Drug Interaction Report

Vosoritide may cause transitory decreases in blood pressure and may have additive effects when used together with guanFACINE. You may be more likely to experience side effects such as dizziness, weakness, headache, nausea, flushing or fainting. You may need frequent monitoring of your blood pressure to safely use both medications. To reduce the risk of low blood pressure and its associated symptoms, you should have adequate food intake before vosoritide administration and should drink approximately 8 to 10 ounces of liquids within the hour prior to vosoritide injection. Avoid driving or operating hazardous machinery until you know how these medications affect you and use caution when getting up from a sitting or lying position. 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.

Avoid consuming grapefruit or grapefruit juice during treatment with guanFACINE, as it may increase blood levels and effects of the medication. This may cause blood pressure to fall excessively, especially when you rise from a sitting or lying position. The risk of other side effects such as drowsiness, dizziness, lightheadedness, fainting, headache, palpitations, and heart rate changes may also increase. Additionally, you should avoid or limit the use of alcohol while being treated with guanFACINE. Combining the medication with alcohol can intensify sedative and blood pressure lowering effects, which may increase the risk of falls and injury. Avoid driving or operating hazardous machinery until you know how the medication affects you, and use caution when getting up from a sitting or lying position. If you are using a long-acting or extended-release formulation of the medication, make sure you do not take it with a high-fat meal. Doing so results in increased absorption and elevated blood levels of the medication. Talk to your doctor or pharmacist if you have any questions or concerns.
