Ibuprofen is one of the most widely used painkillers in the world. It belongs to a group of drugs called nonsteroidal anti-inflammatory drugs (NSAIDs), which work by blocking the production of chemicals called prostaglandins that cause pain, inflammation and fever in the body. Ibuprofen can help relieve various types of pain, such as headaches, menstrual cramps, toothaches, arthritis and injuries. It can also reduce fever and ease the symptoms of colds and flu.
But how much do you know about ibuprofen? How does it work, how should you use it, what are the possible side effects and interactions, and who should avoid it? In this blog post, we will answer some of the most frequently asked questions about ibuprofen and provide you with useful information to help you use this drug safely and effectively.
What is ibuprofen and how does it work?
Ibuprofen is a synthetic drug that was discovered in the 1950s by a British chemist named Stewart Adams. It was first marketed in 1969 under the brand name Brufen. Today, ibuprofen is available in various forms, such as tablets, capsules, liquids, gels and creams. It can be bought over-the-counter (without a prescription) or prescribed by a doctor for certain conditions.
Ibuprofen works by inhibiting an enzyme called cyclooxygenase (COX), which is responsible for making prostaglandins from fatty acids. Prostaglandins are hormone-like substances that play a role in many bodily functions, such as blood clotting, blood pressure regulation, kidney function and digestion. However, they also mediate pain, inflammation and fever by sensitizing nerve endings and dilating blood vessels.
By blocking COX, ibuprofen reduces the amount of prostaglandins in the body and thus relieves pain, inflammation and fever. However, ibuprofen also affects other types of prostaglandins that have beneficial effects on the stomach lining, blood flow to the kidneys and platelet aggregation. This is why ibuprofen can cause side effects such as stomach ulcers, kidney damage and bleeding problems.
How should you use ibuprofen?
The dose and frequency of ibuprofen depend on your age, weight, medical condition and response to treatment. You should always follow the instructions on the label or the prescription from your doctor. Do not take more than the recommended dose or for longer than advised.
The usual adult dose of ibuprofen for pain or fever is 200 to 400 mg every four to six hours as needed. The maximum daily dose is 1200 mg. For children aged 6 months to 12 years, the dose is based on their weight and is usually given as a liquid suspension. The usual dose is 5 to 10 mg per kg of body weight every six to eight hours as needed. The maximum daily dose is 40 mg per kg of body weight.
You can take ibuprofen with or without food, but taking it with food or milk may help prevent stomach upset. Do not crush, chew or break the tablets or capsules; swallow them whole with a glass of water. If you are using a liquid form of ibuprofen, shake the bottle well before each use and measure the dose carefully with a dosing syringe or spoon. Do not use a household spoon, as you may not get the correct dose.
If you are using a topical form of ibuprofen, such as a gel or cream, apply a thin layer to the affected area and massage gently until absorbed. Do not cover the area with a bandage or dressing unless instructed by your doctor. Wash your hands after applying the product and avoid contact with your eyes, mouth and mucous membranes.
If you miss a dose of ibuprofen, take it as soon as you remember, unless it is almost time for your next dose. In that case, skip the missed dose and continue with your regular schedule. Do not double the dose to make up for the missed one.
If you take too much ibuprofen, seek medical attention immediately. Symptoms of overdose may include nausea, vomiting, stomach pain, drowsiness, dizziness, headache, ringing in the ears, blurred vision, confusion, seizures, low blood pressure, slow or irregular heartbeat, difficulty breathing and coma.
What are the possible side effects and interactions of ibuprofen?
Ibuprofen is generally well tolerated by most people, but it can cause some side effects in some cases. The most common side effects are:
- Stomach pain, nausea, vomiting, indigestion, heartburn, diarrhea or constipation
- Headache, dizziness or drowsiness
- Rash, itching or hives
- Fluid retention or swelling in the ankles, feet or hands
Most of these side effects are mild and temporary and can be reduced by taking ibuprofen with food or milk. However, some side effects can be serious and require medical attention. These include:
- Stomach ulcers or bleeding, which may cause black or bloody stools, vomiting blood or coffee-ground-like material, severe stomach pain or signs of anemia (such as pale skin, weakness or fatigue)
- Kidney problems, which may cause changes in urine output or color, swelling in the legs or feet, shortness of breath or signs of electrolyte imbalance (such as muscle cramps, confusion or irregular heartbeat)
- Liver problems, which may cause yellowing of the skin or eyes (jaundice), dark urine, nausea, loss of appetite or signs of liver failure (such as bleeding, bruising or infection)
- Allergic reactions, which may cause swelling of the face, lips, tongue or throat; difficulty breathing; wheezing; chest tightness; rash; itching; hives; blisters; fever; joint pain; or anaphylaxis (a severe and potentially life-threatening reaction that requires immediate medical attention)
- Blood problems, which may cause easy bruising or bleeding; nosebleeds; gum bleeding; red or purple spots on the skin; sore throat; fever; infections; or signs of bone marrow suppression (such as fatigue, weakness or pale skin)
- Heart problems, which may cause chest pain; shortness of breath; swelling in the legs or feet; irregular heartbeat; high blood pressure; stroke; heart attack; or heart failure
- Nervous system problems, which may cause confusion; hallucinations; depression; anxiety; insomnia; agitation; mood changes; memory loss; seizures; vision problems; hearing problems; tinnitus (ringing in the ears); numbness; tingling; weakness; or paralysis
If you experience any of these side effects while taking ibuprofen, stop taking it and contact your doctor right away.
Ibuprofen can also interact with other drugs and affect their effectiveness or increase their side effects. Some of the drugs that can interact with ibuprofen are:
- Aspirin and other NSAIDs (such as naproxen), which can increase the risk of stomach ulcers and bleeding
- Anticoagulants (blood thinners) such as warfarin and heparin), which can increase the risk of bleeding
- Corticosteroids (such as prednisone), which can increase the risk of stomach ulcers and bleeding
- Diuretics (water pills) such as furosemide and hydrochlorothiazide), which can reduce their effectiveness and increase the risk of kidney problems
- ACE inhibitors (such as lisinopril and enalapril), angiotensin II receptor blockers (such as losartan and valsartan) and beta blockers (such as metoprolol and atenolol), which can reduce their effectiveness and increase the risk of kidney problems and high potassium levels
- Lithium (a mood stabilizer), which can increase its levels and toxicity
- Methotrexate (a chemotherapy drug), which can increase its levels and toxicity
- Cyclosporine (an immunosuppressant drug), which can increase its levels and toxicity
- Digoxin (a heart drug), which can increase its levels and toxicity
- Antidepressants (such as fluoxetine and sertraline), which can increase the risk of bleeding and affect the mood
- Anticonvulsants (such as phenytoin and carbamazepine), which can affect their levels and effectiveness
- Antibiotics (such as ciprofloxacin and rifampin), which can affect their levels and effectiveness
- Antifungals (such as ketoconazole and fluconazole), which can affect their levels and effectiveness
- Herbal supplements (such as ginkgo biloba and garlic), which can increase the risk of bleeding
This is not a complete list of all the possible interactions of ibuprofen. Before taking ibuprofen, tell your doctor about all the medications, supplements and herbal products you are using or planning to use. Do not start, stop or change the dose of any drug without your doctor’s approval.
Who should avoid ibuprofen?
Ibuprofen is not suitable for everyone. Some people may have an allergy or intolerance to ibuprofen or any of its ingredients. Symptoms of an allergic reaction may include rash, itching, hives, swelling, difficulty breathing or anaphylaxis. If you have ever had an allergic reaction to ibuprofen or any other NSAID, do not take ibuprofen.
Some medical conditions may also make ibuprofen unsafe or ineffective for you. You should not take ibuprofen if you have:
- A history of stomach ulcers, bleeding or perforation
- A history of bleeding disorders or blood clotting problems
- A history of heart problems, such as angina, heart attack, heart failure or stroke
- A history of high blood pressure or kidney problems
- A history of liver problems or hepatitis
- A history of asthma, rhinitis or nasal polyps
- A history of lupus or other autoimmune diseases
