This can lead to dizziness, fainting, heart attack, or stroke. Additionally, people with severe heart disease, recent heart attack or stroke, low blood pressure, or certain liver/kidney problems should consult a doctor before taking Vidalista 40. However, it is important to use Vidalista 40 as prescribed by a healthcare provider to ensure safety and effectiveness. Common side effects may include headaches, dizziness, flushing, upset stomach, or back pain. In rare cases, more serious side effects can occur, so you should seek immediate medical attention if you experience sudden vision or hearing loss, or painful erections lasting more than 4 hours. Men who are currently taking nitrates, or have certain heart, liver, or kidney conditions, should avoid Vidalista 40 due to the potential for serious interactions that may cause a dangerous drop in blood pressure.
