Medication Interactions
Inform your doctor about your pre-existing or OTC medications, including over-the-counter (OTC) drugs, vitamins, and herbal supplements.
Nitrate Medications
Do not take a Generic Viagra Professional if you are using nitrates, such as nitroglycerin, isosorbide dinitrate, or isosorbide mononitrate for chest pain or heart issues. The combination can cause a dangerous drop in blood pressure.
Other Blood Pressure Medications
If you take alpha-blockers or other medications to control blood pressure, combining these medications with sildenafil may lead to hypotension.
Limit Alcohol
Excessive alcohol consumption can reduce the effectiveness of sildenafil and increase the risk of side effects like dizziness, headaches, or fainting because of lowered blood pressure.
Avoid Recreational Drugs
Avoid using recreational drugs such as "poppers" (amyl nitrite, butyl nitrite), which can dangerously interact with sildenafil.
Older Adults
Men over 65 may be more sensitive to the effects of sildenafil. Doctors would recommend lower doses.
Pre-Existing Health Conditions
If you have cardiovascular conditions or your doctor has advised that sexual activity is not safe for you because of heart problems, you should not take this medication.
Follow Recommended Dosage
Never exceed the prescribed dose, typically 100 mg for a Generic Viagra Professional. Taking more than the recommended dose increases the risk of side effects and complications.
Timing of Use
Take the medication about 20-30 minutes before planned sexual activity. Avoid taking it more than once a day.
Food Intake
Avoid heavy or fatty meals before taking Generic Viagra Professional, as they can delay its effectiveness.
Mild Side Effects
These include headaches, flushing, dizziness, indigestion, and nasal congestion. If these symptoms persist or worsen, consult a doctor.
Vision or Hearing Issues
Sildenafil may cause sudden vision or hearing loss. If you experience this, stop taking the medication and seek immediate medical help.
Priapism
If you experience an erection lasting over 4 hours (a condition called priapism), seek emergency medical help to avoid permanent damage to the penis.
Women and Children
Generic Viagra Professional is not for use by women or individuals under 18 years of age.
Allergy to Sildenafil
If you are allergic to sildenafil or any other ingredients in the drug, do not take a Generic Viagra Professional. Signs of an allergic reaction include rash, itching, swelling, severe dizziness, or trouble breathing.
Physical Exertion
Sildenafil can lower blood pressure, which may cause dizziness or fainting, especially after physical exertion. Exercise caution when engaging in activities that require balance or coordination after taking the medication, such as driving, riding, operating machinery, or tasks that require mental or physical alertness.
Avoid Mixing ED Medications
Do not combine Generic Viagra Professional with other erectile dysfunction treatments like tadalafil, vardenafil, Avanafil, or other forms of sildenafil. It can lead to an overdose or increased side effects.
