Read guideDapoxetine
Dapoxetine is a prescription medicine used to treat premature ejaculation (PE) in adult men. It belongs to a group of medicines known as selective serotonin reuptake inhibitors (SSRIs), but unlike SSRIs used for depression it is taken on an as-needed basis shortly before sexual activity rather than every day. It is sometimes prescribed alongside a PDE5 inhibitor where both conditions are present, but only under medical supervision.
Read guideConjugated Oestrogens
Conjugated oestrogens are a prescription-grade form of hormone (oestrogen) therapy. As a vaginal cream, such as Premarin cream, they are used in women to relieve local symptoms of vaginal and vulval tissue thinning (atrophy) that can occur around and after the menopause, such as dryness, irritation and discomfort. This is a women's product containing active female hormones and should only be used under the direction of a doctor.
Read guideCarisoprodol
Carisoprodol is a centrally acting skeletal muscle relaxant, marketed under brand names such as Pain-O-Soma and Prosoma. It is used as a short-term adjunct to rest, physiotherapy and other measures for the relief of discomfort associated with acute, painful musculoskeletal conditions. It is intended only for brief courses of treatment and is not suitable for managing long-term or chronic muscle pain.
Read guidePregabalin
Pregabalin is a prescription medicine used to treat neuropathic (nerve) pain, certain types of epilepsy (as an add-on treatment for partial seizures) and generalised anxiety disorder. In many countries it is classified as a controlled drug because of its potential for misuse and dependence. It is available under various brand and generic names and should be used only under medical supervision.
Read guideZopiclone
Zopiclone is a prescription medicine used for the short-term treatment of insomnia (difficulty falling asleep, waking during the night, or early-morning waking). It belongs to a group of medicines often called 'Z-drugs' (non-benzodiazepine hypnotics), which act in a similar way to benzodiazepines. Because of the risk of tolerance and dependence, it is normally prescribed only for a short period, and in Australia it is a Schedule 4 (prescription-only) medicine.
Read guideModafinil
Modafinil is a prescription medicine used to promote wakefulness in adults with excessive sleepiness associated with certain conditions, such as narcolepsy, obstructive sleep apnoea (alongside treatment for the underlying breathing problem) and shift-work sleep disorder. It is described as a wakefulness-promoting agent. In many countries it is a prescription-only and controlled medicine and should be used only under medical supervision.
Read guideAmoxicillin
Amoxicillin is a broad-spectrum antibiotic belonging to the penicillin family (an aminopenicillin). It is prescribed by doctors to treat a range of bacterial infections, including certain chest and respiratory tract infections, ear, nose and throat infections, urinary tract infections, and some skin and dental infections. It works only against bacteria and has no effect on infections caused by viruses, such as colds and most cases of flu.
Read guideSulfamethoxazole + Trimethoprim
Sulfamethoxazole with trimethoprim, often called co-trimoxazole (and known by brand names such as Bactrim), is a combination antibiotic that pairs two active ingredients in a fixed ratio. It is prescribed for certain bacterial infections, including some urinary tract infections and particular chest infections, and has an established role in preventing and treating a type of pneumonia (Pneumocystis pneumonia) in vulnerable people. It is effective only against susceptible bacteria, not viruses.

Ivermectin is an antiparasitic medicine used to treat certain infections caused by parasites. In its established medical uses it is prescribed for particular worm (helminth) infections, such as some intestinal worm infestations and river blindness (onchocerciasis), as well as some other parasitic conditions. Topical formulations are also used for certain skin conditions involving parasites, such as head lice and the inflammatory skin condition rosacea. It should be used only for its intended, approved purposes under medical guidance.
Read guideFenbendazole
Veterinary onlyFenbendazole is a veterinary antiparasitic medicine belonging to the benzimidazole class. It is used in animals — including dogs, cats, horses, livestock and other species — to treat infections caused by gastrointestinal worms and certain other parasites. It is a veterinary product and is not an approved medicine for use in humans; it should be used only in animals, for its intended antiparasitic purpose, under the guidance of a veterinary surgeon.
Read guideHydroxychloroquine
Hydroxychloroquine, sometimes abbreviated HCQS, is a medicine used in the prevention and treatment of malaria caused by certain Plasmodium parasites, and in the long-term management of some autoimmune conditions.

It should be used only for these approved purposes, under the supervision of a doctor.
Read guideFrequently asked questions
What is this ingredient index?
It lists every active-ingredient reference hub on Kamagra AUS — one page per molecule (e.g. Sildenafil, Tadalafil, Pregabalin) covering how it works, how it's taken, side effects and safety, with links to the branded products that contain it.
Are all of these ingredients human medicines?
Almost all are — the exception is Fenbendazole, a veterinary antiparasitic. Its hub explains what it is and why it is not an approved medicine for human use, rather than presenting it as one.
Are these ingredient guides medical advice?
No. They are general reference information written by our pharmacy team to help you understand a molecule. They don't replace a consultation — always speak to a doctor or pharmacist and read the patient information leaflet before taking any medicine.
How do I find products containing a specific ingredient?
Open the ingredient's hub page — each one lists every generic product we stock that contains that molecule, across brands, formats and pack sizes, with a link to browse the full commerce category.
