Before you start using Kamagra (Sildenafil), be sure to tell your doctor about any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breastfeeding, and any other significant health issues.
These factors can affect how you should use Kamagra (Sildenafil):
Alcohol: Drinking alcohol in large amounts can decrease the ability to get an erection and can also temporarily lower blood pressure, causing dizziness and fainting.
Blood pressure: Tell your doctor if you are taking medicines to treat high blood pressure. The combination of these drugs and Kamagra (Sildenafil) can increase the hypotensive effect of these drugs. You should also tell your doctor if you have or have had low blood pressure.
Cardiac conditions: If you have or have had heart disease or a heart attack or stroke, you should talk to your doctor before taking any erectile dysfunction medication. If you experience chest pains, dizziness or nausea during sex, the effort should be stopped and your doctor informed.
Kidney problems: If you have insufficient kidney function, you may need lower doses of this medicine.
Hepatic function: If you have a poor liver function, you may need lower doses of this medicine.
Nitrate-containing medicines: Sildenafil should never be taken with any medication containing nitrates. If Kamagra is taken with any medication containing nitrates (eg, nitroglycerin tablets, sprays or patches), or any other nitrate (eg, isosorbide dinitrate or amyl nitrite poppers), blood pressure may Suddenly falling to deadly levels. You may experience dizziness, fainting, heart attacks or strokes.
Penile Strain: As with other erectile dysfunction medications, men with an anatomical penile deformation such as angulation, cavernous fibrosis, or Peyronie’s disease should be closely monitored by their physicians if they take this medicine.
Prolonged erection: If an erection lasts more than 4 hours (a rare occurrence), seek immediate medical attention. If this condition is not treated quickly, tissue damage and permanent loss of ability to have an erection could result.
Prostate problems: tell your doctor if you are taking medicines, such as alpha-blockers (eg, doxazosin), to treat prostate problems, since the combination of these medicines with sildenafil may increase the blood pressure lowering effect of these medicines.
Vision problems / eye conditions: If you experience a sudden loss of vision in one or both eyes or other vision-related problems, contact your doctor immediately. Vision loss can be partial or complete. While in some cases the condition may improve over time, it can also be permanent.
Pregnancy and breast-feeding: Kamagra (Sildenafil) is not intended for use by women.
Children: Kamagra (Sildenafil) is not intended for use by children or adolescents under 18 years of age.
