What should a nurse recommend to a client experiencing a chronic headache from isosorbide mononitrate?

For a client experiencing chronic headaches due to isosorbide mononitrate, taking the medication with food can help mitigate the side effects associated with the medication. Isosorbide mononitrate is a long-acting nitrate commonly used to treat angina and can result in side effects such as headaches due to its vasodilatory effects. Consuming the medication with food may help lessen the occurrence or intensity of these headaches by stabilizing its absorption and reducing gastrointestinal irritation.

Other options involve more extreme actions, such as altering the medication regimen without consulting a healthcare provider. While the correct approach can certainly help manage the side effects, it's important for any changes to the medication schedule or dosage to be guided by a healthcare professional to ensure safety and efficacy in treatment.
