Advil is a brand name for ibuprofen, a nonsteroidal anti-inflammatory drug or NSAID. Ibuprofen works by reducing substances in your body that cause pain, inflammation, and fever. You can buy Advil without a prescription at most pharmacies and retail stores.

Millions of people rely on Advil for temporary relief from everyday aches and pains. When used as directed, it provides effective relief for minor to moderate discomfort. Always read the label carefully and follow dosing instructions to use Advil safely.

How it works
Advil blocks enzymes in your body called COX-1 and COX-2. These enzymes make prostaglandins, which are chemicals that trigger pain, swelling, and fever. By reducing prostaglandin production, Advil decreases inflammation and helps relieve pain signals throughout your body.
Unlike acetaminophen which mainly works in your brain, ibuprofen works at the actual site of pain and inflammation. This makes it especially effective for conditions involving swelling like arthritis or sports injuries. The fever-reducing effect happens when ibuprofen acts on the part of your brain that controls body temperature.

Dosage information
Adults and children 12 years and older typically take 200 to 400 mg every 4 to 6 hours as needed. Do not exceed 1,200 mg in 24 hours unless directed by a doctor. Children under 12 should use weight-based dosing as shown on the product label. Always use the lowest effective dose for the shortest time needed to control symptoms.
Side effects
- Upset stomach or nausea
- Heartburn
- Mild dizziness
- Gas or bloating
- Constipation or diarrhea
Stop taking Advil and seek medical help immediately if you experience chest pain, severe stomach pain, bloody or black stools, vomiting blood, sudden weight gain, swelling, or signs of an allergic reaction. Long-term use can increase risk of heart attack, stroke, and serious stomach bleeding.
Drug interactions
- Blood thinners like warfarin or aspirin can increase bleeding risk
- Other NSAIDs increase side effects when combined with ibuprofen
- Blood pressure medications may work less effectively
- Lithium levels can increase when taken with ibuprofen
- Methotrexate toxicity risk increases with NSAID use
- Alcohol increases stomach bleeding risk
- Corticosteroids like prednisone raise gastrointestinal bleeding risk
- SSRI antidepressants may increase bleeding risk
Blood test monitoring
Regular Advil use can affect your kidney function over time. If you take ibuprofen frequently or for extended periods, you should monitor your creatinine and eGFR levels through blood testing. Creatinine is a waste product that healthy kidneys filter from your blood. The eGFR or estimated glomerular filtration rate tells you how well your kidneys are working. Rite Aid offers blood testing that measures these kidney markers along with 200 other biomarkers. Testing twice yearly helps catch any kidney changes early so you can adjust your pain management approach with your doctor.

Frequently asked questions
Yes, Advil is available over the counter at Rite Aid and most pharmacies. You do not need a prescription to purchase it. However, you should talk to your doctor before using Advil regularly or for more than 10 days. Your pharmacist can also answer questions about proper use.
Advil typically starts relieving pain within 30 to 60 minutes after you take it. Liquid gels may work slightly faster than regular tablets because they dissolve more quickly. The pain relief usually lasts 4 to 6 hours depending on your dose and individual response.
Adults should not take more than 1,200 mg of ibuprofen in 24 hours without doctor guidance. For prescription-strength use, doctors may recommend up to 3,200 mg daily in divided doses. Taking more than recommended increases your risk of serious side effects including stomach bleeding and kidney damage.
You can take Advil with or without food. However, taking it with food or milk may help reduce stomach upset. If you experience heartburn or nausea, try taking your dose with a meal or snack. Drink a full glass of water with each dose.
NSAIDs like ibuprofen can reduce blood flow to your kidneys over time. This can lead to decreased kidney function, especially with long-term use. Monitoring creatinine and eGFR levels helps detect early kidney changes before they become serious. Regular blood testing allows you and your doctor to adjust your treatment if needed.
Daily Advil use requires medical supervision due to increased risks of stomach bleeding, kidney damage, and heart problems. If you need pain relief for more than 10 days, talk to your doctor about safer long-term options. Your doctor can help you weigh the benefits against the risks for your specific situation.
NSAIDs like Advil can raise blood pressure and make blood pressure medications less effective. If you have high blood pressure, ask your doctor before using ibuprofen. Your doctor may recommend acetaminophen as a safer alternative. If you do take Advil, monitor your blood pressure regularly.
Advil contains ibuprofen, an NSAID that reduces inflammation, pain, and fever. Tylenol contains acetaminophen, which relieves pain and fever but does not reduce inflammation. Advil works better for inflammatory conditions like arthritis or muscle injuries. Tylenol is often safer for people with stomach issues or kidney problems.
If you use Advil daily or several times per week, consider testing your kidney function every 6 months. Rite Aid offers blood testing that checks creatinine, eGFR, and over 200 other biomarkers twice yearly. Regular monitoring helps you catch potential problems early and make informed decisions about your pain management.
If you take more than the recommended dose, call Poison Control at 1-800-222-1222 or seek emergency care immediately. Symptoms of ibuprofen overdose include severe stomach pain, vomiting, drowsiness, and breathing problems. Do not wait for symptoms to appear if you have taken a large overdose.
