Kamagra 50 mg (sildenafil 50 mg) can be linked to dizziness in some people. Dizziness is a known side effect and may happen because sildenafil can lower blood pressure by relaxing blood vessels. It may be more noticeable: When standing up quickly If you are dehydrated (for example, during fasting or heavy sweating) If you drink alcohol If you take medicines that also lower blood pressure Other possible side effects include: Headache Flushing (warmth/redness of the face) Indigestion Nasal congestion Temporary vision changes Seek medical help urgently if dizziness is severe, you faint, have chest pain, severe headache, sudden vision/hearing changes, or an erection lasting more than 4 hours. If you tell me your age, whether you took Kamagra 50 mg recently, and whether you were fasting, dehydrated, or taking BP/heart medicines, I can help assess how likely it is that Kamagra caused the dizziness.
