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.

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.
How commonly is Aluminum Hydroxide prescribed? Of the 1,601 medications we measure, Aluminum Hydroxide ranks #1,311 by Medicaid prescriptions — more than 18% of them.
Utilization by Aluminum Hydroxide product
Pick a product to see its own Medicaid numbers. Each chip is one clinical product — a specific strength & dosage form as defined by RxNorm — with brand-name and generic versions combined.

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.

A representative set of FDA-listed product records for Aluminum Hydroxide — across manufacturers, strengths, and dosage forms, grouped by form with each product’s manufacturer and how the FDA approved it. The same medicine may be made and packaged by different companies, so a single drug can have many directory entries. (It’s also why a refill can look different — a new shape, color, or box — even though it contains the same medication.)

Aluminum Hydroxide side effects reported to the FDA (FAERS)
After a medicine reaches the market, patients, doctors and drugmakers can send the FDA reports of problems they think may be linked to it. Here’s what’s been reported for Aluminum Hydroxide — a signal of what to watch for, not proof the drug caused it.
Source: openFDA, from the FDA Adverse Event Reporting System (FAERS). These are voluntary reports — they don’t prove the drug caused the effect, and counts reflect how often something was reported, not how often it actually happens. Reports also often name the very problem the medicine is taken for — a common reason to file one is that the drug didn’t help — so for a pain reliever you may see “pain” high on the list; that points to why the report was filed, not to the drug causing the symptom. This counts every report that lists Aluminum Hydroxide in any role, so the total runs higher than the FDA’s official dashboard, which counts only cases where the drug is the suspect. For the authoritative figures, see the FDA FAERS Public Dashboard. Always talk to your pharmacist or doctor.
