What are the warnings for taking Metoprolol (Lopressor)?
Metoprolol is a treatment and not a cure for the conditions it is used to treat. It may take a few weeks until you can start to notice the benefits of the medication. Certain allergies may worsen the reactions to the drug, this can include being unresponsive to epinephrine. If you have asthma, heart failure (in some cases) or a slow heart rate, beta blocker medication is not recommended.
Doctors normally do not prescribe the drug to those who suffer from diabetes or people older than 65.
However, it is often dependent on the health of the person. It is always best to consult with a doctor should you have any of these conditions.
Metoprolol warnings include:
- Surgery: You should let your doctor know if you are expecting to have surgery done, this also includes dental surgery.
- Asthma or chronic obstructive pulmonary disease (COPD): It is best not to take metoprolol if you are asthmatic or have other breathing related issues. This is due to the fact that metoprolol is able to block receptors in the breathing passages, narrowing them and worsening any breathing problems you may have.
- Diabetes: Metoprolol can eliminate tremors and increase your heart rate, which are both indications of low blood sugar. If these signals are not present, it can be harder to recognise the signs of low blood sugar, thus making it dangerous for people with diabetes to take the drug.
- Poor blood circulation: Having bad circulation in your hands and feet can be worsened by taking metoprolol as the drug decreases blood pressure, resulting in less blood flow to these areas.
- Breast feeding: Metoprolol can enter your breast milk and be passed to your baby when breastfeeding, it can be dangerous to the health of the baby.
- Pregnancy: With metoprolol being a category C drug, it means that research conducted on animals has shown negative effects on the foetus when the mother is taking the drug. In addition, it means that there haven’t been enough studies conducted on humans to draw conclusive findings on how this drug will affect your unborn child.
- Seniors: Seniors are often given a smaller dose of metoprolol first, with it then increasing gradually.
- Children and teenagers: Children between the ages of one and 17 are able to be given the immediate-release form of metoprolol.
