Expert advice

  • Notify your doctor if you are or planning to become pregnant.
  • Nimodipine can cause swelling in the ankle or feet. Notify your doctor if it bothers you.
  • The missing dose of the Nimodipine can cause your blood pressure to go up suddenly, which raises the risk of heart attack and stroke. You can take the medicine at the same time every day to avoid forgetting it.
  • You may get a headache that lasts for a short time, after starting Nimodipine. This should become less noticeable after a few days.
     
  • Nimodipine may cause dizziness in the first few days of starting the treatment.
  • Your doctor may recommend a change in the lifestyle to lower your blood pressure. It may include: 
    • Maintain a normal body weight (body mass index, 18.5-24.9 kg/m2). 
    • Consume fruits, vegetables, low-fat dairy products, and reduce saturated-total fat.
    • Reduce daily dietary sodium intake as much as possible, ideally to 65 mmol/day (1.5 g/day sodium or 3.8 g/day sodium chloride).
    • Regular aerobic physical activity (at least 30 minutes/day, most days of the week).
    • Limit alcohol consumption to less than or equal to 2 drinks per day (1oz or 30ml ethanol eg 24oz beer, 10 oz wine, or 3 oz 80-proof whiskey).
     
  • Swelling, bleeding or tenderness of gums may occur after starting the treatment. Brushing and flossing of teeth carefully and regularly may prevent this.
