Sildigra 100 mg, which contains Sildenafil (the same active ingredient found in Viagra), is a medication used to treat erectile dysfunction (ED) by increasing blood flow to the penis. While it is generally safe for most users when taken as prescribed, it can potentially cause side effects, including cardiovascular issues.

Irregular heartbeat (arrhythmia) is a possible but rare side effect of Sildigra 100 mg. This can occur due to the way the drug affects the cardiovascular system by dilating blood vessels and increasing blood flow. If you have a history of heart problems or are taking medications that affect the heart, this risk may be higher.

If you experience symptoms such as dizziness, chest pain, shortness of breath, or an irregular heartbeat while taking Sildigra 100mg, it's important to seek immediate medical attention. It’s advisable to consult a healthcare provider before using this medication, especially if you have pre-existing heart conditions.
