Sildenafil is widely used to treat Erectile Dysfunction (ED) and Pulmonary Arterial Hypertension (PAH).

Sildenafil Dose for Pulmonary Hypertension and Erectile Dysfunction

Sildenafil is available in doses of 20mg, 25mg, 50mg, and 100mg. Normally, a patient receives a dose of Sildenafil best suited to his/ her needs. This, therefore, require that you only purchase Sildenafil after being advised to do so by your doctor.

In the treatment of pulmonary hypertension, the common doses used are the 5mg and the 20mg ones. Normally, a typical dose for an adult consists of one 5 mg or 20 mg tablet to be taken thrice daily. The tablets are to be taken about 6-8 hours apart and should be taken routinely. This means that once you decide to be taking the drugs at specific times of the day, you should stick to those times. Moreover, in case you forget to take the medication, be sure to take it as soon as you remember. However, never double your dose. This dosage is for the oral therapy administration of Sildenafil, which may either be a suspension or tablets.

Sildenafil may also be in the form of an intravenous solution, which is stronger and more efficient than the tablets as it works faster. The intravenous form of Sildenafil is only given by a doctor. When it comes to treating pulmonary hypertension in children, the dose is specifically designed by the doctor, according to the child’s needs.

In general, the maximum dosage for Sildenafil while treating pulmonary hypertension is 20mg tablets, taken thrice a day. Also, it is essential to have basic knowledge of the guidelines involved when taking Sildenafil. For one, never stop taking the drug unless advised so by a doctor. This is because Sildenafil is used as a long-term medication when used as a pulmonary hypertension treatment and suddenly stopping its use may result in worsening of your condition. When it comes to the treatment of ED, the Sildenafil dosage usually involves taking one Sildenafil tablet 30-60 minutes before sexual activity. The tablet should be taken with water and can be taken with or without food. However, it is advised that one should avoid taking fatty foods while taking Sildenafil.

Also, avoid taking too much of the drug at once. This may lead to an increase in the intensity of the side effects and may lead to other complications such as lowering blood pressure to dangerous levels.

Sildenafil 20 mg Dosage

In most cases, the 20 mg dose of Sildenafil is used to treat pulmonary hypertension. As elaborated above, the maximum dose in this treatment is 20mg tablets, taken thrice a day, as specified by the doctor.

When Sildenafil is used in the treatment of erectile dysfunction, the 20 mg dose is not preferred by most users, some claiming that it was too weak, and its effects were not consistent. As such, most men have opted to take two or three tablets of the 20mg dose, amounting to 40mg and 60 mg respectively. This is so as to reach the levels of satisfaction they wanted to achieve. It is important to note that this should only be done upon being advised so by the doctor. Never increase your dose arbitrarily without first getting your doctor’s consent.

Sildenafil Uses

Sildenafil is used to treat erectile dysfunction in males and pulmonary hypertension in both females and males. Erectile dysfunction is a condition whereby a man is unable to get or maintain an erection long enough for successful sexual intercourse. It is also known as impotence. When used to remedy erectile dysfunction, Sildenafil works by enhancing the effects of nitric oxide, a chemical naturally produced by the body that relaxes muscles in the penis.

As a treatment for erectile dysfunction, Sildenafil is commonly known as generic Viagra. On the other hand, Sildenafil is known by its brand name, Revatio, when used to treat Pulmonary Hypertension. Pulmonary hypertension is a type of high blood pressure whereby the arteries carrying blood from the heart to the lungs are narrowed, and thus the heart has to work harder to pump blood through the arteries. Sildenafil remedies this situation by relaxing the muscles in the arteries’ walls. This then widens the blood vessels, in turn, reducing pressure in the arteries and thus blood flows more easily through them. This, in turn, improves blood flow to the lungs, making the heartbeat at a normal pace.
