Kamagra 100mg Tablets Explained

Search for erectile dysfunction treatments and you will quickly run into the name Kamagra attached to a number. This article explains what the brand refers to, what the number on the box actually means, and the safety framework that applies in Australia. It deliberately contains no dosing guidance of any kind.

What the brand name refers to

Kamagra is a brand name used by an overseas manufacturer for products whose active ingredient is sildenafil citrate. The tablet form is the conventional presentation: a film-coated tablet in a blister strip. Sildenafil is the same ingredient found in the original brand-name sildenafil product and in generic sildenafil dispensed in Australian pharmacies.

Sildenafil is a Schedule 4 medicine in Australia, meaning prescription-only. That is a property of the ingredient, not of the brand, so no brand or format escapes it. The TGA also prohibits advertising prescription-only medicines directly to consumers, which is why this article describes rather than promotes.

What the number on the box means

The number in a product name of this kind refers to the labelled strength of active ingredient per tablet, expressed in milligrams. It is a manufacturing specification printed on the packaging — nothing more.

It is not a rating of quality, not a measure of how well a product works, and emphatically not a suggestion about what any individual should take. Which strength is appropriate for a particular person, if any medicine is appropriate at all, is a clinical decision. A prescriber weighs your age, cardiovascular health, kidney and liver function, other medicines, previous experience and tolerance before reaching it. Sildenafil is manufactured in several labelled strengths precisely because that decision varies between people.

If there is one point to carry away from this section: a bigger number is not a better product, and choosing a strength from a website is exactly the behaviour the prescription system exists to prevent.

How sildenafil works

Sildenafil is a phosphodiesterase type 5 (PDE5) inhibitor. During sexual arousal the body releases a signalling molecule that relaxes the smooth muscle in the blood vessels of the penis, allowing blood to flow in and remain. The PDE5 enzyme breaks that molecule down. Inhibiting the enzyme allows the relaxation signal to persist for longer.

Two implications follow. First, arousal is still required — the medicine does not create desire or act by itself. Second, because the mechanism involves blood vessels generally rather than one isolated area, effects such as flushing and headache are a predictable consequence of the same action, not a sign that something has gone wrong.

Contraindications and interactions

• Nitrates are an absolute contraindication. Glyceryl trinitrate, isosorbide products and the inhalants known as poppers must never be combined with a PDE5 inhibitor. The combination can cause a dangerous fall in blood pressure.
• Riociguat is likewise contraindicated.
• Alpha-blockers used for prostate symptoms or hypertension need careful management.
• Significant cardiovascular disease — recent heart attack or stroke, unstable angina, uncontrolled hypertension, some arrhythmias — must be assessed before any PDE5 inhibitor is considered, because sexual activity itself places demand on the heart.
• Liver or kidney impairment, low blood pressure, and inherited retinal conditions such as retinitis pigmentosa all change the picture.

Some antifungals, macrolide antibiotics, HIV protease inhibitors and grapefruit juice alter how sildenafil is processed by the body. Tell your prescriber and pharmacist about everything you take, including supplements and anything purchased online.

Recognised side effects

Effects commonly recognised for this class include headache, facial flushing, nasal congestion, indigestion, dizziness and mild visual disturbance. Less common but serious outcomes include priapism — a persistent, painful erection — sudden hearing loss and sudden vision loss.

Seek urgent care for chest pain during or after sex, an erection lasting more than four hours, or any sudden change in vision or hearing. If you need emergency treatment, say that you have taken a PDE5 inhibitor, because it rules out nitrate-based emergency medicines.

Registration, counterfeits and storage

A product being widely sold online does not mean it has been assessed by anyone. Products entered on the Australian Register of Therapeutic Goods have been evaluated by the TGA; products shipped from unregulated overseas sellers have not necessarily been evaluated at all, and the TGA has warned that such products have been found to contain undeclared or incorrect ingredients.

Practical checks: look for a legible batch number and expiry date, manufacturer name and address, intact packaging, and consistent printing. Be sceptical of any seller who offers to supply a prescription-only medicine without a prescription. Store tablets in their original blister, in a cool dry place below the temperature stated on the pack, away from sunlight and out of reach of children.

The conversation that matters more than the box

Persistent erectile difficulty is worth investigating rather than self-managing. It frequently coexists with high blood pressure, high cholesterol, diabetes or sleep apnoea, and picking those up early matters more for your long-term health than any product decision. A GP or telehealth prescriber can assess all of it in one appointment, and a pharmacist can answer medicine-specific questions at no cost.
