What are the Common Lopressor® Side Effects?

Lopressor®, a beta-blocker drug used to treat high blood pressure and angina, has a wide array of possible side effects, though they are not reported by most patients. They can range from minor annoyances such as dizziness and low energy to serious conditions such as hepatitis and allergic reactions. Though not all adverse reactions can be known before administration of the drug, it is advisable to provide the prescribing doctor with a complete medical history in order to proactively address as many potential problems as possible.

The most commonly reported mild Lopressor® side effects are dizziness, drowsiness, and low energy. Itching and an unusual rash have developed in many users. Sexual problems are also among the most reported side effects.

Some less-common Lopressor® side effects include depression, bronchospasm, and chronic heart failure. Patients may also experience constriction of blood vessels in the extremities. This could result in lower than normal blood pressure.

There are also several rare Lopressor® side effects. Among the most severe are allergic reactions, abnormal or slow heartbeat, and hepatitis. Some patients may also experience blurred vision, joint or chest pain, and ringing in the ears. All of these symptoms should be reported to a medical professional immediately. Insomnia is one of the few rare, but not immediately life-threatening side effects of taking Lopressor®.

In order to lower the risk of adverse Lopressor® side effects, there are several conditions that a patient should disclose to a doctor before taking the drug. These conditions may prove to be too high a risk for the patient to take the drug. It is also possible that the doctor may simply need to monitor the patient on a regular basis while the drug is being taken. Conditions of the heart, including disease, congestive heart failure, irregular heart rhythm, or previous heart attacks, should be disclosed. Asthma, bronchitis, emphysema, and chronic obstructive pulmonary disease can all potentially increase the risk of taking Lopressor®.

More potentially problematic pre-existing conditions that could affect the safety of taking Lopressor® include kidney disease, psoriasis, and depression. A slow heart rate, blood vessel disease, or circulation problems such as Raynaud’s phenomenon can be of concern. All allergies, including to food, environmental elements, and drugs — particularly reactions to beta-blockers — should also be disclosed to the prescribing doctor.

There are also situations which may exclude a patient from taking Lopressor®. Pregnant or nursing women are typically advised to avoid or take the drug under careful observation. Individuals who have surgery or a procedure requiring anesthesia should also disclose that information to their doctor.
