What is allopurinol 100 mg used for?
Allopurinol 100 mg is a prescription medicine used to lower uric acid levels in the body. It’s commonly prescribed to help prevent gout attacks and to treat certain conditions caused by high uric acid (hyperuricemia), such as gout.
How does allopurinol 100 mg work?
Allopurinol reduces uric acid production by inhibiting xanthine oxidase, the enzyme the body uses to make uric acid. Lower uric acid can reduce the risk of gout flares and help dissolve or prevent urate crystal build-up over time.
How should allopurinol 100 mg be taken?
Dosing is individualized based on the reason you’re taking it and your kidney function. Many people start on a lower dose (like 100 mg) and clinicians may adjust upward gradually.
Key practical points patients typically follow include:
- Take it once daily unless your prescriber directs otherwise.
- Do not stop it suddenly without medical advice.
- Expect gout flare risk can change early in treatment, so prescribers sometimes use additional flare prevention during dose changes.
What side effects are associated with allopurinol?
Common side effects can include nausea, diarrhea, and skin rash. Serious skin reactions can occur with allopurinol and need urgent medical attention. If you develop blistering/peeling rash, facial swelling, trouble breathing, or widespread rash with fever, seek emergency care.
Who should be careful with allopurinol (kidney disease and drug interactions)?
Allopurinol dosing often needs adjustment in people with kidney problems. It also has important drug interactions (for example, with some blood thinners and other medicines that affect uric acid or immune activity). The safest way to confirm interaction risk is to check your full medication list with your pharmacist or prescriber.
Is allopurinol 100 mg a brand or generic?
Allopurinol is widely available as a generic medicine, and 100 mg tablets are a common strength.
What happens if you miss a dose?
If you miss a dose, take it when you remember unless it’s close to the next scheduled dose. Do not take double doses without medical advice.
