Phenytoin has common side effects that include excessive body hair growth and which other effect?

1. Nausea and vomiting

2. Weight gain

3. Increased appetite

4. Insomnia

The correct answer is: Nausea and vomiting

Phenytoin is an anticonvulsant medication commonly used to manage seizures. Among its side effects, excessive body hair growth, known as hirsutism, is well-documented. Additionally, nausea and vomiting are frequently reported side effects associated with this medication. The gastrointestinal disturbances can occur due to phenytoin’s effects on the central nervous system and its ability to irritate the stomach lining. As the body adjusts to the medication, these symptoms may vary in intensity. It is important for patients to be aware of these side effects as they might need to manage them or consult their healthcare provider for adjustments in treatment. In contrast, weight gain, increased appetite, and insomnia are not commonly associated with phenytoin use. Weight gain could be influenced by other medications or lifestyle factors, while increased appetite and insomnia are not typical responses to phenytoin. Thus, recognizing nausea and vomiting as a significant side effect helps in monitoring and addressing any potential issues during treatment.
