Begma 100 is an oral medication primarily used to treat erectile dysfunction (ED) in men. It belongs to the class of phosphodiesterase type 5 (PDE5) inhibitors, which work by increasing blood flow. Begma 100 contains sildenafil citrate, which inhibits the enzyme phosphodiesterase type 5 (PDE5). By blocking PDE5, sildenafil helps to increase levels of cyclic guanosine monophosphate (cGMP) in the body. This leads to relaxation of smooth muscle. it may not be suitable for everyone. It's important to inform your healthcare provider about any medical conditions you have, especially if you have a history of cardiovascular problems or are taking medications that could interact with sildenafil. Common side effects may include headache, flushing, indigestion, nasal congestion, and visual disturbances, but these are usually mild and transient. Before starting Begma 100 or any ED medication, it's crucial to have a thorough discussion with a healthcare provider.
