Final answer:
Drug absorption can lead to a range of side effects such as constipation, nausea, pupil constriction, and respiratory depression. More severe effects can impact motor coordination, breathing, and heart function. The type and severity of side effects vary by individual and medication.
Step-by-step explanation:
Drug absorption can lead to various side effects which may include constipation, nausea, pupil constriction, and respiratory depression. These side effects can be experienced even when drugs are taken as prescribed. More broadly speaking, some drugs can also cause symptoms such as diarrhea, abdominal pain, headache, cough, chills, muscle pain, fever, and conjunctivitis. Furthermore, taking medications like opioids may lead to more severe reactions that affect motor coordination, breathing, and heart function. Antidepressants may contribute to weight gain, fatigue, dizziness, and other effects, with the severity and occurrence of these symptoms varying among patients.
It is also important to note that substances like prescription opioids can lead to tolerance, which means a patient may need to take more of the medication to achieve the same level of pain relief. In addition, physical dependence can develop, resulting in withdrawal symptoms when the medication is stopped, and there may be an increased sensitivity to pain. Other effects of opioids include increased risks of health conditions such as colon cancer, osteoporosis, and heart disease. Psychoactive drugs can also cause serious side effects like insomnia, depression, and euphoria, as well as impaired cognitive and motor functions.
