It is recommended to remove the patch before cardioversion or defibrillation.

Acclimatization to the preparation or other nitroderivatives may occur. For this reason, your doctor may recommend applying NITROFIX 5mg daily with a patch-free interval of8 to12 hours to maintain low plasma levels.

Nitroglycerin may interfere with the measurement of certain clinical analyses (catecholamines and vanillylmandelic acid in urine, increasing their excretion).

The administration of other vasodilators should be done with caution, in order to avoid the addition of effects.

The possibility of the ingestion of acetylsalicylic acid and non-steroidal anti-inflammatory substances decreasing the therapeutic response to NITROFIX5mg cannot be ruled out.

The action of this medication on the heart may be altered if used simultaneously with preparations containing sildenafil for penile erection (see contraindications).

Each NITROFIX5mg patch is contained in a small protective bag sealed. The adhesive area is covered by a protective film, which must be removed just before application to the skin.

Apply the NITROFIX5mg patch to the skin on a clean, dry, healthy (without residue) and relatively hairless area.

The correct application procedure is as follows:

1.- Open the bag, tearing it along the mark and remove the patch from its interior.

2.- Gently fold the patch with the dotted marks facing towards you, pull the tab and discard the protective film.

3.- Apply the adhesive surface to the upper arm or chest. Carefully separate the other dotted part from the protective film.

4.- Press the patch firmly to ensure good placement.

If you use more NITROFIX5mg than you should

High doses of nitroglycerin may, in some cases, cause a rapid drop in blood pressure and lead to shock, tachycardia, methemoglobinemia, cyanosis, coma, and seizures. Due to the controlled release of nitroglycerin with NITROFIX5mg, the risk of overdose is very rare. Any reduction in blood pressure and collapse symptoms can be treated by elevating the lower extremities. Severe methemoglobinemia can be treated with a methylene blue or thionine injection.

In case of overdose or accidental ingestion, consult the Toxicological Information Service. Phone: (91) 562 04 20.

Like all medications,NITROFIX5mgmay cause adverse effects, although not everyone will experience them.

The tolerance to nitroglycerin is generally good. Headache is the most common side effect, especially when high doses are used. This side effect is usually counteracted with common pain relievers, although in particularly intense cases, it may be necessary to reduce the dose or discontinue treatment.

Other possible side effects that may occur, especially at the beginning of treatment, are: arterial hypotension (especially postural), weakness, tachycardia, dizziness, palpitations, hot flashes, dizziness, nausea, vomiting, and dermatitis. Except for dermatitis, all of these are attributable to the pharmacological action of nitroglycerin. The doctor should be immediately informed of any side effects, allowing them to suspend treatment with NITROFIX5mg, at least temporarily.

The local tolerance is also generally good. Occasionally, it presents, and always depending on the level of application, itching, stinging, and mild redness reactions. However, these effects usually disappear a few hours after removing the patch without the need to take any other measures.
