Kamagra

Kamagra - Use | Dose | Side Effects

Kamagra is a medicine that contains an active substance called sildenafil. It works by blocking the enzyme phosphodiesterase type 5 (PDE 5), thereby increasing the level of nitrogen (II) oxide in the genitals, which causes dilation of blood vessels and increase blood flow to the genitals. It is used in men with erectile dysfunction and in men that cannot achieve and maintain an erection necessary for satisfactory sexual activity. Sexual stimulation is necessary for Kamagra to work.

Precautions

It should be avoided in the following conditions:

  • In patients allergic to the active substance called sildenafil or other similar medicines, such as:
    • vardenafil,
    • tadalafil, and others. If you are experiencing symptoms of an allergy, such as:
      • skin rash,
      • itchy skin,
      • redness of the skin,
      • swelling of the face,
      • swelling of the tongue,
      • difficulty breathing, contact your doctor immediately.
  • In patients with heart diseases (angina pectoris, heart failure and others).
  • In patients taking nitrates, used in the treatment of heart diseases, such as:
    • nitroglycerin,
    • isosorbide mononitrate,
    • isosorbide dinitrate,
    • pentaerithrityl tetranitrate, and others. Concomitant use of Kamagra with these medicines can cause hypotension (low blood pressure).
  • In patients who have nonarteritic anterior ischemic optic neuropathy (NAION). If you are experiencing vision changes, discontinue use and contact your doctor immediately.
  • In patients who have had a heart attack or stroke.
  • Patients with liver damage.
  • In patients with genital abnormalities.

Kamagra is considered a relatively safe medicine, and extra precautions should be taken in patients suffering from heart disease.

Sometimes Kamagra can cause dizziness. If dizziness occurs, do not drive or use tools or machines.

Use during pregnancy and breastfeeding

Kamagra can be used only in men and cannot be used in women.

How to use

Kamagra is found in the form of tablets as well as in the form of oral jelly (gel). Both, tablets and oral jelly should be taken one hour before sexual activity. The usual initial dose is 50 mg of Kamagra once a day. The dose can be increased to 100 mg once a day.

The maximum daily dose should not exceed 100 mg! It should be taken on an empty stomach, because food can slow the absorption of Kamagra. If you take this medicine with food, the effect will manifest later (after 90-120 min).

It should be avoided in patients under the age of 18.

It is not recommended use of this medication in combination with alcoholic beverages, because of the risk for side effects, although there are no enough data about concomitant use of Kamagra with alcoholic beverages.

Increasing the dose of Kamagra (e.g. to 200 mg), does not increase frequency or strength of erections. Instead, increasing the dose of Kamagra, increase the risk of side effects. Therefore, you should never use the dose higher than 100 mg once a day.

Use with other medicines (Interactions)

Kamagra should be avoided in combination with the following medicines:

  • Nitrates, drugs used in the treatment of heart disease, such as:
    • isosorbide mononitrate,
    • isosorbide dinitrate,
    • pentaerithrityl tetranitrate,
    • nitroglycerin, and others. Concomitant use with these medicines, increase the effect of nitrates and can lead to hypotension (low blood pressure).
  • Alpha blockers, drugs used in the treatment of heart diseases and in the treatment of benign prostate enlargement, such as:
    • doxazosin,
    • prazosin,
    • terazosin, and others. Concomitant use of Kamagra with these medicines, increase the effect of alpha blockers and can lead to hypotension (low blood pressure).
  • Antibiotics, drugs used in the treatment of bacterial infections, such as:
    • erythromycin,
    • clarithromycin,
    • azithromycin, and others. These medicines may increase the level of Kamagra in the blood, increasing the risk for side effects.
  • Grapefruit juice may increase the level of Kamagra in the blood and increase the risk for side effects.
  • Medicines used in the treatment of HIV infections, such as:
    • ritonavir,
    • saquinavir,
