Cobra

Cobra (Sildenafil Citrate) blocks the action of an enzyme known as cGMP-specific phosphodiesterase type-5 (PDE-5). This enzyme breaks down cGMP, a substance that induces smooth muscles to relax. Blocking PDE-5 means increased levels of cGMP within the smooth muscles which promotes muscle relaxation and vasodilation (a widening of blood vessels).

High levels of PDE-5 are found in the penis, lungs, and retina. PDE-5 is also found throughout the body within the smooth muscle cells of blood vessels and muscles.

Sildenafil Citrate belongs to the class of medicines known as PDE-5 inhibitors. Sildenafil Citrate increases blood flow to the penis following sexual stimulation. It does this by blocking the enzyme responsible for the breakdown of cGMP. cGMP is a substance that relaxes and widens blood vessels and smooth muscle cells. This allows men to keep an erection hard enough for sex.

Sildenafil Citrate only works following sexual stimulation. It works within 30 to 60 minutes, but may be taken up to four hours before sexual activity.

Sildenafil Citrate is used to treat erectile dysfunction (ED) and to reduce blood pressure in pulmonary arterial hypertension (PAH). It is taken when needed for ED and on a daily basis for PAH. A headache, stomach upsets and flushing are the main side effects.

Do not take more than one dose of Cobra (Sildenafil Citrate) per day.

Do not consume grapefruit or grapefruit products while taking Cobra (Sildenafil Citrate).

Always talk to your doctor before taking ANY medication for erectile dysfunction. Some erectile dysfunction medications are not suitable for men with certain medical conditions, and your doctor can advise you on an alternative.

Call your doctor immediately if you experience dizziness or feel nauseous during sexual activity, or develop pain, numbness, tingling in your chest, arms, neck, or jaw.

Do not take Cobra (Sildenafil Citrate) if you are also taking a nitrate drug (such as nitroglycerin or isosorbide dinitrate/mononitrate) for chest pain or heart problems. Do not take Cobra (Sildenafil Citrate) with recreational drugs such as "poppers". Taking these substances together can cause a sudden and dangerous drop in blood pressure.

Always buy your medications from a reputable supplier as there are a lot of counterfeit products on the market.

Certain lifestyle and psychological factors, such as smoking, drinking, and stress, can impact on erectile dysfunction. Eliminating these - for example, staying more active, losing weight if you are overweight, reducing alcohol intake, stopping smoking and reducing stress - may also help improve erectile dysfunction.

Never take other erectile dysfunction medications at the same time as taking Cobra (Sildenafil Citrate).

Seek urgent medical advice if an allergic reaction, sudden vision loss or painful erections lasting more than four hours occur.

Drinking alcohol after taking Cobra (Sildenafil Citrate) may lower blood pressure and decrease sexual performance.
