Avoid combining Losartan and Viagra without your doctor’s explicit approval. Concurrent use can increase the risk of several side effects, primarily related to blood pressure.
Hypotension
Both Losartan, an angiotensin receptor blocker (ARB), and Viagra (sildenafil), a phosphodiesterase-5 (PDE5) inhibitor, can lower blood pressure. This combined effect can lead to hypotension (low blood pressure), causing dizziness, lightheadedness, or fainting, especially upon standing up quickly. Monitor your blood pressure regularly if you are considering this combination.
Other Potential Side Effects
While hypotension is the most significant concern, other side effects are possible. These may include headaches, flushing, nasal congestion, and visual disturbances. The severity and likelihood vary from person to person.
Medication Interactions Table
| Nitrates | Severe hypotension | Dizziness, fainting |
| Alpha-blockers | Increased hypotensive effect | Lightheadedness, postural hypotension |
| Other PDE5 inhibitors (e. g., Tadalafil) | Increased risk of hypotension | Similar to Losartan/Viagra combination |
Recommendations
Always inform your doctor about all medications you are taking, including over-the-counter drugs and supplements. They can assess your individual risk and determine if the benefits of combining Losartan and Viagra outweigh the potential risks. Never adjust your medication dosage without consulting your healthcare provider.
