When it comes to combining medications, especially those that affect the respiratory system and allergies, it is crucial to understand the potential interactions and side effects. In your case, you are asking about the use of Taisho Hay Fever Medicine (大正百寶能) alongside antihistamines, specifically the nasal medication you took the night before.

Taisho Hay Fever Medicine is a combination product that typically contains ingredients aimed at alleviating symptoms of allergies, such as nasal congestion, sneezing, and runny nose. These products often include components like decongestants, which can have stimulating effects, and sometimes other ingredients that may not be compatible with antihistamines.

Antihistamines, such as the one you took (力波), work by blocking the action of histamine, a substance in the body that causes allergic symptoms. While antihistamines are effective for treating allergy symptoms, they can also cause drowsiness, especially the first-generation antihistamines. When combined with other medications that may have sedative effects or other interactions, there can be an increased risk of side effects, including excessive sedation or impaired cognitive function.

The warning against taking Taisho Hay Fever Medicine with antihistamines likely stems from the potential for overlapping effects, particularly if the hay fever medicine contains ingredients that could exacerbate the sedative effects of antihistamines. This could lead to increased drowsiness, dizziness, or other side effects that could impair your ability to function normally.

In your situation, since you took the antihistamine the night before and then took the Taisho Hay Fever Medicine throughout the day, it is essential to monitor how you feel. If you experience increased drowsiness, confusion, or any unusual symptoms, it would be wise to consult with a healthcare professional. They can provide guidance based on your specific health history and the exact ingredients in the medications you are taking.

In general, when dealing with multiple medications, it is always best to consult with a healthcare provider or pharmacist. They can provide personalized advice and ensure that your treatment plan is safe and effective. If you have ongoing symptoms of nasal congestion or allergies, consider discussing alternative treatments or adjustments to your medication regimen with your healthcare provider.

In summary, while you may not experience immediate adverse effects from taking Taisho Hay Fever Medicine with an antihistamine, caution is warranted due to the potential for increased sedation and other side effects. Always prioritize open communication with your healthcare provider regarding any medications you are taking, especially when combining different treatments.
