  • Dizziness
  • Abnormal or blurry vision
  • Vomiting
  • Flushing, and
  • Rashes

These are some common side effects thatED medications, even Kamagra 100mg oral jelly can develop. However, these side effects are generally mild, tolerable, and fade away in a couple of days or a week. Though, if any of these side effects persist; immediately seeking a doctor’s help can be helpful.

Viagra (Sildenafil)

It is no secret that Viagra containing sildenafil citrate is the first FDA approved oral medication to treat erectile dysfunction. Branded and patented by Pfizer, Viagra was approved back in 1990s and is available in 50mg to 200mg Viagra dosages.Since sildenafil was one of the vasodilators, it helped countless men stronger and lasting erection while sexually aroused.

But now, as we talk about its side effects and their frequency, Viagra (sildenafil) is doubtlessly a go. Anyways, Viagra is the most prescribed ED medication by doctors.

Sildenafil is one of the optimal vasodilator drug; it is simply effective yet less likely to develop any sort of side effects. Even as a precaution, one can start with its lowest dosage and step up it accordingly if the current one does not work.

Cialis containing tadalafil is another FDA approved medication, also known as “the weekend pill” for its long lasting effectiveness up to 36 hours in a single dose. Cialis is available in 5mg to Cialis 60mg dosages and pretty effective to help achieve and maintain a decent erection during sex.

Similarly as Viagra, the chances of tadalafil to develop any side effects are rare. But sometimes, Cialis (tadalafil) can develop priapism or prolonged erection which results in damage to penile tissues.

However, it depends on the doctor and the patient’s need and health condition to be prescribed with a specific medication. If the patient finds Cialis more suitable and effective than any other ED medication, doctor would prefer prescribe that only.

Levitra (Vardenafil)

Levitra containing vardenafil is a strong ED medication. It is available in 10mg to 40mg Levitra dosages and generally prescribed to men with higher degree of erection problem.

When other ED medications are found less effective in a patient’s case, doctor prescribes Levitra tablets.But yes, it is possible that Levitra develop some side effects if mistakenly overdosed or were unsuitable. However, under a doctor’s prescription, one can take Levitra as well.
