Side effects, also called adverse reactions, are undesirable and unwanted effects that result from a medication or treatment. They occur when the treatment does more than treat the intended issue.
Treatments that cause side effects can include over-the-counter drugs, prescription medications, vitamin supplements, or alternative, complementary, and herbal therapies.
In most cases, side effects are mild, with some common side effects including:
- dry mouth
- skin rash
Side effects typically go away once the medication or treatment causing them has been discontinued. However, some side effects are more serious and require medical interventions.
The severity of side effects can vary by individual, with factors such as disease state, general health, weight, age, and gender influencing the side effects that appear and how severe they are.
