Tadalista CT 20 can sometimes cause a rapid heartbeat (palpitations or tachycardia), but it is not very common. Tadalista CT 20 contains Tadalafil, which works by relaxing blood vessels and increasing blood flow. Because it also slightly affects blood pressure, some people may feel their heart beating faster. Why rapid heartbeat may happen Mild drop in blood pressure → reflex increase in heart rate Anxiety or ***** activity (which naturally increases heart rate) Alcohol use along with the tablet Dehydration or overheating Sensitivity to tadalafil When it is more likely Higher doses or first-time use People with underlying heart conditions If combined with other blood pressure or stimulant substances When to worry Seek medical help if you have: Persistent or very fast heartbeat Chest pain or pressure Dizziness or fainting Shortness of breath Important safety note Do not use tadalafil with nitrate medicines (used for chest pain), as this can cause a dangerous drop in blood pressure and may trigger serious heart symptoms.
