Metoprolol SR for Hypertension and Angina

Metoprolol SR is a sustained-release beta blocker used for heart conditions. This page explains uses, dosing, safety, and how to access it. We arrange delivery from Canada to the US with Canadian pricing. You can compare options and potential savings without insurance.

What Metoprolol SR Is and How It Works

Metoprolol SR is a sustained-release form of metoprolol, a selective beta-1 blocker. It lowers heart rate, reduces blood pressure, and lessens cardiac workload. That helps control hypertension, prevent angina attacks, and support recovery after a heart attack. Certain SR formulations are also used in stable heart failure, as directed by labeling. At CanadianInsulin, orders are filled by licensed Canadian pharmacies after we confirm a valid prescription with your clinic. Many patients choose this option for US delivery from Canada.

Who Metoprolol SR Is For

Metoprolol SR is prescribed for adults with high blood pressure and chronic stable angina. Extended-release metoprolol succinate is also indicated for stable heart failure in many treatment plans. It can be used after a heart attack to reduce recurrent events, as instructed on the label.

It may not be suitable if you have severe bradycardia, second- or third-degree heart block without a pacemaker, sick sinus syndrome without a pacemaker, cardiogenic shock, or decompensated heart failure. Use caution with asthma, COPD, severe peripheral arterial disease, or diabetes. Discuss risks and benefits with your clinician, especially if you are pregnant or breastfeeding.

Dosage and Usage

Follow your prescription label exactly. Do not change your dose without medical advice.

• Hypertension: Common initiation is 25 mg to 100 mg once daily. Your clinician may increase the dose every 1 to 2 weeks to improve control.
• Angina: Typical starting doses are 50 mg to 100 mg once daily. Your dose may be adjusted based on symptom control and heart rate.
• Heart failure (extended-release succinate only): A common start is 12.5 mg to 25 mg once daily. Doses are usually doubled every two weeks as tolerated. Many patients target 200 mg once daily.
• Post–myocardial infarction: Once stabilized, extended-release metoprolol may be used once daily per the official label.

Most patients take SR tablets with or right after a meal. Swallow tablets whole. Do not crush, break, or chew sustained-release tablets.

Strengths and Forms

Metoprolol SR is commonly available as sustained-release tablets in these strengths:

• 25 mg SR tablets
• 50 mg SR tablets
• 100 mg SR tablets
• 200 mg SR tablets

Packaging varies by manufacturer. Availability may differ by pharmacy and jurisdiction.

Missed Dose and Timing

If you miss a dose, take it when you remember the same day. If it is almost time for your next dose, skip the missed dose. Do not double up. Try to take the tablet at the same time each day for steady control.

Storage and Travel Basics

Store tablets at room temperature in a dry place. Keep the bottle tightly closed and away from moisture and light. Do not store in a bathroom. For travel, keep medicine in your carry-on, in original labeled packaging. Bring enough supply and your prescription details for US travel from Canada. Avoid extreme heat or cold.

Benefits

• Once-daily sustained release simplifies dosing for many patients.
• Helps lower blood pressure and reduce angina episodes.
• Supports post–heart attack therapy per guideline-driven care.
• Extended-release succinate can improve heart failure outcomes when used as directed.

Side Effects and Safety

• Common: Fatigue, dizziness, lightheadedness, slow heart rate.
• Gastrointestinal: Nausea, diarrhea, or constipation.
• Neurologic: Headache or sleep changes.
• Extremities: Cold hands and feet.

Serious effects can include very slow heart rate, low blood pressure, heart block, worsening heart failure, bronchospasm, depression, or allergic reactions. Beta blockers can mask warning signs of low blood sugar. People using insulin or sulfonylureas should monitor closely and discuss plans with their clinician. Seek urgent care for fainting, chest pain that worsens, breathing problems, or swelling in the legs.

Drug Interactions and Cautions

• Heart rate–lowering agents: Risk of bradycardia with verapamil or diltiazem.
• Antiarrhythmics: Added effects with drugs like amiodarone or propafenone.
• CYP2D6 inhibitors: Medicines such as paroxetine or fluoxetine may raise levels.
• Clonidine: Tapering requires care; coordinate changes with your clinician.
• NSAIDs: May reduce antihypertensive effect in some patients.
• Alcohol: Can enhance blood pressure–lowering and dizziness.

Tell your clinician and pharmacist about all prescription and over-the-counter products, vitamins, and supplements. For related reading, see Acebutolol Uses. Encrypted checkout protects your information during purchase.

What to Expect Over Time

Blood pressure often improves over one to two weeks. Angina episodes may become less frequent with regular use. Your resting heart rate should lower and feel steadier. Full benefits for heart failure require slow dose increases and regular follow-up. Your clinician will monitor blood pressure, heart rate, and symptoms and adjust treatment as needed.

Compare With Alternatives

Other beta blockers may suit your goals, health history, or tolerability. Tenormin® contains atenolol and is often used for blood pressure and angina. Bisoprolol Zebeta is another cardioselective option that some patients tolerate well. Calcium channel blockers, such as amlodipine, may be used when a beta blocker is not preferred. Your clinician can help match therapy to your condition and goals.

Many patients compare metoprolol SR cost online and choose multi-month refills. US delivery from Canada helps you access consistent supply. Some patients look for savings without insurance through generic options.

Availability and Substitutions

Supply can vary by strength, manufacturer, and pack size. If a specific SR strength is not available, your prescriber may recommend a compatible alternative or a different dose. Do not substitute short-acting metoprolol for sustained-release without clinical guidance.

Patient Suitability and Cost Saving Tips

• Good candidates include adults with hypertension or angina who need once-daily coverage.
• Extended-release succinate can benefit eligible patients with stable heart failure.
• Not ideal for severe bradycardia, advanced heart block without pacing, or acute decompensated heart failure.
• Ask about a 90-day fill to reduce per-tablet cost and fewer refills.
• Set refill reminders so you do not miss doses during travel.
• Keep a blood pressure and heart rate log to guide appointments.
