• Yes, side effects of Nifedipine may include severe allergic reactions and liver or kidney problems. You must seek medical attention if you encounter any side effects, such as swelling, difficulty breathing, nausea, and rashes.

• Does Nifedipine cause edema?
• The vasodilation of Nifedipine can lead to an increased chance of fluid leakage from the blood vessels into the surrounding tissues, resulting in edema. It occurs in the lower extremities, such as the ankles and feet. It's important to monitor for signs of edema while taking this drug and inform your healthcare provider if you notice any unusual swelling or changes in your extremities.

• How long does it take time for Nifedipine to work?
• Immediate-release tablets of Nifedipine typically start working within 30 minutes to 1 hour after administration. Extended-release formulations may take longer to reach their maximum effect, with onset times ranging from 1 to 2 hours. 

• Can Nifedipine be given sublingually?
• No, Nifedipine should not be given sublingually (under the tongue). It is available in various formulations, including immediate-release tablets and extended-release capsules, which are meant to be swallowed whole with water.

• How does Nifedipine work in treating low blood pressure?
• Nifedipine works by blocking the influx of calcium ions into certain cells, leading to relaxation and dilation of blood vessels, which mainly helps to lower blood pressure and improve blood flow.

• Can I take Nifedipine with low BP?
• If you have low blood pressure (hypotension), taking Nifedipine may further decrease your blood pressure and cause symptoms such as dizziness, lightheadedness, fainting, or fatigue. Therefore, taking this drug if you have low blood pressure is generally not recommended unless specifically prescribed and closely monitored by your healthcare provider.
