Precautions and Warnings With Metipranolol
There are many precautions and warnings with metipranolol to be aware of. For example, you should not use this drug if you have asthma, severe COPD, or severe heart failure (as metipranolol can worsen these conditions). It is also important that you talk to your healthcare provider before using metipranolol if you have diabetes, heart block, or hyperthyroidism.
You should talk with your healthcare provider prior to using metipranolol (OptiPranolol®) if you have:
- Chronic obstructive pulmonary disease (COPD)
- Heart failure
- Had a recent heart attack
- A slow heart rate (bradycardia)
- Heart block
- An upcoming surgery
- Any allergies, including allergies to food, dyes, or preservatives.
Also, let your healthcare provider know if you are:
- Pregnant or thinking of becoming pregnant
Make sure to tell your healthcare provider about any other medications you are taking, including prescription and non-prescription medicines, vitamins, and herbal supplements.
Warnings and precautions to be aware of prior to using metipranolol include the following:
- Even though metipranolol is an eye drop, a significant amount of the medication may be absorbed into the bloodstream. Therefore, most of the usual warnings of precautions with other beta blockers also apply to metipranolol.
- Beta blockers can worsen breathing problems like asthma or COPD. In many cases, metipranolol is not recommended for people with such lung problems.
- Like all beta blockers, metipranolol can worsen heart failure in some situations. If you have heart failure, your healthcare provider may need to monitor you very closely while you take metipranolol. Let your healthcare provider know immediately if your heart failure symptoms seem to worsen.
- Beta blockers can mask some of the symptoms of low blood sugar (hypoglycemia), particularly the "racing heart" feeling. This can cause serious problems for people with diabetes, who need to be able to sense that they have low blood sugar (in order to correct it before it becomes life-threatening). Some beta blockers may also worsen low blood sugar, although it is not known if this is a problem for metipranolol.
- If you will be having surgery, make sure your surgeon and anesthesiologist know you take metipranolol, as it may affect the choice of medications used during the surgery.
- Beta blockers can mask some of the symptoms of an overactive thyroid (hyperthyroidism).
- Metipranolol can potentially interact with a number of other medications (see Drug Interactions With Metipranolol).
- Metipranolol is considered a pregnancy Category C medication. This means that it may not be safe for use during pregnancy, although the full risks are not currently known (see OptiPranolol and Pregnancy).
- It is unknown if metipranolol passes through breast milk in humans. Therefore, if you are breastfeeding or plan to start breastfeeding, discuss this with your healthcare provider prior to taking the drug (see OptiPranolol and Breastfeeding).
