Take one tablet of Telmisartan in the morning, but blood pressure remains high in the evening. What should I do?

Generally, Telmisartan tablets are primarily used to treat hypertension. If blood pressure remains high in the evening after taking Telmisartan in the morning, the main reasons may include insufficient drug duration, drug interactions, inadequate lifestyle modifications, insufficient dosage, or coexisting other diseases. If this occurs, it is recommended to promptly visit a regular hospital to adjust the treatment plan. Detailed explanations are as follows:

1. Insufficient Drug Duration

The duration of Telmisartan's effect may vary among individuals. In some people, the drug effect may not last for 24 hours, and as the drug's action weakens in the evening, blood pressure may rise again. Under a doctor's guidance, the timing of medication can be adjusted—for example, taking the medication slightly earlier—or switching to a long-acting antihypertensive drug with a longer duration, such as Amlodipine Besylate tablets, Perindopril tert-Butylamine tablets, or Valsartan capsules.

2. Drug Interactions

If other medications are taken concurrently, they may interact with Telmisartan and affect its blood pressure-lowering effect, leading to elevated evening blood pressure. For example, taking nonsteroidal anti-inflammatory drugs (NSAIDs) may reduce the effectiveness of antihypertensive medications. It is important to inform the doctor about all medications currently being taken, and the doctor will adjust the medication regimen accordingly.

3. Inadequate Lifestyle Modifications

Elevated evening blood pressure may be related to unhealthy lifestyle habits during the day or evening, such as consuming excessive salt at dinner, which can lead to water and sodium retention, increasing blood volume and subsequently raising blood pressure. It is important to maintain emotional stability, avoid staying up late, and ensure sufficient sleep.

4. Insufficient Dosage

If the dose of Telmisartan being taken is too low, it may not effectively control blood pressure throughout the day, resulting in a rebound increase in evening blood pressure. Under a doctor's evaluation, the Telmisartan dosage may be appropriately increased or combined with other types of antihypertensive medications, such as Hydrochlorothiazide tablets, Metoprolol Tartrate tablets, or Nifedipine Controlled-Release tablets, to enhance blood pressure control.

5. Coexisting Other Diseases

If hyperthyroidism is present, excessive thyroid hormone in the body can accelerate metabolism, increase heart rate, and cause vasoconstriction, leading to elevated blood pressure. Patients with hyperthyroidism can, under a doctor's guidance, take medications such as Methimazole tablets, Propylthiouracil tablets, or Carbimazole tablets to inhibit thyroid hormone synthesis and assist in blood pressure control.

In daily life, it is important to regularly monitor blood pressure and record morning and evening fluctuations to provide reference for adjusting treatment plans; maintain a regular lifestyle and avoid excessive fatigue; eat a light diet and consume more fresh vegetables and fruits; quit smoking and limit alcohol intake to reduce triggers for blood pressure fluctuations.
