Suhagra 100 mg (sildenafil) can cause dizziness in some people, but not everyone experiences it. Dizziness is more likely in people who are sensitive to sildenafil’s blood-vessel–relaxing effects or who have factors that can lower blood pressure. People who may be more likely to experience dizziness include: Those taking a higher dose of sildenafil (100 mg can cause more side effects than lower doses) Older adults, who may be more sensitive to blood pressure changes People who already have low blood pressure People who drink alcohol around the time of taking it Those taking blood pressure medicines (especially multiple medicines) or Suhagra 100 mg interacting drugs People who become dehydrated or are overheated Those with certain heart or circulation conditions To reduce the chance of dizziness: Avoid heavy alcohol use when taking Suhagra Stand up slowly if you feel lightheaded Do not take more than the prescribed amount Discuss dose adjustment with a healthcare professional if dizziness keeps happening Seek urgent medical help if dizziness is severe or occurs with fainting, chest pain, trouble breathing, sudden vision/hearing changes, or an erection lasting more than 4 hours. If you tell me when the dizziness happens (soon after taking it, during sex, or the next day) and whether you take any blood pressure or heart medicines, I can help identify the likely cause.
