This detailed guide explains Before Using, Allergies, Proper Use, Dosing, Precautions, Side Effects, FAQ, and a clear Conclusion, while naturally including important terms such as Nifedipine.

What Is Nifedipine?

Nifedipine is commonly prescribed for:

• Hypertension (high blood pressure)

• Angina (chest pain)

• Certain circulation disorders like Raynaud’s phenomenon

In some regions, it is available under brand and generic forms, including depin 5 tablet which are low-dose formulations often used at the start of therapy or in dose adjustments.

Before Using Nifedipine

Before starting Nifedipine, patients in the US should discuss their full medical history with a healthcare provider. This medication may not be suitable for everyone, especially individuals with:

• Severe aortic stenosis

• Advanced heart failure

• Very low blood pressure

• Recent heart attack

Your doctor may also review your current medications to avoid interactions, particularly with beta-blockers, antifungal drugs, or antibiotics.

Allergies

Do not use Nifedipine if you are allergic to:

• Nifedipine itself

• Other calcium channel blockers (if previously advised by a doctor)

Signs of an allergic reaction include rash, itching, swelling (especially of the face or throat), severe dizziness, or trouble breathing. Seek emergency medical help immediately if these occur.

Proper Use

For safe and effective results:

• Take Nifedipine exactly as prescribed

• Swallow tablets whole with water

• Do not crush or chew extended-release tablets

• Take it at the same time each day

Low-dose options like depin 5mg or depin 5 tablet may be prescribed initially to reduce the risk of side effects, especially in older adults.

Avoid grapefruit or grapefruit juice, as it can increase Nifedipine levels in the blood and raise the risk of adverse effects.
