well, and constipation is the side effect most often noticed with the liquid. Pay attention to how long you have been using it, and stop and see a doctor if symptoms get worse, last more than 7 days, or clear up and then come back within a few days.

Clinical pearls

  • Shake the liquid well and take it after meals and at bedtime, with a sip of water afterward if needed.
  • Do not take the maximum amount on the label for more than 2 weeks.
  • The poison ivy ointments are for skin only, so keep them out of the eyes and call Poison Control if swallowed.
  • Ask a doctor before giving the liquid to children under 12, or using ProCure DryDrox on babies under 6 months.

Aluminum Hydroxide: pharmacist answers to common questions

Quick, plain-English answers to the questions patients ask most about Aluminum Hydroxide — the kind of thing our pharmacy team would talk through with you at the counter.

What is Aluminum Hydroxide used for?

▾
It depends on the product. The oral liquid relieves heartburn, acid indigestion and sour stomach. The topical products, ProCure DryDrox and Claravie, dry the oozing and weeping of poison ivy, oak and sumac.

How do I take the oral liquid?

▾
Shake it well first. Take it after meals and at bedtime, with a sip of water if you need it. Don't use the maximum amount for more than 2 weeks, and follow the label and your prescriber.

How do I use the skin products?

▾
ProCure DryDrox and Claravie are applied to the skin as needed. They are for external use only, so keep them out of your eyes.

Can my child use it?

▾
Ask a doctor first. That applies to children under 12 with the oral liquid and to babies under 6 months with ProCure DryDrox.

When should I stop and call a doctor?

▾
Stop and check in with a doctor if things get worse, last more than 7 days, or clear up and come back within a few days. If someone swallows the product by accident, call Poison Control or a physician right away.

Is Aluminum Hydroxide available over the counter?

▾
Yes. The Aluminum Hydroxide products listed with the FDA are sold over the counter, without a prescription (the oral solution and topical cream, ointment or gel forms). Follow the package directions. Your pharmacist can tell you which product is right for you.

When was Aluminum Hydroxide first available?

▾
The earliest FDA record we hold for Aluminum Hydroxide is from 1983: its first approval in Drugs@FDA or its earliest product listing in the NDC Directory, whichever is older. Many older medicines were in use before their first formal FDA approval, so this is the earliest date on record, not necessarily when Aluminum Hydroxide was first used.

Who makes Aluminum Hydroxide?

▾
4 companies currently list Aluminum Hydroxide products in the FDA's NDC Directory, including Atlantic Biologicals Corp., Gentell LLC, Rugby Laboratories. That count includes repackagers and distributors as well as manufacturers (companies that sell only the raw ingredient are not counted), so fewer companies actually make it; the label on your bottle names the one that supplied yours.

How widely Aluminum Hydroxide is used (Medicaid data)

A general measure of how commonly Aluminum Hydroxide is prescribed, based on Medicaid — one of the largest public drug programs. The figure below is prescriptions filled in Q1–Q4 2025, summed across every form and brand of the drug.

Think of this as a proxy for how widely Aluminum Hydroxide is used, drawn from freely available public data. Medicaid is just one program — these numbers don’t include Medicare, other government coverage, or commercial and cash-pay prescriptions, so real-world use is higher than what’s shown here.

Shares are of the Medicaid prescriptions shown here. Product grouping follows RxNorm (the National Library of Medicine’s drug terminology), so “one product” means one strength & dosage form regardless of manufacturer. Dollar figures are gross Medicaid reimbursement before mandatory rebates — rebates (often large, especially for brand-name drugs) are confidential, so actual net cost to Medicaid is lower than shown.
