Always consult your doctor before taking Viagra, especially if you have pre-existing health conditions. This is particularly crucial if you have heart problems, high or low blood pressure, liver or kidney disease, or blood cell disorders.
Medication Interactions
- Viagra can interact negatively with nitrates (used to treat angina) and some other medications. Avoid combining Viagra with these drugs. Inform your doctor about all medications, supplements, and herbal remedies you are currently taking.
A 100mg dose is higher than the typical starting dose. Your doctor will determine the appropriate dosage for you based on your individual needs and health status.
Potential Side Effects
Common side effects include headache, flushing, nasal congestion, and visual disturbances. These are usually mild and temporary.
Serious Side Effects: Seek Immediate Medical Attention
Prolonged erection (priapism) lasting more than four hours. This is a medical emergency. Sudden vision loss or hearing loss. Chest pain, shortness of breath, or irregular heartbeat. Severe allergic reactions (rash, itching, swelling).
While these serious side effects are rare, they require prompt medical attention.
Lifestyle Considerations
- Avoid alcohol consumption before and during Viagra use. Alcohol can intensify side effects. Avoid grapefruit juice, as it can affect how your body processes the medication. Maintain a healthy lifestyle including a balanced diet and regular exercise.
Dosage Adjustments
The 100mg dosage might be adjusted based on individual responses and effectiveness. Your doctor may recommend a lower dose if side effects are problematic, or a higher dose if the desired effect isn’t achieved. This decision should always be made in consultation with a healthcare professional.
