Daily Life Interactions for Atenolol 50mg Tablet

Elements of your daily lifestyle may have an effect on the medications you are taking. Drug interactions can result in unwanted side effects, reduce the effectiveness of your medicine or possibly increase the action of a particular medicine.

Moderate Lifestyle Interaction
Alcohol and Atenolol 50mg Tablet(Atenolol)
Alcohol and Antihypertensives(Atenolol)
Although an interaction is possible, Ethanol (alchohol) and Antihypertensive Agents (drugs used to reduce high blood pressure) may be used together. Ethanol or alchohol-containing beverages may increase the effects of Antihypertensive Agents on your blood pressure. If the blood pressure drops too low while taking Ethanol and Antihypertensive Agents, you may become dizzy or feel faint. To limit this interaction, avoid alcohol-containing beverages while taking medicines to lower your blood pressure. Do not stand or sit up too quickly. Contact your prescriber if you have dizziness which does not go away.
Moderate Lifestyle Interaction
Food and Atenolol 50mg Tablet(Atenolol)
Food and Atenolol(Atenolol)
Atenolol may be taken without regard to most food or meals. There is one small study that suggests taking atenolol with orange juice directly might moderately lower atenolol's effectiveness. More data are needed to confirm these results. Why this interaction might occur is not known at this time. Until more data are available, it may be advisable to not significantly alter your orange juice intake while taking atenolol.
