Suscard tablets (glyceryl trinitrate)

How can this medicine affect other medicines?

It is important to tell your doctor or pharmacist what medicines you are already taking, including those bought without a prescription and herbal medicines, before you start treatment with this medicine. Similarly, check with your doctor or pharmacist before taking any new medicines while taking this one, to ensure that the combination is safe.

The medicines for erectile dysfunction (impotence) listed below must not be used by people taking glyceryl trinitrate, because the combination can produce a severe drop in blood pressure resulting in dizziness, fainting, or even a heart attack:

sildenafil (Viagra)

tadalafil (Cialis)

vardenafil (Levitra).

If this medicine is taken in combination with other medicines that reduce blood pressure, either as a treatment for high blood pressure (antihypertensives), or as a side effect, there may be an enhanced blood pressure lowering effect. This might make some people feel dizzy. If you do feel dizzy, you should lie down until the symptoms pass. Other medicines that can reduce blood pressure include the following:

ACE inhibitors, eg enalapril, captopril

alpha blockers, eg alfuzosin, doxazosin

alprostadil

anaesthetics

angiotensin II receptor antagonists, eg losartan

certain antipsychotic medicines, eg chlorpromazine

baclofen

benzodiazepines, eg temazepam

beta-blockers, eg propranolol

calcium channel blockers, eg diltiazem, verapamil, nifedipine

clonidine

diuretics, eg furosemide

hydralazine

levodopa

MAOI antidepressants, eg phenelzine

methyldopa

minoxidil

moxisylyte

moxonidine

other nitrates, eg isosorbide mononitrate, amyl nitrate (poppers)

tricyclic antidepressants, eg amitriptyline.

If you are taking medicines that can cause a dry mouth, Suscard tablets may be less effective because they are not able to dissolve properly. Medicines that can cause a dry mouth include the following:

anticholinergic medicines for Parkinson's disease, eg procyclidine, trihexyphenidyl, orphenadrine

anticholinergic medicines for urinary incontinence, eg oxybutynin, flavoxate, tolterodine, propiverine, trospium

antihistamines, eg brompheniramine, chlorphenamine

antispasmodic medicines, eg hyoscine

MAOI or tricyclic antidepressants, eg phenelzine, amitriptyline

antipsychotic medicines, eg chlorpromazine, clozapine.

If you experience this problem, you can help the tablet dissolve by moistening the area where you are going to place the tablet first, using your tongue or a little water.
