Oxygen toxicity.
Vitamin toxicity is a condition in which a person develops symptoms as side effects from taking massive doses of vitamins.
Oxygen is not addictive and causes no side effects when used as prescribed.
Pulmonary Oxygen Toxicity (PO) and Central Nervous System Toxicity (CNS)
Although extensive research has not been conducted, there have been no reported side effects or toxicity associated with lycopene intake.
Complications from oxygen therapy used in appropriate situations are infrequent. Respiratory depression, oxygen toxicity, and absorption atelectasis are the most serious complications of oxygen overuse.
Abnormally slow breathing is a symptom of oxygen toxicity
Terramycin has several side effects. These include various gastrointestinal problems, skin rashes, photosensitivity, hypersensitivity, renal toxicity, and anemia.
No known side effects except possible allergic reaction. High doses over extended periods of time may cause kidney or liver toxicity.
Addiction
Pulmonary oxygen toxicity is caused by divers exposing themselves to elevated partial pressures of oxygen for long periods of time, and is primarily a concern for technical divers who decompress on oxygen. Pulmonary oxygen toxicity causes a burning sensation in the trachea, coughing, shortness of breath, and eventually lung failure.
However, interferon alpha 2a has high toxicity and patients may not tolerate the side effects.
