Myogard OD 30 mg Tablet SR

Myogard OD 30 mg Tablet SR is a prescription medicine that contains nifedipine 30 mg in each sustained-release tablet. It belongs to the calcium channel blocker class, which helps relax blood vessels and lower blood pressure. It is used to treat high blood pressure and certain types of chest pain (angina). Because it is a sustained-release tablet, it is designed to release the medicine gradually over time.

How it works: Nifedipine blocks calcium from entering the muscle cells in the walls of blood vessels, which helps those vessels relax and widen. In this tablet form, the medicine is released slowly, so its blood-pressure and anti-angina effect lasts longer through the day.

Myogard OD 30 mg Tablet SR is a higher-strength nifedipine tablet that is meant for people whose doctor has already assessed their blood pressure or angina needs. Compared with lower-strength nifedipine products, this 30 mg sustained-release tablet may provide steadier all-day control, but it is not meant to be split, crushed, or used as an instant-relief medicine. A clinician may choose this strength when a lower dose is not enough or when a once-daily sustained effect is preferred.

• High blood pressure (hypertension)
• Chronic stable angina
• Vasospastic (Prinzmetal) angina
• Blood vessel relaxation to improve blood flow

• Swallow Myogard OD 30 mg Tablet SR whole with water.
• Do not crush, chew, or split the sustained-release tablet.
• Take it at the same time each day as prescribed by your doctor.
• You may take it with or without food unless your prescriber advises otherwise.
• If it upsets your stomach, taking it with food may help, but follow your doctor’s directions.
• Do not use this tablet for sudden chest pain unless your doctor has told you it is appropriate.

Each Myogard OD 30 mg Tablet SR provides 30 mg of nifedipine in a sustained-release form. The usual dosing schedule and the total maximum daily dose depend on the condition being treated and your response, so your doctor decides how often you should take it and whether a once-daily plan is right for you. Do not take more tablets per day than prescribed, even if your symptoms are not fully controlled.

Do not change your dose or stop the medicine without speaking to your doctor.

Common side effects of Nifedipine may include:

• Headache, which may be more noticeable when starting treatment or after dose increases
• Flushing or warmth of the face
• Dizziness or lightheadedness
• Swelling of the ankles or feet
• Feeling tired or weak
• Palpitations or awareness of heartbeat
• Nausea

• Myogard OD 30 mg Tablet SR is a higher-strength sustained-release tablet, so it should be used only if your doctor has prescribed this exact strength.
• Do not crush or chew the tablet, because that can release too much medicine too quickly.
• It may cause dizziness, so be careful driving or using machinery until you know how it affects you.
• Alcohol can worsen dizziness and lightheadedness.
• Tell your doctor if you have heart failure, severe low blood pressure, or a history of very low heart rate.
• Do not use with nitrates or other blood-pressure medicines unless your doctor has reviewed the combination.
• Let your clinician know if you develop swelling, worsening chest pain, or marked drops in blood pressure.

• Nitrates such as nitroglycerin can increase blood-pressure-lowering effects.
• Other blood pressure medicines, including beta blockers and ACE inhibitors, may add to dizziness or low blood pressure.
• Strong CYP3A4 inhibitors such as erythromycin, clarithromycin, ketoconazole, and ritonavir can raise nifedipine levels.
• Grapefruit or grapefruit juice can increase nifedipine exposure and side effects.
• Digoxin levels may be affected in some patients, so monitoring may be needed.
