Will my medicine cause side effects?
The benefit of taking your medicine is expected to be greater than the risk of suffering any unwanted side effects.
Most of the peoples take medicine without suffering any unwanted side effect. But all medicines can cause problems.
The chance (risk) of having side effects can be described by following
· Very common means that more than 1 in 10 people taking this medicine are likely to have the side effects.
· Common means between 1 in 10 and 1 in 100 can cause the side effects.
· Uncommon means that between 1 in 100 and 1 in 1000 of peoples are affected.
· Rare means that between 1 in 1000 and 1 in 10000 of peoples are affected.
· Very rare means that less than 1 in 10000 of peoples are affected.
How can I reduce the risk of side effects?
· Take your medicines as advised by the doctor or by the pharmacist.
Do not take the medicine without the prescription of the medicine.
· If you feel any discomfort after taking a medication, immediately withdraw the next usage of medicine and consult a doctor immediately.
· For worrying or serious effects you may be told to stop medication or receive any other treatment. For less serious side effects you may be advised to continue medication or change a dose.
· If you are allergic to any medication, it is important to tell to your doctor or pharmacist.
· Be careful about mixing of medicines. Some medicines should not be mixed together.
Before taking any medicine it is important to tell to your doctor or pharmacist it about any other medicine you are taking already.
· Be aware that something can increase the chance your medicine causing side effects. For eg: you may able to lower the risk of side effects by not drinking alcohol or not eating certain foods during the course of treatment.
· Adopt correct drug administration technique.
What are the routes through which a medicine can administer?’
Most drugs can be administered by different route .The routes can be broadly classified into those for local action and systemic action.
Local routes- This route can be used for local lesions at accessible sites and for drugs whose systemic absorption from sites is minimal or absent.
The local routes are
Topical route
Deeper tissues- Deep tissue areas can be approached by using a syringe and needle. Eg: intra-articular injection (hydrocortisone acetate).
Arterial supply- It is used in angiography.
Systemic routes- The medicine administered through systemic route is intended to be absorbed into the blood stream and distributed all over.
1. Oral- It is the commonest mode of drug administration. Both solid dosage form and liquid dosage form can give through this route.
2. Sublingual or buccal- The tablet containing drug is placed under the tongue or crushed in the mouth and spread over the buccal mucosa. Eg: GTN, nitroglycerin, buprenorphine.
3. Rectal- Certain irritants or unpleasant drugs can be put into the rectum as suppositories or enema for systemic effect.
4. Cutaneous- Highly lipid soluble drugs can applied over the skin for long and prolonged absorption.
5. Inhalation
6. Nasal route.
7. Parental route- This refers to administration of medicine by injection directly into tissue fluid or to blood.
Parental route include subcutaneous, intramuscular, intravenous, intradermal.
8. Drugs which are giving through injection show faster action than the drugs given through oral route. Why?
The medicines which are giving through oral route, if it is solid form it must dissolve in aqueous phase and then cross the biological membrane in the body and get in to the blood circulation. Then the medicine goes into the site of action and shows drug action.
But in case of the drugs given through parental route by injection which takes the drugs directly into the tissue fluid or blood without having to cross biological membrane and shows the drug action. So the drugs given through the parental route has faster onset of action than given through oral route.
9. How to get most from your medicine?
Follow these Do’s and don’t:
· Do read the medicine strip or prescription carefully.
· Do take your medicine exactly as your doctor or pharmacist tells to you
· Do understand the generic and brand name of the medicine.
· Do look for an over the counter medicine that will treat only symptoms you have. for example, if you only have runny nose, don’t pick a medicine that also treats coughs and medicine
· Do make sure that each of your doctors has a list of all medicines you are currently taking.
· Do make sure that you have a list of all of the medicines you are currently taking.
· Don’t combine prescription medicine and OTC medicines unless your doctor says it’s okay.
· Don’t stop taking a medicine, change how much you take or how often you take it without first taking to your doctor.
· Don’t take someone else’s medicine.
· Don’t use medicine after its expiry date.
· Don’t crush, break or chew tablets or capsules unless your tells you to. Some medicine won’t work right unless they are swallowed whole.
10. Can we split tablet to adjust dosage?
Splitting of tablet is common. The patient’s need to split the tablets into two equal halves and take one tablet as one dose. The reason for the splitting of tablet is to obtain the required strength for the individual. Sometime the required strength of the tablet cannot be available commercially and the commercially available strength product may not be suitable.
Uneven breaking of tablet not only causing the inaccurate dose but may increase wastage too. The environmental exposure of broken tablet to air and light may affect the stability of the product.
Certain categories of tablets such as coated tablet, sustained release tablets are not suitable for splitting. On breaking of the coated tablet, the coating gets damaged and the purpose or benefit of coating may lose. similarly sustained releases tablets are designed for the purpose of achieve long duration of action from single dose. The design would be damaged on breaking. Pre packed oral contraceptives are not indented for splitting.
11. What are all should I check in the strip while buying a medicine?
Brand name of the medicine, date of manufacturing, expiry date, batch number of the medicine, dose and indications along with ingredients of the medicine and necessary precaution. These are all should be check in the strip of the medicine while buying a medicine.
12. How can I diffentiate brand name, generic name and chemical name of a medicine?
Brand name is the name assigned by the manufacturer and is his property or trade mark. One drug may have multiple brand names. For Eg: Calpol, Dolo, Medomol, Dolopar are the brand names of paracetamol.
Chemical name describes the name of the chemical substance present in the medicine. For Eg: 1-(Isopropylamino)-3-(1-naphthyloxy) propan-2-ol for propranolol.
Generic name is the name accepted by the competent scientific body or authority. For Eg: ciprofloxacin, cinnarizine, Omeprazole propranolol etc.
13. Is there any problem of changing brand name of my medicine?
The brand name and generic name of the product has been mentioned on the strip.
The manufactures may market the same product under different brand name in different countries. Brand names are generally differing in different countries. So the changing of the brand name of a medicine is not a problem.
But when you are purchasing another brand product you should check it out the generic name strength of the medicine and combination proportion and it should not be changed. For continuous use of medicine its better to go for the same brand as prescribed by the doctor.
14. Will any problem of taking the medicine after the expiry date?
All pharmaceutical products must carry the date of manufacturing and date of expiry on their label. The period between the two dates is called as life period or shelf life. Under specific storage conditions the product is expected to be remain stable during this period.
The expiry date does not means than the medicine has actually been found to lose potency or become toxic after it, but the quality of the medicine is not assured beyond the expiry date, and the manufactures is not liable if any harm arises from the use of the product.
Infact, majority of solid oral dosage forms (tablet, capsules etc.) stored under ordinary conditions in unopened containers remain stable for 1-5 years after the expiry date. Liquid formulations are less stable. Suspensions clump by freezing. Injectable solutions may develop precipitate, become cloudy or discoloured by prolonged storage.
An adrenaline injection in ampoule has been found to lose potency few months after expiry dates and it gets oxidized. Outdated tetracycline capsules produced renal tubular damage.
Though, majority of medicines, especially solid dosage forms remain safe and active years after the expiry date but their use cannot be legally allowed beyond this date.
15. Can one take allopathic medicine along with ayurveda medicines?
If not indicated otherwise by the doctor, Ayurveda Medicines can generally be taken along with allopathic medicines. Moreover, Ayurveda Medicines are used as adjuvant to allopathic medicines in most of chronic and degenerative diseases. As such there is no harm to consume simple over the counter medicine even without the prescription of the doctor but when they are using along with the ayurvedic medicine must be used after due consultation and advice of the doctor.
