Many men after 45-50 years of age encounter the problem of impotence, where it is impossible to achieve or maintain an erection. This delicate nuance can be resolved with a special drug – Viagra.
This drug has a stimulating effect on the penis, and its effect can last up to a few hours.
In order to properly use Sildenafil and get good use from it, it is recommended to carefully read the instructions, contraindications and possible side effects. You can get the drug without leaving your house by ordering it from Australian online pharmacy.
Composition and Form
The medicine is based on the main active ingredient of sildenafil in the form of citrate. Additional ingredients include anhydrous calcium pyrophosphate, magnesium stearate, titanium dioxide, and lactose.
It is available in tablet form, covered with a thin coating, with 50 – 100 mg of the active ingredient. The drug is presented in individual sections and packed in cardboard packaging.
Pharmacological Effects
This medicine supports a normal reaction to sexual stimulation of the male body.
How the drug works:
- The physiological process that causes an erection is impossible without the release of nitrogen in the cavernous bodies following sexual stimulation.
- Nitric oxide stimulates the action of a special enzyme of guanylate cyclase, which increases the level of cyclic guanosine monophosphate, relaxes the muscles of the cavernous bodies, and increases blood circulation within the intimate organ.
- Sildenafil is a selective inhibitor of PDE5, allowing for the decay of cGMP in the cavernous body.
- The medicine, therefore, has a peripheral effect on the erection of the penis.
Sildenafil is normally tolerated well by healthy men when used once in a dose of no more than 100 mg. The result can be noticed from 30 – 60 minutes after taking it.
Important! Viagra does not have a curing effect and is only effective when taken.
Indications
Sildenafil is prescribed for erectile dysfunction, whether it be:
- Psychogenic;
- Organic;
- Combined.
Repeated use is not permitted.
Method of taking it
Tablets are taken internally about 60 minutes before sexual activity. For the first time, the recommended dose is 50 mg once a day.
When considering individual tolerance and effectiveness of the drug, the dose can be lowered to 25 mg or increased to 100 mg. The maximum one-time dose is 100 mg.
Elderly people over 65 years old should not change their dose.
Contraindications and side effects
Viagra is forbidden to take in the following situations:
- Hypersensitivity to its ingredients;
- Anatomical deformities of the penis;
- Increased tendency for bleeding;
- Exacerbation of gastrointestinal ulcers;
- Liver, kidney dysfunction, especially – cirrhosis, renal failure;
- Pathologies that develop priapism – leukemia, myeloma, sickle cell anemia;
- Severe hypotension;
- Unstable angina, arrhythmia.
If you have had a stroke or a myocardial infarction in the last 6 months, do not take this drug.
Attention! Viagra is contraindicated for men who have within 1 – 3 days taken other medicines containing nitrates, including nitroglycerin. This causes blood pressure to drop sharply to life-threatening levels.
Side effects can last up to a few hours, and they include:
- Headaches;
- Reddening of the face;
- Diarrhea;
- Change in eye sensitivity to light;
- Blurred vision;

- Nausea, vomiting;
- Tremor, vertigo;

On rare occasions, there may be a temporary loss of vision in one or both eyes, a ringing sensation in the ears, or loss of hearing. Serious side effects occur rarely, but more common complaints include dizziness, increased excitability, and problems sleeping.
Important! If your erection lasts longer than 4 hours, you must see a doctor. This increases the risk of irreversible damage to the penis.
Overdose
In the case of an overdose, side effects will be more severe. Symptomatic treatment will be prescribed.
