The veteran gout drug, with a second career: making certain antibiotics more effective by keeping them in the body longer. It prevents gout attacks; it does not treat one in progress.
What does it treat?
Chronic gout and gouty arthritis - and, paired with certain antibiotics, higher and longer antibiotic levels.
How do you take it?
Twice a day for gout; four times a day when boosting antibiotics - exactly as directed. The honest warning: attacks can get more frequent in the first 6 to 12 months as the uric acid moves - your doctor may add colchicine to blunt this; a flare is not a reason to stop. Drink plenty of water daily - the drug pushes uric acid through the kidneys, and hydration is how stones stay away. Missed dose: take it when you remember unless the next one is close; never double up.
Side effects to know
Common: headache, upset stomach, vomiting, loss of appetite, and dizziness.
Serious - call your doctor immediately: severe skin rash, difficulty breathing or swallowing, and unusual bleeding or bruising.
Who should not take it?
Not during an active gout attack - it starts after the attack settles. Flag kidney stones or kidney disease, blood disorders, ulcer history, and the genetic G6PD deficiency. It changes how many drugs clear - aspirin in particular cancels its effect, so no aspirin products without your doctor's say. If you become pregnant, call your doctor.
When is it an emergency?
In an emergency, call 911Trouble breathing or swallowing, a severe spreading rash, or bleeding that will not stop is a 911 call. For an overdose, call Poison Control at 1-800-222-1222. Pymander's escalation routing is built and tested specifically for this class of decision; see the safety architecture working paper.

Common questions
Why did my attacks get worse before they got better?
The mobilization effect: as uric acid leaves the tissues through the kidneys, attacks can actually increase for the first 6 to 12 months - MedlinePlus states it plainly - before the drug wins and attacks stop forming. Colchicine is often prescribed alongside for exactly this window. The rules: never start it during an attack, and never stop it for one.
Why can't I take aspirin with it?
Direct cancellation: aspirin blocks probenecid's uric-acid-flushing effect at the kidney - the two work against each other. The catch is aspirin hiding in combination products: cold remedies, pain relievers, some stomach medicines. The pharmacist label-check is the habit, and any new over-the-counter product gets the "I take probenecid" conversation.
Why all the water?
The drug routes uric acid through the kidneys into the urine - concentrated uric acid in a dry urinary tract is how kidney stones form. Generous daily water keeps it diluted and moving. Kidney stone history is a prescribing factor for the same reason. Think of the water as part of the dose.
How does it make antibiotics work better?
Same kidney trick, aimed at the drug instead: probenecid blocks the renal excretion of certain antibiotics - the body passes them into urine more slowly, so levels stay higher and longer. That is why the antibiotic course sometimes comes with four-times-daily probenecid. It also means it can raise levels of other medications - the full medication list stays current with your doctor and pharmacist.
How is this different from allopurinol or febuxostat?
Two strategies against the same enemy: allopurinol and febuxostat cut uric-acid production; probenecid increases its removal. Production-cutting suits most people; removal works when the kidneys are healthy and stones are not in the picture. Which side your prescription is on says something about your kidneys and your history - worth knowing.
What happens if I miss a dose of probenecid?
Take it as soon as you remember, unless it is almost time for the next one - then skip it and never double up. Doubling increases stomach upset without speeding anything. The twice-daily anchor with breakfast and dinner is the rhythm that holds.
