Taking it
Like all anti-HIV drugs, nelfinavir must be taken in combination with other drugs to be completely effective.

Your doctor will advise you on the right combination of drugs to suit your circumstances.
Dosage
The normal adult dose is either 3 x 250mg tablets 3 times a day or 2 x 625mg tablets twice a day.
Regardless of what you read on this website or elsewhere, you should always take your medications according to your doctor's instructions. If you're unsure, speak to your doctor or pharmacist.
With or without food?

Side effects
All drugs can produce side effects in some people. These may be mild, moderate or severe, so you should be aware of potential side effects before starting any drug, and speak to your doctor if you experience side effects that concern you.
- Common side effects may include diarrhoea, nausea and headache.
- Less common side effects may include fat and metabolic irregularities.
It's unlikely you will experience all of these side effects, and you may not experience any side effects at all. Before starting any new drug, ask your doctor about side effects you might experience and discuss strategies for dealing with side effects if they do occur. If you experience any significant side effect you should continue taking your medicine and see your doctor as soon as possible.
Interactions with other drugs
Drugs to watch out for include other antiretrovirals, drugs to treat tuberculosis, for erectile dysfunction (such as Viagra), for heart rhythm (antiarrhythmics), and for migraine headaches. Interactions are also possible with several antihistamines (allergy medications), sedatives, drugs to lower cholesterol, and anti-fungal drugs. Make sure that your health care provider knows about ALL drugs and supplements you are taking. If you are taking nelfinavir and ddI, you should take ddI one hour before or two hours after nelfinavir.
