Who should not use it?

Ibuprofen is not recommended for people who have previously experienced an allergic reaction to aspirin or other NSAIDs, or who have recently had or will soon undergo heart surgery.

It may also be unsuitable for those who:

• are using other NSAIDs or pain relief medication
• are using anticoagulants
• are receiving treatment for any serious condition
• have chickenpox or shingles
• have Crohn’s disease or ulcerative colitis
• have liver problems
• have high blood pressure
• have heart disease
• have kidney disease
• are aged over 60 years
• have taken a diuretic
• have repeated stomach problems, such as heartburn or abdominal pain
• have stomach ulcers
• have bleeding problems

Before taking ibuprofen, people who are already taking any type of medication should consult with a healthcare professional. The Food and Drug Administration (FDA) updated its warning about the increased risk of heart attack or stroke when taking ibuprofen in 2015. Side effects may occur during the first few weeks of using this medication. The risk increases with higher doses, long-term use, or if a person has a history of heart disease. The FDA urges people to be aware of this potential issue and to get immediate medical help if they notice any of the following symptoms: chest pain, breathing problems, sudden weakness in one side or part of the body, or slurred speech. If a person is unsure whether to take ibuprofen, they should speak to a doctor or licensed pharmacist.

When to stop using it

People should stop taking ibuprofen and consult a doctor if they experience any of the following symptoms:

• fainting or blood in the vomit or stool pain that worsens or lasts more than 10 days
• a fever that worsens or lasts for more than three days
• any new symptoms, such as swelling or a change in skin color in the area of pain

Allergic reactions

Some people might be allergic to ibuprofen's ingredients. Among the allergic symptoms are:

• hives, change in skin color, blistering, or a rash
• facial swelling
• wheezing and difficulty breathing
• shock

Anyone exhibiting these signs should stop taking the medication. In extreme circumstances, a person may experience anaphylactic shock and have trouble breathing. This is a medical emergency that needs to be treated right away.

Pregnancy and nursing

Ibuprofen should not be used after 20 weeks of pregnancy because it can cause low levels of amniotic fluid.

Before taking any medication during pregnancy or while nursing, a person should consult with a healthcare professional.

Is ibuprofen addictive?

Ibuprofen is not typically thought of by experts as a drug that will cause substance use disorder, but at least one case study suggests that it might.

It does not cause tolerance in the body, so a person won't require higher doses to achieve the same effect. When someone stops using it, there are no withdrawal symptoms either.

Ibuprofen and opioids, such as hydrocodone or oxycodone, are both present in some medications. Substance use disorder can result from the excessive use of these drugs.
