Drug Description


Adalat XL is a prescribed medication for managing hypertension (elevated blood pressure) and regulating angina (chest pain). 

As a calcium-channel blocker, Adalat XL reduces blood pressure by relaxing blood vessels, thereby reducing the heart’s workload. On the other hand, it manages chest pain by improving blood and oxygen flow to the heart. 

Uses and Dosage 

Before taking Adalat XL and with every prescription refill, thoroughly review the accompanying medication guide and patient information leaflet. If you have any inquiries or concerns, seek advice from your healthcare provider or pharmacist. 

The dosage of Adalat XL is individualized based on the patient’s medical condition and response to the treatment.  

Your doctor may initiate treatment with a low dose, gradually adjusting it as needed. Adhere closely to your doctor’s guidance in this regard. 

Typically, Adalat XL is taken once daily, preferably on an empty stomach, either one hour before or two hours after eating.  

Ingest the tablets whole, without crushing, cutting, or chewing, to avoid potential side effects associated with rapid drug release. 

To maximize effectiveness, take Adalat XL consistently and exactly as directed at the same time daily. Seek medical advice before making any changes to the dosage or frequency of usage. 

Consult your doctor before discontinuing this medication, as abrupt discontinuation may exacerbate your condition. Your doctor may recommend gradually reducing the dosage.

Before starting treatment with Adalat XL, inform your doctor if you have any known allergies, particularly to nifedipine or to other calcium channel blockers (e.g., felodipine, amlodipine). 

Ask your pharmacist for more details about Adalat XL, as it could contain inactive components that may lead to allergic reactions or other adverse effects. 

To ensure Adalat XL is safe for you, disclose to your doctor your medical background, especially if you have a history of:

Inform all your healthcare providers about any current or recently discontinued medications, including prescription and over-the-counter drugs, as well as vitamins and herbal supplements, to lower the risk of drug interaction with Adalat XL.

Grapefruit consumption should be avoided while taking Adalat XL to prevent potential adverse effects. 

Adalat XL may cause dizziness. Refrain from driving, operating machinery, or engaging in activities requiring alertness until you feel you can do so safely. 

Prior to undergoing surgery, inform the surgeon about your usage of Adalat XL. It may be necessary for you to discontinue the medication at least 36 hours before the surgical procedure. 

The potential impact of Adalat XL on a developing fetus is uncertain. Inform your healthcare provider if you are currently pregnant or intending to conceive.
