Metoprolol Blue Pill

You are perfect!
I was looking for the diff between Metoprolol Tartrate with C75, or M47.
As time is always a factor, I appreciated it that you provided the answer in a very concise way, and I plan to return to your site.

HI Gwendolyn,

I'm so happy that you received the answer you were searching for! That is the great thing about this community, we're all here to provide information and help each other out in times of need. :) I'll provide some information about Metoprolol down below for others who may come across this thread:


Metoprolol is a selective ß1 receptor blocker used in treatment of several diseases of the cardiovascular system, especially hypertension. It is used for a number of conditions including: hypertension, angina, acute myocardial infarction, supraventricular tachycardia, ventricular tachycardia, congestive heart failure, and prevention of migraine headaches.

The active substance, metoprolol, is employed either as metoprolol succinate or metoprolol tartrate (where 100mg metoprolol tartrate corresponds to 95mg metoprolol succinate). The tartrate is an immediate-release and the succinate is an extended-release formulation.

Adverse reactions:

Side effects, especially with higher dosages, include the following: dizziness, drowsiness, fatigue, diarrhea, unusual dreams, ataxia, trouble sleeping, depression, and vision problems. It may also reduce blood flow to the hands and feet, causing them to feel numb and cold; smoking may worsen this effect. Due to the high penetration across the blood brain barrier, lipophilic beta blockers such as propranolol and metoprolol are more likely than other less lipophilic beta blockers to cause sleep disturbances such as insomnia and vivid dreams and nightmares.

Serious side effects which are advised to be reported immediately include, but are not limited to, symptoms of bradycardia (a very slow heartbeat (less than 50bpm)), persistent symptoms of dizziness, fainting and unusual fatigue, bluish discoloration of the fingers and toes, numbness/tingling/swelling of the hands or feet, sexual dysfunction, erectile dysfunction (impotence), hair loss, mental/mood changes, depression, trouble breathing, cough, dyslipidemia, and increased thirst. Other highly unlikely symptoms include easy bruising or bleeding, persistent sore throat or fever, yellowing skin or eyes, stomach pain, dark urine, and persistent nausea.

Symptoms of an allergic reaction include: rash, itching, swelling, and severe dizziness. Taking it with alcohol might cause mild body rashes and therefore is not recommended.

I hope this helps!
