Small white pills imprinted with "IP 466" are a form of ibuprofen, which is a non-steroidal anti-inflammatory drug, according to the National Library of Medicine. Most over-the-counter ibuprofen pills contain a 200-milligram dose, but IP 466 pills contain an 800-milligram dose and should only be prescribed by your doctor.
While ibuprofen is generally safe to consume, there are several side effects, including nausea, respiratory issues, dizziness, constipation and flatus that may occur. If you take ibuprofen and experience negative side effects, it's best to consult your doctor.
Nausea and Abdominal Pain
At any dose, including 800 milligrams, IP 466 pills can cause some uncomfortable side effects. Use of ibuprofen may induce nausea or abdominal pain, according to the Mayo Clinic.
Nausea may also occur along with other gastrointestinal side effects, such as heartburn, belching or an acidic stomach, according to the Mayo Clinic. The IP 466 pills also may induce vomiting.
You also may develop problems with your breathing while taking ibuprofen pills, according to the Mayo Clinic. Your breathing may make a rattling or other noisy sound, or you may experience shortness of breath.
You also may experience trouble breathing when you exert yourself, or even at rest. If you experience breathing issues, it's best to consult a doctor immediately.
Dizziness is a common side effect of ibuprofen that may include a sense of disequilibrium, according to the Mayo Clinic. This means you may feel light-headed as you stand or turn your head. This common side effect can be bothersome but also potentially dangerous.
If you're experiencing dizziness, you should avoid driving and discuss this symptom with your medical practitioner.
Constipation and Diarrhea
You may also experience digestive issues and difficulty passing a bowel movement, or your stool may have a hard consistency, according to the Mayo Clinic.
On the other hand, while some may experience constipation as a side effect, others may struggle with diarrhea. These symptoms can be uncomfortable but can be alleviated through certain medications. Talk to your doctor about the options available.
You may also experience flatulence as a result of taking this drug, according to the Mayo Clinic. While this may not be one of the more serious IP 466 side effects, it can feel uncomfortable and cause bloating.
Flatulence may also indicate the presence of a more serious side effect like constipation or diarrhea. If other symptoms occur, consult a medical professional.
