From the Guidelines
Tadalafil and buspirone (Buspar) should be used with caution together, as the combination may increase the risk of side effects, particularly given the higher side effect risk associated with certain combinations of medications, as noted in the management of lower urinary tract symptoms attributed to benign prostatic hyperplasia 1. When considering the use of tadalafil and buspirone together, it's essential to weigh the potential benefits against the risks. The primary concern is the potential for additive effects on blood pressure, as both medications can cause hypotension. Tadalafil, a PDE5 inhibitor, causes vasodilation, while buspirone affects blood pressure through its activity on serotonin receptors.
- Patients should be aware of potential overlapping side effects, particularly related to blood pressure changes.
- Monitor for symptoms like dizziness, lightheadedness, or fainting, especially when standing up quickly.
- If symptoms occur, sit or lie down immediately and consult a healthcare provider.
- No dosage adjustments are typically needed when using these medications concurrently, but it's crucial to inform the doctor about all medications being taken, including over-the-counter drugs and supplements.
- Staying well-hydrated and avoiding alcohol is recommended, as alcohol can worsen potential blood pressure effects 1. Although another study discusses the interaction of various medications with cyclosporine, including tadalafil 1, this information is not directly relevant to the interaction between tadalafil and buspirone. Therefore, the primary consideration for the use of tadalafil and buspirone together should be based on the most recent and relevant guideline evidence, which emphasizes caution due to potential increased side effect risk 1.
From the Research
Tadalafil and Buspar (Buspirone) Interaction
- There are no research papers to assist in answering this question, as the provided studies focus on the use of tadalafil in the treatment of benign prostatic hyperplasia (BPH) and erectile dysfunction (ED), with no mention of Buspar (Buspirone) or its interaction with tadalafil 2, 3, 4, 5, 6.
- The studies discuss the efficacy and safety of tadalafil in treating BPH and ED, but do not address potential interactions with other medications like Buspar (Buspirone) 2, 3, 4, 5, 6.
- To determine the potential interaction between tadalafil and Buspar (Buspirone), further research or consultation with a medical professional would be necessary, as the provided evidence does not provide any relevant information on this topic 2, 3, 4, 5, 6.
