Kamagra 100 includes Sildenafil. It is a medication that works well for treating male erectile dysfunction (ED). A guy with erectile dysfunction is unable to get and/or sustain an erection strong enough for sexual activity. If you have a recent history of angina or a stroke, you should not take Kamagra 100. It is also not advised for those with heart or kidney issues. While undergoing treatment, try to avoid or consume alcohol in moderation as it can cause vertigo. You can take Kamagra 100 with or without food, although taking it at a set time is recommended.
