minor Known Drug Interaction
( 7.2 ) Cimetidine: Increased albendazole sulfoxide concentrations in bile and cystic fluid by about 2-fold in hydatid cyst patients. 7.3 Cimetidine Albendazole sulfoxide concentrations in bile and cystic fluid were increased (about 2-fold) in hydatid cyst patients treated with cimetidine (10 mg/kg/day) (n = 7) compared with albendazole (20 mg/kg/day) alone (n = 12).

Albendazole is a medicine that fights parasites. It is used to treat infections caused by tapeworms.
Cimetidine (Tagamet) reduces stomach acid. It is used to treat ulcers, heartburn, and other conditions where too much acid is produced.
Albendazole treats infections caused by tapeworms. It is used for neurocysticercosis, which is caused by pork tapeworm larvae in the brain. It also treats hydatid disease, caused by dog tapeworm larvae in the liver, lungs, and abdomen.
Cimetidine treats active duodenal ulcers for short periods. It can also be used long-term at a lower dose to prevent ulcers from returning. This medicine also treats active benign gastric ulcers for a short time. Additionally, it can help with erosive gastroesophageal reflux disease (GERD), which damages the esophagus.
Albendazole stops the tapeworms from growing and multiplying. It does this by blocking the worm's ability to use sugar (glucose). This eventually kills the parasite.
Cimetidine is an H2 receptor antagonist. This means it blocks histamine from attaching to certain cells in your stomach. By blocking histamine, cimetidine reduces the amount of acid your stomach makes.

Albendazole can cause bone marrow suppression, which can be fatal. Your doctor will check your blood counts before and during treatment. If your blood counts drop too low, you may need to stop taking albendazole. Albendazole can also harm an unborn baby, so women who can get pregnant should use birth control while taking it. If you are being treated for neurocysticercosis, you may experience seizures or other neurological problems. Your doctor may give you steroids and anti-seizure medicine to prevent these problems.
Reversible confusional states (like mental confusion, agitation, or hallucinations) have been reported, mostly in severely ill patients. These usually appear within 2-3 days of starting treatment and clear up within 3-4 days of stopping the drug.
Albendazole can harm an unborn baby. Women who can get pregnant should use effective birth control while taking albendazole and for one month after stopping the medicine. If you become pregnant while taking albendazole, tell your doctor right away.
Tell your doctor if you are pregnant or plan to become pregnant. The effects of cimetidine during pregnancy are not fully known. Talk to your doctor about the risks and benefits of taking cimetidine while breastfeeding.

How to Read This albendazole vs cimetidine Comparison
albendazole is classified in the Antiparasitic (Benzimidazole) drug class, while cimetidine sits within the H2 Receptor Antagonist class. Drugs from different classes work through distinct mechanisms, so a head-to-head comparison illustrates trade-offs rather than equivalence. Both drugs are split between OTC and prescription status, which affects access and supervision.
Adverse event totals above are pulled from the FDA's Adverse Event Reporting System (FAERS). For these top-ranked reactions alone, albendazole has 1,004 submissions while cimetidine has 3,947. Those figures reflect cumulative reporting volume, not per-patient risk, so older, widely dispensed drugs typically look worse on count alone. These two drugs have a known minor interaction flagged in FDA labeling, attributed to cimetidine interferes with how the body breaks down albendazole, which causes the drug levels to rise in certain body fluids.. Serious warnings, pregnancy guidance, and contraindications can differ even when indications overlap.
A table cannot represent individual circumstances. Data here is sourced from FDA Structured Product Labels (SPL) and FAERS, both of which update as manufacturers and clinicians submit new information. This registry does not provide medical, treatment, substitution, or medication-change directions for albendazole or cimetidine.
