Seek immediate medical attention if you experience chest pain, irregular heartbeat, or sudden vision changes after taking Viagra. These can be signs of a serious heart problem. Headaches, facial flushing, and nasal congestion are common, usually mild and temporary. However, if a headache is severe or persistent, contact your doctor.
Gastrointestinal Issues
Upset stomach, indigestion, or diarrhea are possible. These side effects are generally mild and resolve quickly. If symptoms worsen or persist, consult a healthcare professional. Drink plenty of water to help alleviate gastrointestinal discomfort. Avoid alcohol while taking Viagra, as it can exacerbate these effects.
Muscle Aches and Back Pain
Muscle aches and back pain are relatively common. These usually subside within a few hours. Rest and over-the-counter pain relievers like ibuprofen or acetaminophen can provide relief. If the pain is severe or persistent, seek medical advice.
