Moderate
Metoprolol Succinate Er
+ Food
The following applies to the ingredients: Metoprolol (found in Metoprolol Succinate Er)
Food can enhance the levels of metoprolol in your body. You should take metoprolol at the same time each day, preferably with or immediately following meals. This will make it easier for your body to absorb the medication. Avoid drinking alcohol, which could increase drowsiness and dizziness while you are taking metoprolol. Metoprolol is only part of a complete program of treatment that also includes diet, exercise, and weight control. Follow your diet, medication, and exercise routines very closely.
The following applies to the ingredients: Metoprolol (found in Metoprolol Succinate Er)
Using metoprolol together with multivitamin with minerals may decrease the effects of metoprolol. Separate the administration times of metoprolol and multivitamin with minerals by at least 2 hours. If your doctor does prescribe these medications together, you may need a dose adjustment or special test to safely use both medications. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
Drug and Pregnancy Interactions
Major
Omeprazole
+ Pregnancy
The following applies to the ingredients: Omeprazole
Professional Content
This drug should be used during pregnancy only if the benefit outweighs the risk to the fetus.
AU TGA pregnancy category: B3
US FDA pregnancy category: Not assigned.
Risk Summary: Epidemiologic studies have demonstrated that major malformative risks with use in pregnant patients are unlikely.
Comment: Some experts recommend that use is considered acceptable.
Animal models have revealed evidence of dose-related increases in embryolethality, fetal resorptions, and pregnancy disruptions when animal models were given this drug during organogenesis. Major fetal malformations were not frequently observed in animal models. Embryofetal and postnatal developmental toxicities were observed in offspring of parents given at least 3.4 times an oral human dose of 40 mg.
Embryofetal toxicity is associated with maternally toxic doses given throughout gestation as well as in high doses given to males prior to mating.
AU TGA pregnancy category B3: Drugs which have been taken by only a limited number of pregnant women and women of childbearing age, without an increase in the frequency of malformation or other direct or indirect harmful effects on the human fetus having been observed. Studies in animals have shown evidence of an increased occurrence of fetal damage, the significance of which is considered uncertain in humans.
US FDA pregnancy category Not Assigned: The US FDA has amended the pregnancy labeling rule for prescription drug products to require labeling that includes a summary of risk, a discussion of the data supporting that summary, and relevant information to help health care providers make prescribing decisions and counsel women about the use of drugs during pregnancy. Pregnancy categories A, B, C, D, and X are being phased out.

Major
Metoprolol Succinate Er
+ Pregnancy
The following applies to the ingredients: Metoprolol (found in Metoprolol Succinate Er)
Professional Content
US: This drug should be used during pregnancy only if clearly needed.
AU and UK: Use is not recommended unless benefit outweighs risk; if used during pregnancy, administer the lowest possible dose and discontinue at least 2 to 3 days prior to expected delivery, if possible.
AU TGA pregnancy category: C
US FDA pregnancy category: C
Animal studies have revealed increased postimplantation loss, fetolethality, and decreased neonatal survival. There are no controlled data in human pregnancy.
AU TGA pregnancy category C: Drugs which, owing to their pharmacological effects, have caused or may be suspected of causing, harmful effects on the human fetus or neonate without causing malformations. These effects may be reversible. Accompanying texts should be consulted for further details.
US FDA pregnancy category C: Animal reproduction studies have shown an adverse effect on the fetus and there are no adequate and well-controlled studies in humans, but potential benefits may warrant use of the drug in pregnant women despite potential risks.

Professional Content
Use is not recommended.
Excreted into human milk: Yes
Comments:
-This drug is associated with tumorigenicity in animal models, and may suppress gastric acid secretion in the nursing infant.
-The American Academy of Pediatrics state that this drug should be avoided until additional studies can confirm the safe use of this drug during breastfeeding.
In animal models, decreased postpartum offspring growth rates were observed when this drug was administered during late gestation and throughout lactation at oral doses of at least 138 mg/kg/day and IV doses of 3.2 mg/kg/day.
