If you have a cold or flu symptoms and need relief, it's best to talk to a healthcare professional or a pharmacist. They can provide appropriate guidance on which medications are safe and suitable for your specific condition. They can also review your medical history and current medications to ensure there are no potential interactions.
Always read the labels of over-the-counter medications carefully and follow the recommended dosages. If you are currently taking any other medications or have underlying health conditions, inform your healthcare provider before taking any new medication, including over-the-counter products like NyQuil. They can help you make informed decisions about the best course of treatment for your condition.
