Interactions between your drugs
metoprolol ↔ pseudoephedrine
Applies to:metoprolol and Theraflu Flu & Cough (acetaminophen/chlorpheniramine/dextromethorphan/pseudoephedrine)
Consumer information for this interaction is not currently available.
MONITOR: Sympathomimetic agents, such as pseudoephedrine, may antagonize the effects of antihypertensives that interfere with sympathetic activity, such as alpha- and beta-adrenergic blocking agents. In contrast, alpha- and beta-blockers may diminish the vasoconstrictive effects of sympathomimetics. The mechanism of this interaction has not been reported, but may involve competitive inhibition at the adrenergic receptor. Severe hypertension may occur in patients receiving beta-blockers.
MANAGEMENT: Caution and close monitoring of blood pressure is recommended if pseudoephedrine is administered with these antihypertensives. Discontinuation of the sympathomimetic may be necessary if hypertension develops.

Drug and food interactions
Applies to: metoprolol
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.
Applies to: Theraflu Flu & Cough (acetaminophen / chlorpheniramine / dextromethorphan / pseudoephedrine)
Alcohol can increase the nervous system side effects of chlorpheniramine such as dizziness, drowsiness, and difficulty concentrating. Some people may also experience impairment in thinking and judgment. You should avoid or limit the use of alcohol while being treated with chlorpheniramine. Do not use more than the recommended dose of chlorpheniramine, and avoid activities requiring mental alertness such as driving or operating hazardous machinery until you know how the medication affects you. Talk to your doctor or pharmacist if you have any questions or concerns.
