Drug allergies are adverse reactions to medication drugs and these reactions can be separated into three groups. First are those not actually related to the drug in question at all, but are coincidental and attributed to other mitigating factors associated with the illness or disease. Second are common predictable reactions like side effects related to taking other medication at the same time, or having an overdose. The third is unpredictable and uncommon reactions of which quite a few are allergic reactions that typically involve the immune system, being either immediate or delayed in reaction.

Allergic reactions can vary greatly from simple, slight rashes to very severe anaphylactic reactions of the immune system. Some drugs that can cause allergic reactions include heart drugs such as ACE inhibitors, antibiotics like penicillin, anesthetic drugs such as muscle relaxants, morphine, aspirin like drugs such as ibuprofen, chemotherapy drugs, antiseptics like iodine, vaccines such as tetanus, and colorings or preservatives in certain medications.

Reactions usually occur within one hour of taking the medication and can involve a measle-like rash that is very itchy. Some life threatening reactions may involve skin blistering with peeling accompanied by fever.

Common Allergic Reactions

Treatments of various drug allergic reactions involve the immediate withdrawal of the offending drug and then the administration of an antihistamine medicine. In severe allergic reactions, adrenaline and steroids may be used to save a life.

A headache involves having mild to severe pain in a specific, or many, areas of the head or back of the neck. Countless “types” of headache exist, all caused by a variety of reasons, and although they can be painful and rather annoying, they are, for the most part, not a sign of a serious disorder and in most non-chronic situations can be treated and relieved by medicines.

Although there is no single cause of a headache, several causes have so far been identified by the medical community and these can fall into two main categories – tension headaches and migraine headaches. Tension headaches are the result of contraction of the neck and head muscles and are the most common type of headache, accounting for nearly seventy percent of cases. Some causes of muscle contraction linked with tension headaches include stress, fatigue, eye strain, poor posture, hormonal changes, and alcohol or tobacco use.

Migraine headaches occur when blood vessels located in the neck and head constrict, which therefore leads to decreased blood flow in them. Symptoms of migraine include a throbbing pain usually on one particular side of the head, along with a feeling of nausea and sensitivity to sound or light. Migraines are usually chronic and affect more women than men

Headache

Although for the most part headaches are not a sign of anything sinister, as mentioned above, there are certain symptoms that need to be looked at by a doctor or physician immediately. These include a sudden onset of headache accompanied by vomiting or nausea; recurring headaches which are accompanied by memory issues, tiredness and difficulty in concentrating; neck stiffness accompanied by high fever; fits; vision irregularities, i.e. light flashes; trouble controlling, or loss of feeling in, the limbs; and difficulty in communicating while being tired and apathetic.

Blood pressure is described as the pressure the force of blood applies to the artery walls as it flows through them. It is the pumping action of the heart that causes the blood to be under pressure. Normal blood pressure is an essential function in the workings of the body. Blood pressure is denoted by two numbers, 120/80 being an example (which happens to be considered an average blood pressure reading, by the way), with the first number being the systolic blood pressure, or the pressure when the heart is contracted while pumping the blood, and the second number is the diastolic blood pressure reading which is when the heart is at rest while filling with blood.

Naturally low pressure (usually thought of as lower than 90/60) doesn’t indicate any problems health wise. It could be normal for some people and indeed beneficial as it can lower incidences of stoke and coronary heart disease. It only becomes a problem if it is accompanied by symptoms such as fainting. This is normally caused by an underlying problem which would indicate that the blood pressure is not being regulated properly.

What to do in the case of Low Blood Pressure

If someone has constantly low blood pressure, then this could be classed as normal, however, if they have postural hypotension (blood pressure drops when standing up from a sitting position) or postprandial hypotension (blood pressure drops after eating), could mean there are underlying health problems. These could be taking drugs that are used to treat high blood pressure, illnesses that cause blood loss, diabetes, Addison’s disease (an adrenal gland disease), and early stages of pregnancy.

Treatment of low blood pressure normally depends on the underlying cause of the problem.
